Question

Which is not application of the use of lactase in industries?

(a) Production of ice-creams

(b) Production of sweetened flavored milk

(c) Meat tenderization

(d) Production of condensed milk

This question was addressed to me during an internship interview.

My question comes from Large Scale Use of Enzyme topic in chapter Large Scale Use of Enzyme in Solution of Enzyme Technology

Answer 1

Right option is (c) Meat tenderization

The best I can explain: Lactase is a β-galactosidase enzyme which hydrolyzes lactose to galactose and glucose Meat tenderization is done by papain which is a proteolytic enzyme, and not lactose. Lactose is used in the production ice-creams, sweetened flavored milk and condensed milk.
