Description
Technical field
The present invention relates to the Application way of a kind of bean curd yellow pulp water, relate generally to a kind of method preparing soy oligosaccharides glycopeptide functional drinks from bean curd yellow pulp water.
Background technology
Semen sojae atricolor is the food of a kind of high nutritive value, containing nutritional labelings such as substantial amounts of unsaturated fatty acid, high quality protein, oligosaccharide, saponin, multivitamin, dietary fiber, phospholipid, various trace elements.Semen sojae atricolor is processed produces a variety of bean product, is the useful food of the cardiovascular patients such as hypertension, arteriosclerosis, heart disease.
Bean curd is the green health food that China is traditional, the history of existing more than 2,100 year.Bean curd iron content, magnesium, potassium, nicotinic acid, copper, calcium, zinc, phosphorus, folic acid, vitamin B1, lecithin and vitamin B6.Bean curd, by the human body absorption to soybean protein and utilization, becomes to be more prone to, bean curd great variety of goods, of all shapes and colors, there is unique flavor, it is possible to be produced out the dish of a great variety, to adapt to taste and the hobby of different regions people, liking by our people, periphery various countries and the people of the world deeply.Bean curd high protein, low fat, have blood pressure lowering, blood fat reducing, effect of cholesterol reducing.That old children is all suitable, health preserving health preserving, life prolonging delicacy excellent product.
Bean curd preparation processes need to add the Semen sojae atricolor weight about water of more than 10 times, substantial amounts of yellow seriflux can be produced when bean curd drains, in yellow seriflux, solid content is about about 2%, wherein total sugar content is about about 0.63% (oligosaccharide content >=35% such as stachyose, Raffinose), protein content is about about 0.4%, content of ashes is about about 0.28%, and COD is about 19000mg/L.The Semen sojae atricolor of different regions, component content slightly difference in its yellow seriflux.When yellow seriflux directly discharges, because its COD value concentration is high, become serious polluter.Owing to the lactalbumin in yellow seriflux is mainly trypsin inhibitor, when taking this waste water of biological way end treatment, this inhibitor also suppresses growth of microorganism, causes biochemical process to process this waste water relatively difficult.
Summary of the invention
In order to make full use of the beneficiating ingredient in bean curd yellow pulp water, solve yellow seriflux simultaneously and administer predicament, the present invention follows cleaning and produces, the guiding theory recycled, the Application way of a kind of bean curd yellow pulp water is provided, relates generally to a kind of method adopting biological enzymolysis, membrane separation technique that the sugar in bean curd yellow pulp water and Protein Extraction preparation are become soy oligosaccharides glycopeptide functional drinks.
The purpose of the present invention can be realized by following step:
A, enzymolysis, add protease in yellow seriflux, and making the protein digestion in water is oligopeptide；
B, first order membrance concentration, adopt ultrafilter membrane concentration to a step gained enzymolysis solution, and cycles of concentration is about 10 ~ 12 times；
C, second level membrance concentration, adopt reverse osmosis membrane concentration to b step gained ultrafilter membrane filtrate, and cycles of concentration is about 8 ~ 10 times, COD content≤100mg/L in reverse osmosis filtrate, and not whey protein, can be back to soybean processing process or directly discharge；
D, calcium are heavy, the concentrated solution that merging b step and step c obtain, and add calcium hydroxide and regulate pH value, because oligopeptide and sugar are water-soluble substances, are present in supernatant；
E, separation, use the feed separation that Step d is obtained by sheet frame separator to obtain clear liquid；
F, modified, the clear liquid that step e is obtained adds food stage adjuvant according to the market demand and adjusts mouthfeel；
G, fill, enter bottle by the filling liquid after adjusting mouthfeel；
H, sterilizing, adopt pasteurization by bottling liquid.
The protease added in described step a can be papain, alkaline protease or neutral protease, and the addition of protease is about 0.5 ‰ ~ the 1 ‰ of yellow seriflux amount, enzymolysis time 1h ~ 2h；
The ultrafilter membrane adopted in described step b, its membrane aperture is 1～5 nanometer, and working condition is: pressure 0.8～1.2MPa, temperature 40～50 DEG C；
The reverse osmosis membrane adopted in described step c, working condition is: pressure 3.0～3.5MPa, and temperature is 40～50 DEG C；
Described step d adds calcium hydroxide and regulates the pH value of yellow seriflux to 6.0～6.5；
Its aperture of filter screen of sheet frame separator used in described step e is 800 ~ 1000 orders.
The present invention comprehensively adopts the soy oligosaccharides glycopeptide functional drinks that the sugar in yellow seriflux and Protein Extraction are prepared by biological enzymolysis, membrane separation technique, in beverage, the oligosaccharide content such as stachyose, Raffinose is about about 1.2%, soybean oligopeptide is about about 2.0%, possibly together with the beneficiating ingredient such as soybean saponin, soybean isoflavone, there is certain health nutrient function, its good market prospects；Simultaneously because reverse osmosis filtrate can be back to soybean processing process, the reuse water yield is up to 80%, preferably resolving yellow seriflux and directly discharge the pollution problem of generation, water-saving and emission-reducing, and environmental benefit is obvious；Produce functional drinks product and also can increase the income from sales of enterprise.
