Abstract

A frozen dough prepared by the antifreezing yeast treated by glycerine for making bread is prepared through dispersing the active dry yeast in water, adding glycerine, stirring, storage, centrifugal treating, filtering adding flour and egg, stirring, adding shortening oil, stirring, laying aside, kneading, laying aside, shaping and freezing.

Description

technical field [0001] The invention relates to a method for producing freeze-resistant frozen bread dough by treating yeast with glycerin, specifically, pretreating ordinary yeast with glycerin to improve its frost resistance in a frozen dough system, which belongs to the technical field of food processing . Background technique [0002] Today, with the rapid development of refrigeration technology, frozen dough is gradually accepted by the baking industry due to its convenience and large-scale production. Frozen dough, that is, the application of freezing and refrigerating technology, after the raw materials are weighed, mixed with water to form a dough, the dough is frozen, and then refrigerated; when used, it only needs to be thawed, put into the oven and baked to obtain fresh baked food products. This not only realizes the "freshly baked and sold" can provide consumers with fresh products at any time, but also greatly reduces the economic losses caused by the unstable ...
