Food Enzyme From Modified Microbe Deemed Safe
European regulators find the enzyme poses no safety concern at estimated dietary exposure levels, though allergic reactions cannot be fully ruled out.
Updated on Nov. 6, 2026 in Nutrition
The European Food Safety Authority's scientific panel concluded that glucan endo-1,3-β-D-glucosidase, a food enzyme produced with a genetically modified Streptomyces violaceoruber strain, does not raise safety concerns. The enzyme is intended for use in two food manufacturing processes, with the assessment covering dietary exposure in European populations.
Why it matters
Food enzymes used in manufacturing are not always visible to consumers, so independent safety evaluations determine what ends up in processed foods. This assessment addresses both the genetic modification used to produce the enzyme and the enzyme itself, which is relevant to anyone interested in how processed food ingredients are regulated.
The assessment relied on a 90-day repeated dose oral toxicity study in rats, genotoxicity tests, and a homology search of the enzyme's amino acid sequence against known allergens, which found no match. The margin of exposure of at least 79,417 is derived from animal data and an exposure estimate, not from human trials.
The players
European Food Safety Authority
The EU agency that provides independent scientific advice on food and feed safety, including evaluations of food enzymes.
Nagase (Europa) GmbH
A European subsidiary of Japanese chemical company Nagase, which produces enzymes and other specialty ingredients for food and industrial use.
The details
The enzyme is produced by fermenting the genetically modified Streptomyces violaceoruber strain pGlu, a process carried out by Nagase (Europa) GmbH. The finished enzyme is free from viable cells of the production organism and its DNA, so residual microbial material is not expected in the product. Toxicity was assessed in rats over 90 days, with no adverse effects observed even at the highest dose tested, and genotoxicity tests raised no concern.

Health Landscape
Food enzymes are assessed under EU Regulation (EC) No 1332/2008, which requires safety evaluation before authorization for food use. This opinion sits within that framework and addresses the growing role of enzymes produced by genetically modified microorganisms in processed food manufacturing.
Most consumers will not encounter this enzyme on a label, since food enzymes used in processing are often not declared on packaging. The assessment supports continued use in the two food processes covered, but anyone with concerns about allergies or genetically modified ingredients may wish to discuss them with a physician or dietitian.
The takeaway
Independent safety assessments of food enzymes, including those made with genetic modification, are designed to answer questions about toxicity and allergenicity before ingredients reach the market. People with known food allergies or specific dietary concerns should discuss ingredient questions with a healthcare professional.
