Enzymes used for animal feed and agriculture

These biocatalysts are designed for use in animal feeds or in agriculture-related applications such as silage production. These enzymes are used as direct and indirect feed additives. The choice of the enzyme is dependent upon the feed ration and the species.

Papain: A natural protease from papaya

Enzymes used for animal feed

Papain is a sulfhydryl protease extracted from the water-soluble portion of the latex of the fruit of Carica Papaya. It is a versatile protease that will rapidly hydrolyze a variety of proteins over a wide range of conditions. Our papain is a vegetarian and vegan-friendly protease and is non-GMO, as well as Kosher (Kof-K) and Halal (IFANCA) certified.

Papain has been used as a digestive aid for vegetable and other protein sources for over 60 years. It is particularly effective in monogastrics (poultry broilers and layers, and swine).

EDC is the only producer of papain in the western hemisphere. At our factory in Scranton, Pennsylvania, we produce standardized papain powders and liquids, as well as unstandardized concentrates. We also produce a no sulfite added papain that is OMRI listed for use in organic animal feeds.

EDC's papain products include:

Papain that is processed without the use of sulfites. The papaya latex in this product has been processed without the addition of sodium metabisulfite. This results in papain with substantially reduced levels of SO2.

This product contains only the botanical enzymes and has no other ingredients. It has earned an OMRI Listed® certification for use in organic Animal Feed.

A concentrated papain powder.

Liquid papain, standardized to activities of 100 and 200TU/mg.

LIQUIPANOL® RS 100 and RS 400
Liquid papain that is processed without the use of sulfites Liquid papain, standardized to activities of 100 and 400TU/mg. These products have earned OMRI listed® certifications, which means that it may be used in certified organic operations or food processing under the USDA National Organic Program.

Derived from Aspergillus niger, this protease has a pH optimum of 2.5 - 3.5.

Activity assays: Spectrophotometric Acid Protease (SAP).

This is a neutral protease derived from Bacillus licheniformis. (formerly B. subtilis) that has optimum activity from pH 5.5-8 and contains no/very low amylase side activity.

Activity assays: Protease Assay (PC)

A food-grade fungal alpha-amylase enzyme produced from Aspergillus oryzae that breaks down gelatinized starch to dextrins and maltose. Prolonged action results in the formation of large amounts of maltose. It is available in liquid, granulated and powder form as well as in a range of activities.

Activity assays: Modified SKB method (Sandstedt, Kneen, and Blish, Cereal Chemistry 16:172, 1939)

A powdered food grade enzyme preparation derived from a non-GMO strain of Bacillus amyloliquifaciens (formerly Bacillus subtilis), which contains high levels of a moderately heat stable alpha-amylase, with neutral protease, as a side.

Activity assays: Reference Amylase Unit (RAU)

A highly stable thermostable alpha-amylase enzyme liquid preparation derived from Bacillus licheniformis. This product is also available as a dry product on a custom basis. It helps release beneficial peptides and amino acids for improved growth rates/feed conversion ratios. Optimal activity occurs at 198°F.

Activity assays: Reference Amylase Unit (RAU)

A blend of alpha-amylases and proteases derived from Aspergillus oryzae and Bacillus amyloliquefaciens (formerly B. subtilis). This product also includes β-glucanases, as well as other size activities. This product is designed for use in silage inoculants, compost additives and in animal feeds. The alpha-amylases help to convert starches to readily fermentable water-soluble sugars and polysaccharides. The protease hydrolyzes protein to peptides and amino acids.

Activity assays: Reference Amylase Unit (RAU), Modified SKB method (Sandstedt, Kneen, and Blish, Cereal Chemistry 16:172, 1939) and Protease Assay (PC)

Xylanases S Concentrate is our highest xylanase activity product. It is a food grade enzyme preparation from a non-GMO strain of Trichoderma longibrachiatum (formerly T. reesei), containing xylanase as its principal activity. It also contains β-glucanase, galactomannanase, and cellulase, and has very little protease activity.

Activity assays: Xylanase Units (BXU)

A powdered food-grade cellulase preparation derived from a non-GMO strain of Trichoderma longibrachiatum (formally T. reesei) for use in animal feed. This product contains very high levels of endo-cellulase activity with a high cellulose-binding domain for hydrolysis of plant materials. It also contains significant amounts of β-glucanase, xylanase, and protease.

Activity assays: Endo Cellulase Units (ECU)

Proprietary blend of enzymes for equine.



A food-grade enzyme derived from a non-GMO Strain of Aspergillus niger. It is a high activity material. The enzyme will hydrolyze fats and oils most commonly at the 1, 3 positions. This product is heat stable and is stable over a broad pH range, work up to a pH of 10.
