The invention provides a specific compound
enzyme preparation for hard biscuit. The compound
enzyme preparation comprises the following components in percentage by weight: 10 to 20 percent of
neutral protease, 6 to 12 percent of
papain, 6 to 10 percent of hemicellulase, 2 to 4 percent of bacterium
alpha amylase, 1 to 4 percent of
fungus alpha amylase, and 56 to 69 percent of glucosum anhydricum. The specific compound
enzyme preparation has the following technical effects that 1) the preparation can be used for replacing chemical additive
sodium pyrosulfite by 100 percent, so that the
adverse effect by using the
sodium pyrosulfite can be eliminated, and the produced biscuit is healthier; 2) the quality of the biscuit can be remarkably promoted, and the produced biscuit has the characteristics of plump biscuit body, uniform color, golden bright surface, crisp taste, good dissolving property in the mouth, rich natural baking
flavor and the like; 3) when the biscuit is produced, the dough water addition can be reduced, and the biscuit baking time can be shortened, so that the production
energy consumption can be reduced, and better energy-saving and environmental friendliness are brought; and 4) the preparation has simple production process, convenience for use, and great practical application value.
