preparation example Construction

[0027] The preparation method of a kind of fermented bean curd according to the present invention adopts black soybeans as the main raw material of beans, and makes fermented bean curd according to the conventional process including soaking, refining, boiling, filtering, ordering, pressing, dicing, pre-processing Fermentation, pickling, post-fermentation and other processes, the specific operation steps are as follows:

[0028] 1. Screening: The black beans that have passed the inspection are screened by an electric vibrating screen.

[0029] 2. Soaking: Put the black beans into the pool for soaking. Water: dried beans = 3.5:1. Soak at room temperature for 6-12 hours.

[0030] 3. Grinding beans: add water to the soaked black beans for machine grinding, and the fineness is 8-10um.

[0031] 4. Boiling: Boil the ground black soybean paste, heat to 95-100°C, and keep warm for 5 minutes.

[0032] 5. Filtration: filter the boiled pulp. After 100 mesh nylon silk cloth. The bean...

Abstract

The invention relates a method for producing preserved beancurd, which is characterized in that black beans are used as main raw materials and the product is produced by using a preserved beancurd process, compared with a common process, the coagulant used for shaping beancurd in the slurry curdling process according to the invention is 1% acid water; in the primary cultivation and fermentation process, the low-temperature bacterium cultivation process is used, the room temperature is controlled at 20-24 DEG C all around the year, the cultivation time is 36-40 hours; in the secondary fermentation process of the post production process, the concentration of the recombined salt wine is lower than the common concentration, so the content of the protein and aminoacid in the produced black preserved beancurd is higher, and the product has salt-fragrant, fresh sweet and soft glutinous mouth feelings.

Description

technical field [0001] The invention relates to a preparation method of fermented bean curd. Background technique [0002] The production history of domestic fermented bean curd is very long. The state stipulates that there are relatively high quality standards and inspection standards for the quality of fermented bean curd. In terms of fermented bean curd production technology, fermented bean curd has changed from seasonal production to annual production. On the one hand, the manufacturers have always used soybean or meal as the main raw material to produce fermented bean curd. [0003] The process of brewing fermented bean curd with beans as raw materials is mainly a process of protein change. [0004] The traditional process of making fermented bean curd is as follows: Soybeans→→screening→→soaking→→grinding beans→→boiling→→filtering→→pointing pulp (adding acid water in the process)→→squatting brain→→pressing embryos→→cutting Block→→draining→→cultivation and fermentation...
