Problems solved by technology

[0005] However, in addition to lactic acid, traditional kefir milk also has high acetic acid content, high acidity, and irritating taste, which is difficult to be accepted by most consumers.
At the same time, the acetic acid bacteria and lactic acid bacteria in kefir will further produce acid during the storage period of the product, the post-acidification is very serious, and the shelf life of the product is short. These problems must be solved in order to realize the industrialization of kefir milk

Abstract

The present invention discloses a kefir acid soymilk and a production method thereof. The kefir acid soymilk consists of soybean milk and animal milk which are matched to take effect of the complementation of protein nutrition. The acid soymilk which is produced by fermenting the soybean milk through microorganism not only has the nutrient efficacy of the soybean, but the microorganism fermenting process is also good for eliminating anti-nutritional factors in the soybean, thus improving the nutrient and healthy efficacy on the soybean milk. The kefir acid soymilk has smooth taste, proper acidity, soft flavor and intense bee wine fragrance, besides, aromatic carbonyl compound, phenolic acid substance and the like in the soybean take certain restraining effect on partial microorganism in the kefir. Compared with the traditional kefir, the kefir acid soymilk has the low excitation of the taste, is fit for the taste of most people and reduces the post acidification during storage greatly, and the shelf life is prolonged. The preparation method has low cost, simple operation and high feasibility and has good application prospect.

Description

technical field [0001] The invention relates to kefir yoghurt, in particular to kefir yoghurt produced by kefir fermented soy milk and a production method thereof. Background technique [0002] Soybean is a traditional healthy food, rich in protein, accounting for about 40% of the dry weight of soybeans, and the content of essential amino acids is very rich. Except for the low content of methionine and cysteine, the rest of the essential amino acids generally meet or exceed the World Health Organization recommended demand level. Some physiologically active substances contained in soybeans have good health effects, such as a large amount of soybean oligosaccharides such as stachyose and raffinose, which can promote the proliferation of bifidobacteria in the intestinal tract and are good prebiotics; soybean saponins It can promote the metabolism of cholesterol and fat in the human body, reduce the generation of oxidized lipids, delay aging, inhibit goiter, and has anti-inflam...
