  • Single-dough cookies having storage stable texture
    Patent number: 4344969
    Abstract: Incorporation of a carbohydrase into cookie dough provides, via a special baking process, a cookie having a storage stable texture which emulates that of freshly baked, home-style, drop-type cookies. The process for making these cookies involves (1) retarding enzyme activity in the finished dough before baking; (2) deactivating the enzyme in a portion of the cookie, preferably the surface; (3) activating the remainder of the enzyme; (4) allowing the remaining active enzyme to operate on the carbohydrates in the cookie; and (5) final baking.
