Problems solved by technology

[0014] Although the four-lens bean resource is quite abundant, the output is comparable to that of soybeans, and the nutritional content is comparable to that of soybeans, but the research and product development in processing are quite weak, and basically no products have been launched on the market, which restricts the enthusiasm for planting. The development of “Sannong” is unfavorable. In addition, high-quality protein and its hydrolyzate have been widely used in medicine, cosmetics, health products, food and feed additives, etc., which have been verified.

Abstract

The invention discloses a technology for producing winged bean protein peptide nutrient powder. The technology comprises the following steps of: soaking fresh winged beans into alkali liquor, breaking and peeling; pulping with water, regulating the pH value to be alkali, preserving the heat, sterilizing and filtering; and regulating the pH value to be acidic, standing, centrifuging, suspending with water, regulating the pH value to be slightly alkali, adding flavorzyme for hydrolysis, heating, preserving the heat, performing vacuum degassing treatment and spray drying, and thus obtaining the nutrient powder. By adopting the vacuum degassing treatment in the method, special beany flavor of the winged beans in the protein powder making process of the traditional craft is eliminated; meanwhile, the protein is subjected to protease denaturation treatment, so that the nutrient property and the function property of the protein are increased, and loss of the protein nutrient component of thewinged beans is avoided; and the technology is convenient for industrialized production and increases the additional value of winged bean processing.

Description

technical field [0001] The invention relates to the technical field of biological processing, in particular to a production process of kidney bean protein powder rich in protein peptides. Background technique [0002] The origin of the four-lens bean is in the tropics, and its seeds, roots, young pods, young leaves, and flowers are all edible; the vines and pod shells can be used as a feed with high protein, high nutrition and good palatability after drying and processing. Square beans are rich in protein, vitamins and minerals, and can be used as food crops, oil crops, new vegetables, feed, etc., and have great development potential and development value. It has been developed as a new high-protein food resource in many countries and regions. my country's artificial cultivation of square-lens beans has a history of hundreds of years, mainly distributed in low-latitude Hainan, Guangdong, Guangxi, Yunnan and other provinces (regions). [0003] The protein content of ripe fo...
