Safety evaluation of the food enzyme bacillolysin from the non-genetically modified Bacillus amyloliquefaciens strain HPN 131

The food enzyme bacillolysin (EC 3.4.24.28) is produced with the non-genetically modified Bacillus amyloliquefaciens strain HPN 131 by ENMEX SA de CV. The production strain qualifies for the qualified presumption of safety (QPS) approach to safety assessment. The food enzyme under assessment is intended to be used in seven food manufacturing processes: processing of cereals and other grains for the production of baked products, brewed products and distilled alcohol; processing of dairy products for the production of modified milk proteins; processing of meat and fish products for the production of protein hydrolysates; processing of plant- and fungal-derived products for the production of protein hydrolysates; processing of yeasts and yeast products. Since residual amounts of total organic solids (TOS) are not carried over to distilled alcohol, a dietary exposure was estimated only for the remaining six food manufacturing processes. Exposure was estimated to be up to 8.302 mg TOS/kg body weight (bw) per day in European populations. As the production strain qualifies for the QPS status and no issue of concern arose from the production process of the food enzyme, the Panel considered that no toxicological studies other than the assessment of allergenicity were necessary. A search for the similarity of the amino acid sequence of the food enzyme to known allergens was made and no matches were found. The Panel considered that the risk of allergic reactions by dietary exposure cannot be excluded (except for distilled alcohol production), but the likelihood is low. Based on the data provided, the Panel concluded that this food enzyme does not give rise to safety concerns under the intended conditions of use.

Automated summary

This study assessed the safety of a food enzyme produced by a non-genetically modified strain and used in seven food production processes. The results showed that the food enzyme does not pose safety concerns under the intended conditions of use. Although there is a low risk of allergic reactions from dietary exposure, it is unlikely.
