Abstract The food enzyme considered in this opinion is a peroxidase (hydrogen‐peroxide oxidoreductase; EC 1.11.1.7) obtained from hulls of soybeans (Glycine max) by the company Kerry Ingredients & Flavours. The compositional data provided were considered sufficient. The manufacturing process did not raise safety concerns. The enzyme is intended to be used in baking processes. Based on the maximum recommended use level, dietary exposure to the food enzyme total organic solids (TOS) was estimated on the basis of individual data from the EFSA Comprehensive European Food Consumption Database. This exposure estimate is lower than the exposure to the fraction of soybean comparable to the food enzyme TOS resulting from the consumption of whole soybean‐derived foods by roughly an order of magnitude. As the food enzyme is derived from edible parts of soybean, in line with the requirements of the guidance document on food enzyme assessment, the Panel concluded that the provision of toxicological data was unnecessary. The potential allergenicity was evaluated by searching for similarity between the amino acid sequence of soybean peroxidase retrieved from the database Uniprot and the sequences of known food allergens; no match was found. Peroxidase from soybean hulls is not listed as an allergen in allergen databases. However, several soybean‐ and soybean hull proteins are known to be respiratory or food allergens. Based on the origin of the food enzyme from edible parts of soybean, the enzyme manufacturing process, the compositional and biochemical data provided, and the dietary exposure assessment, the Panel concluded that this food enzyme does not give rise to safety concerns under the intended conditions of use. However, the Panel noted that this food enzyme may contain allergenic soybean proteins, thus, adverse reactions in susceptible soybean‐allergic individuals cannot be ruled out.
