Abstract: 
The food enzyme glucan-1,4-alpha-glucosidase (4-alpha-d-glucan glucohydrolase; EC 3.2.1.3) is produced with the non-genetically modified Aspergillus niger strain DP-Azh100 by Genencor International B.V. It was considered free from viable cells of the production organism. The food enzyme is intended to be used in four food manufacturing processes. Since residual amounts of total organic solids (TOS) are removed in two processes, dietary exposure was calculated only for the two remaining processes. It was estimated to be up to 1.390 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 at the highest dose tested of 1000 mg TOS/kg bw per day, which when compared with the estimated dietary exposure, resulted in a margin of exposure of at least 719. A search for the homology of the amino acid sequence of the food enzyme to known allergens was made and one match to a respiratory allergen was found. Known sources of food allergens were used in the food enzyme manufacturing process. The Panel considered that the risk of allergic reactions upon dietary exposure to this food enzyme cannot be excluded, 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.
