Description
Technical Field
The utility model relates to a soybean protein processing technology field, concretely relates to device of functional concentrated protein of slice soybean high temperature dregs of rice preparation.
Background
The low-temperature soybean meal is prepared from non-transgenic soybeans by low-temperature crushing, peeling and low-temperature desolventizing, has the advantages of white color and high NSI (non-nutritive value), and contains beany flavor and anti-nutritional factors due to the characteristics of the processing technology. The beany flavor is mainly formed because lipoxygenase in the soybeans is activated by oxygen and water when the soybeans are crushed, and multivalent unsaturated fatty acids such as linoleic acid and linolenic acid in the soybeans are oxidized to generate hydroperoxide and then degraded into various volatile compounds such as micromolecular alcohol, aldehyde, ketone, acid, amine and the like with different degrees of peculiar smells. The trypsin inhibitor is a main anti-nutritional factor in the soybean protein isolate, can chemically react with various proteases, reduces digestion, absorption and utilization of proteins, causes growth arrest, pancreatic hyperplasia, hypertrophy and the like, oligosaccharides represented by raffinose and stachyose are also important anti-nutritional factors, and the raffinose and stachyose cannot be digested by digestive enzymes, so that flatulence is caused.
The traditional functional soybean protein concentrate takes low-temperature meal as a raw material, and the following two preparation methods are adopted:
the first is alcohol method protein concentration and modification: by utilizing the principle that the soybean protein is in an isoelectric point state in 70% ethanol aqueous solution, the protein is coagulated and insoluble in the ethanol aqueous solution, and substances such as sucrose, oligosaccharide, pigment, fishy smell and the like are dissolved in the ethanol aqueous solution, the substances such as the sucrose, the oligosaccharide, the pigment, the fishy smell and the like in the low-temperature meal are extracted by the 70% ethanol aqueous solution, and the soybean protein concentrate with dry basis protein of more than or equal to 65% is obtained through drying and desolventizing, and the soybean protein concentrate is further crushed, modified by adding water, sterilized and spray-dried to obtain the functional protein concentrate. The functional concentrated protein contains sodium salt and ethanol residue because the ethanol aqueous solution is adopted in the extraction process and NaOH is added in the modification process, and the functional concentrated protein cannot be applied to infant food and the like.
The second method is acid method protein concentration and modification: based on the principle that the soybean protein is in an isoelectric point state in an acidic aqueous solution with a pH value of 4.5, the protein is coagulated and is not dissolved in the acidic aqueous solution, and substances such as sucrose, oligosaccharide and the like are dissolved in the acidic aqueous solution, the substances such as sucrose, oligosaccharide and the like in the low-temperature meal are extracted by a hydrochloric acid aqueous solution with a pH value of 4.5, a soybean concentrated protein solution with dry basis protein of more than or equal to 65 percent is obtained by centrifugal separation, water is added for tempering, naOH is added for regulating the pH value, and the functional concentrated protein is obtained by modification, sterilization and spray drying. The functional concentrated protein has beany flavor because fishy substances are not dissolved in an acidic aqueous solution in the extraction process, and the functional concentrated protein contains a large amount of sodium salt due to the addition of hydrochloric acid and NaOH in the extraction and modification processes, so that the functional concentrated protein cannot be applied to health foods such as infant food.
The functional soybean protein concentrate is a main development direction, some patent and literature reports exist, the mainstream modification technology is physical modification such as heating, pressurizing and the like, the technology is modified for a soybean protein concentrate product, the emphasis is single and is relatively simple, the sheet is not, the targeted research is not carried out from raw materials and an extraction process, the emulsifying functionality is improved, but the fishy smell component of the product or the residue of an additive in the processing process cannot be solved, and the green and organic health processing concept is violated.
