Production technology of dual-crop compound protein isolates

Abstract

The invention relates to a production technology of dual-crop compound protein isolates, which comprises the followings: low-temperature soybean meals (1) are prepared into soybean emulsion of acid sediment (14) through extraction and acid sediment procedures; peanut flour (21) can be prepared into peanut extractive and mixed emulsion (29) through an extraction procedure; the soybean emulsion of acid sediment (14) and the peanut extractive and mixed emulsion (29) are added into a neutralization tank (C) based on the proportion for mixing, stirring and confecting; the emulsions are prepared into neutralized solution (15) through a neutralization procedure; the neutralized solution (15) is prepared into enzyme solution (17) through an enzymolysis procedure; the enzyme solution (17) is prepared into flashing liquid (18) through a sterilization procedure; the flashing liquid (18) is prepared into compound protein isolates (19) with protein content more than or equal to 90% through a drying procedure and finally the compound protein isolates (19) enter warehouses after being packed and detected through packing and detecting procedures. The production technology features compact procedure linkage and complete device configuration, can fit the demand of scale serial production, promotes the increase of deep processing conversion rate and utilization factor of farm products and conduces to optimizing industrial structures and product structures of soybeans and peanuts to realize industrialization. The prepared product combines the characteristics of both soybean protein isolates and peanut protein isolates and has rich nutrition, wide application and high added value of products.

Description

technical field [0001] The invention relates to food processing technology, in particular to the processing technology of oil crop protein isolate. Background technique [0002] In addition to the traditional oil extraction, the further development and utilization of oil crops, the direct extraction of proteins contained in oil crops, and various utilizations have always been the research focus of the food industry. After long-term unremitting efforts, breakthrough progress has been made and it is moving towards industrial production. Such as the extraction of protein powder from soybeans and peanuts has been successful, some products have been put into use. For example, adding soybean protein powder to meat products and peanut protein powder to flour to make a variety of pastries have achieved good results and are gradually accepted by the general public. But there are also shortcomings, such as soybean protein has strong functionality, but the taste is slightly beany fla...

AI Technical Summary

Problems solved by technology

However, there are also shortcomings. For example, soybean protein has strong functionality, but the taste is slightly beany, which affects more comprehensive application; peanut protein has strong dispersibility, but poor functionality, and its application is also restricted.

If the advantages of the two oil crops can be combined to make a mixed protein isolate, the nutrition will be more comprehensive and the application will be wider. At present, there is no product and process for producing double crop mixed protein isolate.
