Asparagus pea instant powder product and preparation method thereof

Abstract

The invention provides a preparation method of an asparagus pea instant powder product. The preparation method comprises the following steps: firstly carrying out water milling and alcohol precipitation, carrying out enzymolysis on the obtained hydrolysate, carrying out thin film evaporation to dryness, and then carrying out mixing with a mulberry leaf extract to obtain the product. The asparagus pea instant powder product fully utilizes proteins, polysaccharides and flavonoids in asparagus peas and overcomes the special beany flavor generated by the asparagus peas in traditional technical processes, so that the asparagus pea instant powder product is very suitable for diabetic patients to eat. The method can avoid the degradation of the polysaccharides under the conditions of high temperature and acid and alkali treatment, can adjust the contents of the polysaccharides in the product according to different demands, and can improve the yield of small peptides with high lysine contents by virtue of a mode of carrying out denaturation and then hydrolysis on the proteins.

Description

technical field [0001] The invention relates to a square bean instant powder product and a preparation method thereof, belonging to the technical field of food processing. Background technique [0002] Four-sided beans are also called winged beans, winged beans, four-cornered beans, four-twisted beans, carambola beans, tropical soybeans, dragon beans, emperor beans, fragrant dragon beans, etc. The pods are four-sided long cylinders with four corners, so they are called four-sided beans.

Problems solved by technology

[0010] Although the four-lens bean resource is quite abundant, the yield can be compared with that of soybean, and the nutritional content is better than that of soybean, but the above-mentioned literature shows that the research and product development in processing are quite weak, and the loss of nutritional content is serious during the processing process. The low added value leads to low prices of the square bean itself and processed products, which restricts the enthusiasm for planting and is unfavorable to the development of "agriculture, rural areas and farmers"
