Beta D Galactosidase

Beta-D-galactosidase is an enzyme that breaks down lactose, a sugar found in milk. It is naturally produced by various organisms, including bacteria and fungi, and can be produced commercially through fermentation processes using selected microbial strains. The enzyme is often purified from these microbial sources for use in food production.

Beta-D-galactosidase is primarily used in the food industry to reduce or eliminate lactose in dairy products, making them suitable for lactose-intolerant individuals. It is added to products like milk, ice cream, and yoghurt to pre-digest the lactose. It can also be used in the production of other food items where lactose breakdown is beneficial.

Beta-D-galactosidase is not listed as an authorised food additive on the Register of Food Additive Authorisations in Great Britain. It is generally considered safe as it is a naturally occurring enzyme involved in digestion. Regulatory bodies like EFSA have evaluated enzymes used as processing aids, and while specific evaluations for beta-D-galactosidase as a food additive are not prominent, its function is well-understood. There are no significant controversies surrounding its use at typical levels.
