Pomace

Pomace is the solid residue remaining after the mechanical pressing of fruits or vegetables to extract juice, cider, wine, or oil, typically comprising the skins, pulp, seeds, stems, and any residual fragments left behind.^[1] This by-product is generated in large quantities by the food processing industry, with examples including apple pomace from juice production, grape pomace from winemaking, and olive pomace from oil extraction.^[2]^[3] Compositionally, pomace is rich in dietary fiber, polyphenols, proteins, lipids, and minerals, varying by fruit type; for instance, grape pomace contains high levels of phenolic compounds and seeds that yield valuable oils, while olive pomace includes 70–90% pulp, 9–27% stones, and residual oil content around 2%.^[4]^[3] Apple pomace, similarly, is a source of pectin, antioxidants, and bioactive components like flavonoids, making it suitable for further valorization.^[5] Moisture content and pH vary by pomace type and processing method; for example, olive pomace has 45–70% moisture and pH 4.8–5.2.^[3] Despite its nutrient density, pomace is frequently underutilized and discarded, contributing to environmental challenges such as landfill fermentation and water contamination from bacterial byproducts.^[6] However, it holds significant potential for sustainable applications, including animal feed, composting, biofuel production (e.g., bioethanol or biogas), and food industry uses like fortifying baked goods, extracting pectin for gelling agents, or recovering antioxidants for health-promoting products.^[1]^[3] In olive oil processing, pomace is further refined to produce olive-pomace oil, a blend of refined pomace oil and virgin olive oil suitable for consumption.^[7] Research continues to explore its role in enhancing food functionality, such as adding grape pomace extracts to meat products for antimicrobial and coloring effects.^[4]

Definition and Terminology

Definition

Pomace is the solid residue that remains after the pressing or crushing of fruits, vegetables, or seeds to extract juice, oil, or other liquids.^[8] This byproduct typically consists of skins, seeds, stems, and pulp, forming a fibrous, pulpy material with an initially high moisture content, often up to 70%.^[9]^[10] The basic formation of pomace occurs through mechanical pressing or centrifugation following the harvesting and initial processing of the source material.^[11] It is distinct from related terms such as "marc," which specifically denotes grape pomace, and "bagasse," the fibrous residue from sugarcane crushing.^[12]^[13] Commonly obtained from sources like olives and grapes, pomace serves as a versatile agricultural byproduct.^[14]

Etymology

The term "pomace" originates from the Latin pomum, meaning "fruit" or specifically "apple," which evolved through Medieval Latin pomācium (referring to cider) and into Old French pomaz or pomace, denoting the dregs or lees of cider production.^[15] This linguistic path reflects the word's initial association with the pulpy residue left after pressing fruits for juice or cider in medieval Europe.^[16] English adoption of "pomace" occurred in the 16th century, primarily describing the solid pressings from apples in cider-making, as documented in early modern texts on agriculture and distillation.^[17] By the 17th and 18th centuries, the term underwent a shift, broadening from apple-specific usage to encompass the residue from other fruits like grapes and olives, aligning with expanding horticultural practices in Europe.^[15] Distinct from broader terms like "lees," which refer to the liquid sediment or dregs (such as dead yeast and fine particles settling in wine or cider), "pomace" specifically denotes the coarse, solid remnants of skins, pulp, seeds, and stems after mechanical pressing.^[18] This differentiation highlights pomace's role as a fibrous byproduct versus lees' finer, suspended matter.^[19] Linguistic variations appear in other Romance languages, such as Spanish "orujo," which designates the pomace from grapes or olives before distillation into spirits, rooted in regional pressing traditions.^[20] Similarly, "piquette" in French describes a low-alcohol beverage produced by rehydrating pomace, derived from piquer ("to prick"), evoking its mild effervescence from secondary fermentation.^[21]

Types and Sources

Fruit Pomace

Fruit pomace refers to the solid residues remaining after the extraction of juice, oil, or other primary products from various fruits, primarily consisting of skins, pulp, seeds, and sometimes stems. Among the most prominent types, grape pomace, also known as marc, is generated during winemaking and accounts for 20-25% of the original grape weight, comprising skins, seeds, and residual pulp that are particularly rich in tannins and polyphenolic compounds concentrated in the seeds.^[22] These components contribute to its astringent properties and potential for secondary uses, with condensed tannins making up 20-51% of the dry weight in some varieties.^[23] Apple pomace arises from cider and juice production, representing a significant byproduct with high pectin content, a soluble fiber that constitutes up to 11-15% of its dry matter, making it a key commercial source for pectin extraction.^[24] Globally, the apple processing industry produces approximately 4 million tons of apple pomace annually, derived from over 87 million tons of apples processed for juice and cider.^[25] This pomace is characterized by its fibrous texture, including peels and core remnants, and retains substantial nutritional value from the fruit's original composition. Olive pomace results from olive oil extraction and exists in two primary forms: that obtained after mechanical pressing (first press), which retains higher moisture (25-45%), and exhausted pomace following solvent extraction to recover residual oil.^[26] The initial pomace after pressing contains 5-8% residual oil trapped in the pulp, skins, and fragments, which is subsequently extracted using solvents like hexane to produce pomace olive oil.^[27] This type of pomace is drier and more fragmented compared to grape or apple variants, with variations depending on extraction methods such as traditional pressing, three-phase centrifugation, or two-phase systems. Pomace from other fruits, such as citrus (including orange and lemon), cherry, and pomegranate, exhibits diverse traits based on the fruit's structure and processing. Citrus pomace, primarily peels and pulp from juice extraction, yields about 50% of the fruit's weight and is notable for its high fiber and essential oil content in the albedo layer.^[28] Cherry pomace, a byproduct of juice or wine production, constitutes 15-28% of the fruit mass, featuring seeds and skins rich in anthocyanins and organic acids.^[29] Pomegranate pomace, mainly peels (30-50% of fruit weight) with minor seed inclusion, is abundant in ellagitannins and fibers, often comprising 96% peels in juice processing residues.^[30] These fruit-specific pomaces highlight the variability in yield and bioactive profiles, influenced by the fruit's pulpy nature and extraction intensity.

Non-Fruit Pomace

Non-fruit pomace refers to the solid residues obtained from the processing of seeds, nuts, and vegetables, distinct from fruit-derived materials due to variations in texture, oil retention, and fiber profiles. These by-products arise primarily from oil extraction in seeds and nuts or juicing in vegetables, resulting in materials that are often drier and more meal-like compared to the pulpier consistency of fruit pomace. Seed and nut pomace typically exhibit a low moisture content and a powdery or granular texture, making them suitable for diverse industrial applications, while vegetable pomace retains higher water levels, leading to a fibrous, moist residue. Seed and nut pomace is generated during the mechanical pressing of oilseeds such as sunflower and soybean, where the residual oil content ranges from 0.5% to 8.9% in soybean cake and 1.0% to 23.6% in sunflower cake, depending on extraction efficiency.^[31] This pomace possesses a dry, meal-like consistency, with sunflower cake often containing 13–36% fiber, contributing to its use as a protein- and fiber-rich byproduct.^[31] In contrast to fruit pomace, which typically has moisture levels ranging from 45% to 70%, seed pomace is drier, facilitating easier storage and processing.^[8] Vegetable pomace, derived from juicing processes, includes residues from tomatoes and carrots, characterized by high dietary fiber content—up to 53.97 g/100 g in tomato pomace and 37–55% in carrot pomace—and low oil levels, typically below 2%.^[32]^[33] Tomato pomace, a mixture of skins, seeds, and pulp, provides 48.62–53.97 g/100 g dietary fiber, enhancing its value as a functional ingredient.^[32] Carrot pomace similarly offers substantial fiber, with levels reaching 55% total dietary fiber, alongside minimal fat content.^[33] Specific examples illustrate the diversity of non-fruit pomace. Almond pomace, a fibrous byproduct from nut milk production, results from straining blended almonds and water, yielding a wet pulp that can be dried into a meal-like form rich in protein and fiber.^[34] Cocoa pomace, known as press cake from chocolate processing, retains 10–12% fat after butter extraction from cocoa liquor, providing a semi-solid residue with applications in powder production.^[35] Yields of vegetable pomace vary by crop but often constitute 20–50% of the input weight, attributed to the high water content (62–70%) in raw vegetables like tomatoes and carrots, which limits juice extraction efficiency.^[32]^[33] For tomatoes, pomace represents 5–30% of raw fruit weight, while carrot processing leaves up to 50% as pomace.^[32]^[33] These yields underscore the substantial volume of non-fruit pomace generated annually, promoting opportunities for valorization.

Historical Development

Ancient and Medieval Uses

In the ancient Mediterranean, particularly during the Roman period, olive pomace—the solid residue left after olive oil extraction—was valued for practical uses such as fuel and animal fodder. Olive pomace was employed as a fuel, burning at a high and consistent temperature ideal for heating, cooking, and firing pottery or lime kilns.^[36] Historical agricultural texts from the era also describe olive pomace being incorporated into cattle feed in Italy, often as silage mixed with chopped straw and tree leaves to supplement diets during periods of scarcity.^[37] During the medieval period in Europe, from the 12th to 15th centuries, apple pomace found widespread application in fermentation processes to produce vinegar and low-strength second-press beverages, often referred to as ciderkin or similar dépense. This method involved steeping the crushed fruit residues in water to extract remaining sugars, yielding a modest alcoholic beverage or, upon further acetification, vinegar used for preservation, flavoring, and medicinal purposes among rural communities.^[38] Such practices maximized resource use in agrarian societies where fruit pressing was a seasonal staple, reflecting the era's emphasis on thrift in food production.^[39] Limited distillation of grape pomace into spirits emerged in 14th-century Italy, where residues from winemaking were processed to create rudimentary eaux-de-vie, primarily in northern regions like the Alps and Trentino-Alto Adige. This innovation, documented in early records and legends, allowed peasants to transform winery waste into a potent potable, marking an initial step toward modern pomace brandies like grappa.^[40]

Industrial Era Advancements

The Industrial Era marked a significant shift in pomace utilization, transitioning from traditional manual methods to mechanized processes that enhanced efficiency and scalability. In the 19th century, the adoption of hydraulic presses in Italy, particularly in regions like Puglia, revolutionized olive oil extraction by applying greater pressure to olive paste, yielding higher volumes of oil and leaving behind pomace suitable for secondary processing. This innovation, emerging around the mid-1800s, allowed for more systematic handling of pomace residues, which were increasingly valued for further oil recovery or other uses.^[41]^[42] Concurrently, France experienced a rise in pomace brandy production, known as marc, as distillation techniques industrialized amid expanding viticulture and the phylloxera crisis of the late 19th century, which prompted greater reliance on by-product spirits to sustain the wine industry.^[43] The 20th century brought further advancements, including the introduction of solvent extraction methods in the 1920s for recovering residual oils from pomace, a technique initially developed for seed oils but adapted to olive and fruit residues to maximize resource use. During World War I and II shortages, pomace—such as castor and apple varieties—served as a critical fertilizer alternative when synthetic and other organic options like cottonseed meal became scarce, supporting agricultural needs amid global disruptions.^[44]^[45] Post-1950, globalization and mechanized agriculture amplified pomace surpluses from intensified fruit and wine production, leading to its widespread incorporation into animal feed; for instance, ensiled grape pomace became a staple in European livestock diets for its fiber and energy content, reducing waste while enhancing feed sustainability. Annual grape pomace output in major EU producers like Italy, France, and Spain was approximately 1.5 million tons as of the early 2000s.^[14]^[46]^[47] Environmental concerns in the late 1970s drove regulatory changes across Europe, with EU waste directives such as 75/442/EEC and subsequent national policies in Italy from the 1980s emphasizing pomace recycling—through composting or energy recovery—over open disposal to mitigate pollution from olive and grape processing effluents.^[48]

Production Methods

Extraction Processes

Pomace extraction primarily involves mechanical separation techniques to isolate the solid residue from liquid components in raw materials such as fruits and olives. In mechanical methods, the process begins with crushing or grinding the raw material to break down cellular structures, followed by pressing using screw or hydraulic presses to separate the liquid fraction. This approach is commonly applied to grapes and olives, achieving a liquid separation yield of approximately 70-80% by weight, leaving behind the pomace as the solid byproduct.^[49]^[50] Centrifugation serves as a high-speed mechanical separation method, particularly in olive oil production, where a decanter centrifuge processes the crushed olive paste to isolate oil, water, and solids. In two-phase centrifugation systems, this results in wet pomace with a moisture content of 55-75%, typically around 60-70%, which facilitates efficient liquid removal while retaining higher water levels in the residue compared to traditional pressing.^[51]^[52] For recovering residual oils from dried pomace, solvent extraction employs chemical solvents such as hexane to dissolve and separate the remaining lipids from the solid matrix. This method is applied after initial mechanical dewatering and drying of the pomace to about 8% moisture, enabling up to 95% oil recovery efficiency by solubilizing the oil for subsequent distillation and separation.^[53]^[54] Extraction variations depend on the source material to optimize yield and quality. For apple pomace in juice production, cold-pressing at ambient temperatures preserves bioactive compounds, contrasting with hot-pressing methods used for seed pomace, where elevated temperatures enhance oil extraction efficiency from materials like grape or olive seeds. Modern processing plants often incorporate waste heat recovery systems, utilizing thermal energy from drying or centrifugation exhaust to reduce energy consumption during pomace dewatering.^[55]^[56]^[57]

Composition and Properties

Pomace, the solid residue remaining after the extraction of juices or oils from fruits and other sources, exhibits a diverse chemical composition influenced by the raw material and processing conditions. Macronutrients in fruit pomace typically include high levels of dietary fiber, ranging from 20% to 60% on a dry weight basis, with grape pomace often containing 26% to 70% fiber, including exceptional lignin levels of 18% to 55%. Protein content generally falls between 5% and 15%, as seen in grape pomace at approximately 8.5% and apple pomace around 4%. Lipids are present in lower amounts, typically 2% to 10%, with variations such as 2.6% in apple pomace and up to 13.8% in berry pomace. Polyphenols, particularly in grape pomace, can reach up to 50 g/kg dry weight, contributing to its bioactive profile.^[58]^[59]^[60] Micronutrients in pomace include antioxidants such as resveratrol, predominantly found in grape pomace at levels up to 26.5 mg/g in extracts, alongside other polyphenols like flavanols and anthocyanins. Minerals, comprising 1% to 5% of dry weight as total ash, feature potassium and calcium as major components, with potassium often at 0.3% to 3.3% (3 to 33 g/kg) and calcium at 0.09% to 0.3% (0.9 to 3 g/kg) in apple and grape pomace. These elements, along with phosphorus and magnesium, vary by source but provide essential nutritional value.^[61]^[62]^[59] Physical properties of fruit pomace include an acidic pH typically ranging from 3.5 to 5.0, such as 4.24 in grape pomace and 4.33 in apple pomace, which supports its stability but also promotes rapid microbial activity. Bulk density is generally 0.4 to 0.6 g/cm³, as observed in carrot and olive pomace at 0.45 to 0.56 g/cm³, facilitating handling in industrial applications. Pomace demonstrates high biodegradability, leading to quick fermentation due to its organic content and microbiota, enabling spontaneous processes that enhance valorization through microbial activity.^[63]^[64]^[65]^[66] Composition varies significantly by source; for instance, olive pomace contains higher lignin levels, up to 30% to 42% dry weight, reflecting its lignocellulosic structure, while apple pomace has elevated residual sugars at 10% to 20% (or higher in some varieties, up to 30 g/100 g total sugars). Grape pomace, in contrast, balances high fiber and polyphenols but lower sugars compared to apple, with red wine varieties at 4% to 9% versus white at 28% to 31%. These differences arise post-extraction and depend on fruit type, cultivar, and processing.^[67]^[62]^[58]

Applications

Beverage Production

Pomace brandy, also known as grappa in Italy or marc in France, is produced through the distillation of fermented pomace derived from grapes or other fruits after pressing. The process begins with the fermentation of the pomace, where residual sugars in the skins, seeds, and stems are converted to alcohol by yeast, typically yielding a low-alcohol wash of around 5-10% ABV before distillation.^[68] This wash is then double-distilled in copper pot stills or continuous column stills to concentrate the alcohol, resulting in a clear spirit with an alcohol by volume (ABV) typically ranging from 35% to 60%, though most commercial examples fall between 40% and 45%.^[69] The spirit is often aged in oak barrels to develop flavor complexity, imparting notes of fruit, nuts, and spice, and must meet regional standards for appellation, such as Italy's requirement for 100% Italian pomace in true grappa.^[69] In winemaking, grape pomace serves as an aid in secondary fermentation to produce piquette, a low-alcohol beverage traditionally made by rehydrating the pomace with water after primary wine pressing and allowing a second fermentation. This process extracts residual sugars and compounds from the pomace, resulting in a lightly effervescent wine with 4-7% ABV that gains enhanced color from anthocyanins and structure from tannins released during extended maceration of the skins and seeds.^[70] Piquette's production valorizes pomace that would otherwise be discarded, contributing to sustainable winery practices while providing a rustic, fruity profile distinct from standard wines.^[70] Apple pomace, obtained after pressing for cider, can be repurposed for second-run cider by soaking the residue in water to rehydrate and extract remaining juices, followed by a secondary pressing and fermentation to yield a lighter, lower-alcohol beverage often around 2-4% ABV.^[71] This second-run product, sometimes called "small cider," captures additional flavors from the pomace's fibrous components. Alternatively, apple pomace undergoes acetic acid fermentation to produce vinegar, where the material is first enzymatically treated to break down fibers and release sugars, enabling alcoholic fermentation by yeast, followed by conversion to acetic acid by Acetobacter bacteria, achieving typical vinegar strengths of 4-6% acidity.^[72] This two-stage process transforms the pomace into a tangy, antioxidant-rich vinegar suitable for culinary uses.^[72] Modern innovations have expanded pomace's role in beverage production, particularly through infusion into craft beers and liqueurs to enhance flavor and nutritional profiles. Fermented apple or grape pomace is added during brewing to impart fruity esters, tannins, and phenolic compounds, creating beers with complex aromas and up to 150% higher polyphenol content compared to standard varieties, as seen in experimental purple grape pomace-infused ales.^[73] Similarly, pomace extracts flavor liqueurs by maceration in alcohol, yielding spirits with elevated bioactive antioxidants. Globally, the wine industry generates 10.5 to 13.1 million tons of pomace annually, with a significant portion destined for brandy production, underscoring the scale of these applications.^[74]

Food and Feed Uses

Pomace serves as a valuable ingredient in human food products, particularly for enhancing nutritional profiles. Apple pomace, rich in dietary fiber, is commonly incorporated into baked goods such as muffins, cakes, and bread as a fiber supplement, with inclusion rates up to 20% maintaining acceptable texture and sensory qualities while boosting fiber content to levels that support digestive health.^[75] Similarly, olive pomace oil, extracted from the residue of olive processing, is utilized in cooking applications like frying and baking due to its high smoke point and stability under heat, providing a cost-effective alternative to higher-grade olive oils without compromising flavor in prepared dishes.^[76] In animal nutrition, pomace is widely used as a feed component, especially for ruminants. Grape pomace, a byproduct of winemaking, can be included in ruminant diets at 10-20% of dry matter, offering fiber and moderate protein levels (typically 3.5-14% by weight) that support rumen fermentation and overall performance in livestock such as dairy cattle, where it contributes to improved milk fatty acid profiles.^[77]^[78] Its protein content aids in maintaining nitrogen balance, making it suitable for supplementing basal feeds in dairy operations. The nutritional benefits of pomace in both human and animal diets stem from its high fiber and antioxidant content. Dietary fiber from pomace promotes gut health by enhancing microbiota diversity and aiding digestion, while polyphenols act as antioxidants that reduce oxidative stress and support immune function in supplements or fortified foods.^[9] Examples include pomace-based pet treats, such as those using apple pomace, which provide soluble fiber for bowel regularity and gut support in dogs.^[79] Processing pomace for food and feed applications typically involves drying to reduce moisture content to around 10%, preventing microbial spoilage and enabling long-term storage in powder or pellet form.^[80] The global market for pomace in animal feed exceeds $1 billion annually, driven by its role in sustainable nutrition across livestock sectors.^[81]

Industrial and Agricultural Applications

Pomace finds significant application in industry as a biofuel, leveraging its calorific value of 15-20 MJ/kg to serve as a renewable energy source comparable to other biomass materials.^[82]^[83] This property stems from its lignocellulosic composition, enabling combustion or gasification for heat and power generation in facilities processing agricultural residues.^[82] In the cosmetics sector, polyphenols extracted from pomace are incorporated into anti-aging creams for their potent antioxidant effects, which help mitigate oxidative stress and support skin barrier function.^[84]^[85] These bioactive compounds, including hydroxytyrosol, provide natural alternatives to synthetic preservatives and enhance product efficacy in dermatological formulations.^[86] Beyond energy and personal care, the fibrous structure of pomace supports paper production by substituting for conventional wood pulp in molded fiber products and packaging materials.^[87] This utilization repurposes the cellulose-rich residue into sustainable alternatives for absorbent papers and eco-friendly containers.^[88] Pomace also undergoes anaerobic digestion to produce biogas, yielding approximately 200-300 m³ of methane per ton, which can be captured for renewable energy while generating nutrient-rich digestate.^[89] This process efficiently converts the organic matter into methane-rich gas, with yields enhanced by co-digestion strategies.^[90] Agriculturally, pomace functions as a fertilizer and soil amendment, providing slow-release nitrogen at levels of 1-2% over several months to support crop nutrition without rapid leaching.^[91] Its application improves soil organic matter and microbial activity, fostering long-term fertility in amended fields.^[92] As a mulch, pomace layers suppress weed emergence by blocking light and retaining soil moisture, reducing the need for herbicides in orchard and vineyard management.^[93] This practice enhances water use efficiency and soil structure while minimizing erosion on sloped terrains.^[94] In the European Union, widespread adoption of pomace-based fertilizers promotes sustainable agriculture by decreasing dependence on synthetic inputs, thereby lowering environmental impacts from chemical production and application.^[95]

Regulations and Safety

International Standards

The Codex Alimentarius Commission establishes international food standards for olive-pomace oils, defining olive-pomace oil as a blend of refined olive-pomace oil and virgin olive oils with a free acidity, expressed as oleic acid, not exceeding 1 gram per 100 grams for edible use.^[96] Labeling requirements mandate compliance with the General Standard for the Labelling of Prepackaged Foods (CXS 1-1985), including the product name that accurately reflects its composition, such as "olive-pomace oil," without using the term "olive oil," and declaration of any additives when used in food products.^[96] No additives are permitted in virgin olive oils, but refined pomace oils may incorporate permitted processing aids under Codex guidelines for fats and oils.^[96] Revisions to the standard (CXS 33-1981) are ongoing as of 2024, including updates to sections on composition and contaminants.^[97] European Union regulations under the amended Waste Framework Directive (EU) 2018/851 classify olive pomace as bio-waste and promote its recycling through separate collection, composting, or anaerobic digestion to achieve high environmental protection and recovery rates, with targets of at least 55% recycling of municipal waste by weight by 2025, 60% by 2030, and 65% by 2035; separate collection of bio-waste is mandatory, and new food waste reduction targets include a 30% per capita decrease at retail and consumer levels by 2027.^[98]^[99] For pomace-derived oils, extraction solvent residues, such as hexane, are limited to no more than 1 mg/kg in the final product to ensure safety, as specified in Directive 2009/32/EC on extraction solvents used in food processing.^[100] The ISO 22000 standard provides a framework for food safety management systems applicable to organizations handling pomace within the global food chain, from production to distribution, emphasizing hazard analysis, risk assessment, and prerequisite programs to ensure safe integration into food supply chains.^[101] Complementary ISO methods, such as ISO 12193 for lead determination, support testing for contaminants like heavy metals in olive-pomace oils, with limits aligned to international thresholds to prevent health risks.^[102] World Trade Organization (WTO) rules under the Agreement on the Application of Sanitary and Phytosanitary Measures (SPS Agreement) govern pomace exports by requiring that import restrictions be science-based, transparent, and non-discriminatory, allowing measures to protect human, animal, or plant health while facilitating trade, as seen in resolved disputes over pomace olive oil imports.^[103] Global certification for organic pomace products follows standards like the USDA National Organic Program (NOP), which verifies organic integrity from farm to processing, ensuring no prohibited substances and traceability for international trade.^[104]

National Regulations

In the European Union, national regulations for pomace often align with broader community standards but include localized implementations. In Italy, a major olive producer, the use of hexane as an extraction solvent in olive pomace oil production is governed by EU Directive 2009/32/EC, which establishes a maximum residue limit of 1 mg/kg in the final fat or oil product to ensure safety. This limit applies directly to refined olive pomace oil, helping to mitigate potential health risks from solvent residues in a country where olive processing generates significant pomace volumes. France, another key European producer, imposes strict appellation d'origine contrôlée (AOC) rules on pomace brandy, particularly for Marc de Bourgogne. Under these regulations, production must use pomace exclusively from Burgundy grapes, with distillation limited to a maximum alcohol strength of 72% by volume off the still, followed by aging for at least two years in oak barrels, and bottling at a minimum of 40% alcohol by volume to preserve regional authenticity and quality. In the United States, the Food and Drug Administration (FDA) affirms pectin extracted from apple pomace as generally recognized as safe (GRAS) under 21 CFR 184.1585 for use in human food applications, such as a dietary fiber source in baked goods, beverages, and supplements, based on its historical safe consumption.^[105] Apple pomace itself is used in food based on similarity to this GRAS ingredient. For agricultural reuse, the Environmental Protection Agency (EPA) provides guidelines for applying pomace-based organic amendments as fertilizers, recommending rates not exceeding 20 tons per hectare to avoid nutrient overload and maintain soil health, in line with broader nutrient management practices for composted materials.^[106] Canada's regulations, overseen by the Canadian Food Inspection Agency (CFIA), approve dehydrated apple pomace as a livestock feed ingredient under the Feeds Regulations, 2024, with standards requiring guarantees for minimum crude protein (4%), maximum moisture (12%), and maximum crude fiber (20%), but cautioning against use in poultry diets due to potential digestive issues; nutritional guidelines suggest a maximum inclusion rate of 15% in ruminant rations to optimize digestibility without nutritional imbalance.^[107] Imports of pomace are subject to CFIA restrictions on contaminated residues, prohibiting entry if pesticide or heavy metal levels exceed established tolerances to protect animal health and the food chain.^[108] In other nations, Australia enforces stringent quarantine rules through the Department of Agriculture, Fisheries and Forestry (DAFF), requiring import permits and treatments (e.g., fumigation or irradiation) for fruit pomace to mitigate biosecurity risks from pests and diseases, with non-compliance leading to refusal or destruction at the border.^[109] In China, the National Food Safety Standard GB 2760-2024 permits the use of pomace-derived ingredients, such as apple fiber, in foods for functions like thickening or stabilization in categories like bakery products and beverages, subject to safety and labeling requirements.^[110]
