Abstract
Abstract The food enzyme endo‐polygalacturonase (1,4‐α‐d‐galacturonan glycanohydrolase; EC 3.2.1.15) is produced with the non‐genetically modified Aspergillus tubingensis strain SPG 10‐1199 by Shin Nihon Chemical Co., Ltd. The food enzyme was considered free from viable cells of the production organism. It is intended to be used in seven food manufacturing processes. Since residual amounts of food enzyme–total organic solids (TOS) are removed in one process, dietary exposure was calculated for the remaining six food manufacturing processes. It was estimated to be up to 0.517 mg TOS/kg body weight (bw) per day in European populations. Genotoxicity tests did not indicate a safety concern. The systemic toxicity was assessed by means of a repeated dose 90‐day oral toxicity study in rats. The Panel identified a no observed adverse effect level of 1740 mg TOS/kg bw per day, the highest dose tested, which when compared with the estimated dietary exposure, resulted in a margin of exposure of at least 3366. A search for the homology of the amino acid sequence of the endo‐polygalacturonase to known allergens was made and matches with one food allergen and 12 respiratory allergens were found. The Panel considered that a risk of allergic reactions upon dietary exposure to this food enzyme cannot be excluded. 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.
