Problems solved by technology

However, the film-forming property of maltodextrin is not very good. When the water evaporates rapidly during the spray drying process, the self-healing ability of maltodextrin is poor, so that the pores caused by the rapid evaporation of water will remain on the surface of the product particles, and the surface of the product particles will be rough. , the product particles are not spherical, etc.

Abstract

The present invention discloses a preparation method of a high oil containing soybean powdered oil and belongs to food processing technology. The method comprises the following steps: (1) soybeans are cleaned and crushed, the crushed soybeans are sieved to obtain soybean powder, the soybean powder is mixed with water to form a mixed liquid, an alkaline protease enzyme is added into the mixed liquid to conduct enzymolysis, and the enzymolyzed mixed liquid is centrifuged to obtain a liquid phase and a solid phase; (2) an emulsifier phospholipid and a wall material maltodextrin are added into the liquid phase to conduct emulsifying treatment; and (3) the emulsified liquid is subjected to high pressure homogenization process to obtain highly stable emulsion and then the emulsion is spray-dried to obtain the high oil containing soybean powdered oil. The technology is simple, the operation is safe, and the cost is low. The natural emulsion formed in the enzymolysis of soybeans can be used as a good raw material to prepare soybean powdered oil. Then an appropriate amount of phospholipids and maltodextrin are added in the preparation method. The prepared soybean powdered oil is good in quality, high in oil amount, free of oil leakage, and has broad application prospects.

Description

technical field [0001] The invention belongs to food processing technology, and mainly relates to a preparation method of high oil content soybean powder oil. Background technique [0002] Aqueous enzymatic oil extraction (EAEP) technology is an emerging "green and environmentally friendly" oil extraction technology. It can efficiently recover other valuable components in oil while extracting oil. It is called "a kind of oil Compared with the traditional process, the water enzymatic oil extraction technology has significant advantages in terms of energy consumption, environment, safety and sanitation. However, in the process of extracting soybean oil by aqueous enzymatic method, due to the emulsification of protein and oil, the yield of free oil is low, and the protein is not easy to separate. At present, the traditional preparation method of powdered oil is to use high-purity wall materials such as gums such as gum arabic and carrageenan, polysaccharides such as chitosan, ...
