Enzymes

Enzymes are bought by activity rather than by weight, and an activity figure only means something with its assay attached, since suppliers use different unit definitions and different substrates. A declared hundred thousand units per gram says nothing without the method, so comparing two quotations means converting both onto one basis or testing them side by side.

The category then splits by source and by working conditions. Transglutaminase, Protease, Amylase and Nattokinase are made by fermentation, and Lysozyme is also recovered from egg white, which makes it an allergen question. Bromelain and Papain are plant proteases from pineapple stem and papaya latex. Each has an optimum pH and temperature band and a point at which it denatures, so an enzyme that performs in a cold brine may do nothing in a hot process. Adhesives For Restructured Meat are transglutaminase already blended with a carrier at a fixed activity.
