Description

technical field [0001] The invention relates to the technical field of food additives, in particular to a bread preservation enzyme preparation. Background technique [0002] Bread is a food made by grinding and heating five grains (usually wheat). Baked food made from wheat flour as the main raw material, yeast, eggs, oil, nuts, etc. Generally, during the storage process of bread, there will be problems such as quality decline, such as loss of luster on the skin, loss of aroma, reduction of moisture, retrogradation of starch in the crumb, hardening and slag loss, reduction of soluble starch, etc., also known as aging of bread. [0003] Flour contains 70-80% starch. During the baking process, starch gelatinization fills the gluten skeleton and forms the structure of bread. After the gelatinized starch is cooled, it will age in different degrees with the prolongation of storage time, that is, the retrogradation of starch (also known as aging). The aging of starch leads to ...
