What are industrial enzymes?
Food enzymes are specialized proteins that catalyze specific biochemical reactions in food processing, enabling transformations that would otherwise require chemical treatments or be difficult to achieve. Common food enzymes include amylase (breaks down starch), protease (breaks down protein), lipase (breaks down fats), lactase (breaks down lactose), rennet (coagulates milk protein), and transglutaminase (cross-links proteins). Enzymes have been used in food production for millennia — cheesemaking, bread baking, and brewing all fundamentally rely on enzymatic activity.
27,194 products in our database contain industrial enzymes. 9,692 of them (36%) are Level 4, the most processed of our four levels.
Which foods contain industrial enzymes?
Enzymes are used in bread and baked goods, cheese and dairy products, beer and wine, fruit juices, high fructose corn syrup production, meat tenderizers, lactose-free dairy products, restructured meat products, and many processed foods where they may not appear on the ingredient label due to processing aid exemptions.

Industrial Enzymes can appear in ingredient lists under several names. If you see any of the following, this is the ingredient family you are looking at:
Function
Food enzymes accelerate specific chemical reactions during food processing to achieve desired transformations in texture, flavor, appearance, and nutritional properties. Amylases convert starches to sugars for fermentation and browning. Proteases tenderize meat and clarify beverages. Lipases develop flavor in cheeses. Pectinases clarify fruit juices by breaking down pectin. Transglutaminase bonds proteins together to restructure meat products. Many enzymes are denatured (inactivated) by heat during cooking or processing, meaning they are not active in the final product.
Sources
Food enzymes are produced through microbial fermentation using bacteria (Bacillus species), fungi (Aspergillus species), or yeasts that have been selected or genetically engineered to produce high yields of specific enzymes. Traditional enzyme sources include animal tissues (pepsin from stomach lining, rennet from calf stomachs) and plant materials (papain from papaya, bromelain from pineapple). Modern enzyme production has largely shifted to microbial fermentation, which provides consistent quality, scalable production, and vegetarian-compatible alternatives to animal-derived enzymes.
Health considerations
Most food enzymes are denatured during processing and are no longer active in the finished food product. Enzymes are proteins and are digested like other dietary proteins when consumed. Some enzyme preparations may contain trace amounts of the production organism or its metabolites, though these are controlled through purification processes. Individuals with allergies to specific enzyme sources (e.g., papaya for papain) should be aware of enzyme origins.
This information is for educational purposes only and does not constitute medical advice.
Regulatory
In the US, many food enzymes are classified as GRAS or approved as food additives. The FDA does not require enzymes used as processing aids (those inactivated or removed during processing) to be declared on ingredient labels, which means many enzymatically processed foods do not list enzymes among their ingredients. The EU has established a more comprehensive regulatory framework for food enzymes under Regulation EC 1332/2008, requiring safety evaluation and authorization of all food enzymes.
