Problems solved by technology

[0004] Aiming at the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is: the existing black soybean resource utilization degree is not high, fermented soya bean products are mostly fermented with a single bacterium and have a single taste, and fermented soya bean is easily infected with miscellaneous bacteria and products during the preparation process of soya bean. Taste and safety quality are difficult to control the technical problem, and provide a kind of preparation method of bacteria-fermented black soya bean tempeh with high safety, multi-level taste and richer nutrition

Abstract

The invention provides a preparation method of bacterial fermentation type fermented black soybeans. The method comprises the following steps: by taking black soybeans as raw materials, crushing, drying, swelling, steaming, inoculating with bacteria and fermenting, washing yeast, flavoring, and sterilizing, wherein in the bacterial fermentation, a compound bacterial fermentation agent consisting of bacillus subtilis RH3519 and micrococcus luteus is used for fermenting to obtain the bacterial fermentation type fermented black soybeans. The fermented black soybeans contain a plurality of types of amino acids, are rich in nutrients and delicious and fragrant in flavor and have layering; and the prepared fermented black soybeans do not contain pathogenic bacteria and harmful bacteria, thus being high in safety performance.

Description

technical field [0001] The invention belongs to the technical field of soybean meal, and in particular relates to a preparation method of bacterial fermented black soybean soybean meal. Background technique [0002] Black soybean is a leguminous plant soybean, which has the characteristics of high protein content and low calorie, and its vitamins and iron substances have high medicinal value. It is a good nourishing product in traditional Chinese medicine. There are many medicinal values ​​of wind and heat, blood circulation and detoxification. At present, black beans are mainly used as raw materials for cooking, or there are only black soybean milk products made from black beans. There are few other black soybean deep-processed foods, and the degree of resource utilization is not high. high. [0003] Douchi originated in my country and is a fermented bean food. Most of the existing Douchi products use soybeans as raw materials, and there are few Douchi products made from o...
