Abstract
The present invention relates to a soybean deep-processing technique, in particular, said invention adopts a membrane method to extract soybean protein peptide and relates to a process for deep-processing its by-product. Said invention adopts the procedures of low-temperature soaking soybean cake in alkaline liquor, separation, ultrafiltering and resin adsorption to produce soybean protein peptide and by-product of soybean separation protein, soybean isoflavone, soybean saponin and soybean oligosaccharide.
Description
Technical field
The present invention relates to a kind of soybean deep processing technology field.
Background technology
Contain abundant high-quality protein in the soybean, comprising necessary eight seed amino acids of human body.At present, China existing soybean protein processing enterprise, the soy protein products of using traditional albumen processing technology production is functional relatively poor as gelation, emulsifying property, oil absorbency, water-retentivity, solvability, foaminess and froth stability etc., can't satisfy the needs of foodstuffs industry and producing high-grade food, force some large-scale meat product enterprises to have to use the soybean protein of import for the quality product that guarantees self, and, there is the protein peptide of functional performance can only dependence on import to some.
Summary of the invention
The purpose of this invention is to provide a kind of soy protein products rational membrane process for extracting soybean protein peptide of functional technology preferably and technique of deep processing byproduct thereof.
Membrane process for extracting soybean protein peptide and technique of deep processing byproduct thereof is characterized in that this technology may further comprise the steps:
1) the low temperature soybean meal was through sig water lixiviate 10-20 hour, and the alkali lye solid-liquid ratio is weight percentage 1: 10-20, pH value is 7.5-9, utilize whizzer to isolate bean dregs after the immersion after, utilize the polysulfone membrane ultrafiltration, separating whey solution and protein solution;
2) protein solution is carried out temperature 105-115 ℃, the instantaneous sterilization of time 3-5 second, after the sterilization protein solution is homogenized;
3) protein solution behind the homogeneous is concentrated, spraying drying promptly obtains the finished product soybean protein isolate;
4) protein solution behind the homogeneous is added protease hydrolysis, hydrolysis 10 hours utilizes the polysulfone membrane ultrafiltration again after the hydrolysis, and permeate is concentrated, and drying promptly obtains soybean protein peptide;
5) utilize macroporous resin to adsorb the whey solution in the step 1), adsorb the soybean isoflavones composition in the whey solution, utilize 70% ethanolic soln that macroporous resin is carried out wash-out again, obtain soybean isoflavones solution, promptly obtain soybean isoflavones after drying;
6) with the whey solution of the resin absorption of deviating from the soybean isoflavones composition in the step 5), through the selective adsorbing resin column of Soyasaponin is adsorbed, make Soyasaponin from solution, be adsorbed onto on the resin column, with 70-80 ℃ hot water the Soyasaponin adsorption column is inhaled again and taken off, obtain Soyasaponin solution, after super-dry, obtain the finished product Soyasaponin then;
7) process in the step 6) is deviate from Soyasaponin through the whey solution of adsorption column, add in the hydrochloric acid and after, transfer to PH for neutral, then by anionite-exchange resin and Zeo-karb, obtain soybean oligosaccharide solution, after soybean oligosaccharide solution concentration drying, obtain soybean oligosaccharide.
The present invention's beneficial effect compared with prior art is:
1) this technology utilization embrane method is produced soybean protein isolate and protein peptide, replace traditional alkali pickling to sink method, the soybean protein isolate protein quality height that obtains, the nitrogen soluble index height, oil absorbency, emulsifying property, the gelation of product all are better than the heavy method products obtained therefrom of alkali pickling simultaneously.
2) this technology has sepn process and does not have characteristics such as phase transformation, energy consumption are low, easy to operate, safe and reliable, good separating effect, environmentally safe.
3) behind sterilization process, homogenize, emulsifying property, water-absorbent, the oil absorbency of soybean protein isolate and protein peptide is improved.
4) adjust different types of proteolytic enzyme and ultra-filtration membrane, can produce different types of soybean protein peptide with difference in functionality characteristic.
5) this technology in a production line production, has been simplified production technique with soybean isoflavones, Soyasaponin, soybean oligosaccharide, has reduced cost, has increased working efficiency, has effectively utilized raw material.
