Method for preparing coffee-mate by using aqueous enzymatic emulsion

Abstract

The invention discloses a method for preparing coffee-mate by using aqueous enzymatic emulsion. The method for preparing the coffee-mate by using the aqueous enzymatic emulsion comprises the following steps: (1), washing soybeans, pressing the washed soybeans into tablets, carrying out extrusion and expansion pre-treatments so as to obtain puffed materials, and then, mixing the puffed materials with water so as to obtain a mixed solution; (2), adjusting the temperature and the pH value of the mixed solution, adding alkaline protease and flavor protease so as to carry out enzymatic hydrolysis, adding enzymes to carry out enzymatic hydrolysis so as to obtain an enzymatic hydrolysate, deactivating the enzymes of the enzymatic hydrolysate, and then, carrying out centrifugal separation so as to obtain a protein solution, an emulsion and residues; and (3), adding auxiliary materials into the emulsion, carrying out emulsification reaction, performing high-pressure homogenization treatment, and then, carrying out spray-drying, so that novel soybean powder lipid with high oil content but without oil leakage is prepared. The natural emulsion formed while production of the soybean protein liquid during enzymatic hydrolysis of the soybeans is utilized as a good raw material for preparing the soybean coffee-mate; moreover, the wall materials, including beta-cyclodextrin, isolated soy protein and compounded emulsions, compounded antioxidants and sodium caseinate are added, so that the soybean coffee-mate with relatively good qualities is obtained.

Description

technical field [0001] The invention belongs to the processing technology of vegetable oil application, and mainly relates to a method for preparing coffee mate by extracting soybean oil emulsion by an aqueous enzymatic method. Background technique [0002] As a new "green, environmentally friendly and healthy" oil extraction technology, the aqueous enzymatic method (EAEP) technology can efficiently prepare other protein products while extracting oil. Compared with the traditional process, the water enzymatic oil extraction technology has significant advantages in terms of energy consumption, environment, safety and sanitation. A novel coffee mate can be prepared by preparing the emulsion of the soymilk protein powder from the protein component. At present, the traditional preparation method of coffee mate is to use high-purity wall material glue substances such as gum arabic and carrageenan, polysaccharides such as chitosan, starch substances such as maltocyclodextrin, cel...
