Problems solved by technology

Whether it is the traditional method or the method disclosed by the patent CN1483345, there is a key problem in the production process that affects the fermentation process and quality - the fermentation cycle is too long, so a large amount of salt must be added to prevent the green body from corruption during fermentation go bad
Patent CN1698465 adopts enzymatic fermentation, which is improved to a certain extent compared with the natural fermentation of soup in traditional fermentation, but the multiple extraction process of enzyme liquid brings inconvenience to the industrialized production of fermented bean curd

Abstract

A method for preparing low-salt preserved bean curd comprises following steps: (1) sterilizing the bean curd prepared from soybean material and cooling to room temperature; (2) inoculating mold and fermenting for 24 to 48 hours; (3) adding an enzyme preparation to promote maturation, fermenting at 40 to 55 DEG C for 5 to 7 days; and (4) blending, properly packaging and sterilizing after maturation of the preserved bean curd to obtain low-salt preserved bean curd paste or pieces. The method shortens the preparation cycle of preserved bean curd, improves the product quality, and lowers the salt content in the preserved bean curd product, thus establishing the foundation for the quality improvement of conventional preserved bean curd and the modern industrial production.

Description

technical field [0001] The invention relates to the field of food, more specifically, a method for rapidly preparing low-salt fermented bean curd by using soybeans and their products as raw materials and adding specific molds and enzyme preparations / lactic acid bacteria through a fermentation method. Background technique [0002] Fermented bean curd is a soybean fermented product with Chinese characteristics. Fermented bean curd has the characteristics of rich nutrition, fine and smooth texture, delicious taste and attractive appetite. It is a favorite appetizer and condiment. In Europe and the United States, fermented bean curd is called Chinese-cheese because of its texture similar to soft cheese. [0003] The traditional preparation method is to use soybeans as raw materials, solidify and make tofu, and then add mold to ferment block food. The existing defect is that the fermentation cycle is long and it is easy to spoil. [0004] In order to meet the needs of antisepsis...
