Dried soybean yoghurt and preparation method thereof

Abstract

The invention discloses dried soybean yoghurt and a preparation method thereof. The preparation method comprises the following steps: soaking selected soybeans in treated water, grinding the treated soybeans, boiling pulp, blending, homogenizing, cooling, adding bacteria strain, fermenting, wrapping and burying, performing spray drying, crushing, packaging and storing finished products at 0-60 DEG C. The dried soybean yoghurt prepared by using the preparation method adopts pure plant protein for fermentation, is free of cholesterol and saturated fatty acid, is beneficial for health and has various functions of helping digestion and maintaining intestinal health, preventing or treating diarrhea and astriction, alleviating lactose intolerance, prompting organism nutrient absorption, reducing cholesterol, reducing high blood pressure and the like. The dried soybean yoghurt prepared by using the preparation method has the advantages of high activity, small size and convenience in use. As the low-temperature spray drying is adopted, live lactic acid bacteria useful for human bodies in the dried soybean yoghurt can be maintained to the maximum extent, and the bacterium content is greater than 108CFU / ML. The dried soybean yoghurt can be constantly brewed and drunk, and is convenient to take.

Description

technical field [0001] The invention relates to a preparation method of a health care product, in particular to a soybean yoghurt powder and a preparation method thereof. Background technique [0002] Protein is the material basis of life, without protein there is no life. Therefore, it is a substance closely related to life and various forms of life activities. Every cell and every major part of the body has proteins involved. Protein accounts for 16%~20% of the body weight, that is, a 60kg adult has about 9.6~12kg of protein in his body. While animal protein food supplies protein to the human body, it also brings a large amount of cholesterol, fat and heat energy. Excessive cholesterol and fat lead to an increase in the incidence of "rich and noble diseases" such as high blood pressure, high blood fat, and heart disease, which brings great harm to human health. come great danger. [0003] With the improvement of living standards, people have turned from seeking food an...

Problems solved by technology

However, the shelf life of yogurt is short, and it is inconvenient to transport because the tissue state is in a semi-fluid state.

[0005] Spray drying is suitable for large-scale industrial production, but ordinary spray drying has a high heating intensity of raw materials and few viable bacteria.
