Description

A kind of method that utilization soybean aqueous enzymatic method hydrolyzate makes high-protein bean curd
Technical field
The invention belongs to bean product manufacture field, relate generally to one kind and make high-protein bean using soybean aqueous enzymatic method hydrolyzate Rotten method.
Background technology
Bean curd is the vegetable protein food of high-quality, is that after heating soybean milk, it is white or faint yellow that addition coagulator is made Product.Because it has high protein, minerals and vitamins, the characteristic of low saturated fatty acid, cholesterol and heat so that beans Corruption is increasingly liked by people.Human body, which daily intakes a certain amount of bean curd, hypotensive, reduces cholesterol, improves immunity Effect.But, because bean curd is all the also no substantial amounts of industrialization of small hand workshop production, this causes the matter of tofu product The problems such as amount also has very big defect, such as quality inequality, retentiveness difference, at the same time these phenomenons and theory are not solved also Release clear, this generates serious influence for the development of bean curd, therefore it is that we need badly to develop a kind of bean curd of high-quality The problem of solution.
It is that a kind of emerging " safety and environmental friendliness " carries oil tech that aqueous enzymatic method, which carries oil, and is entered due to digesting in aqueous phase OK, the functional materials in soybean, such as isoflavones, soyasaponin, Soybean Peptide, soyabean oligosaccharides, soybean dietary fiber Isoreactivity material is retained in aqueous phase.Most of current aqueous enzymatic method Soy hydrolysate is confined to constituent and functional character Research, but application in the product is seldom, mainly uses spray drying technology to hydrolyzate dust obtaining soybean The products such as polypeptide, the form of product is relatively simple, inadequate for the availability of hydrolyzate, causes substantial amounts of nutriment to be lost in. If hydrolyzate is applied in bean curd, it can not only enable hydrolyzate sufficiently using not being wasted, and because hydrolyzate In make it that the quality of bean curd is further lifted containing substantial amounts of nutriment.
During bean curd is made, required raw material water is replaced with hydrolyzate, it is substantial amounts of because containing in hydrolyzate Soluble protein, soluble protein can increase the curdled milk of bean curd, and the protein content in bean curd is also further carried It is high so that the bean curd produced not only has higher nutritive value, and with delicate mouthfeel, homogeneous and good holds Aqueous the features such as.Simultaneously can be with using water wisely.
High pressure micro jetting technology is under the pressure effect of super-pressure (310MPa), by aperture very small valve core, production The fluid of raw several times of velocities of sound, with particle size distribution it is uniform, simple to operate, pollution-free, can online cleaning-sterilizing, can high efficiency Many advantages, such as carrying out breaking-wall cell.This technology is applied in the manufacturing process of bean curd, can have soya-bean milk scattered, Matter, the effect of emulsification, the molecular structure of soya-bean milk is changed, and the structure of soya-bean milk can be made more homogeneous, improves the breast of soya-bean milk The property changed so that the curdled milk of bean curd is improved, when selecting slurry so that bean curd is easier solidification, produces homogeneous high egg White peas or beans is rotten.
Based on the existing quality problem of bean curd, replace water to make the bean curd of high protein with hydrolyzate, can solve the problem that existing beans The reason for corruption is because of coagulator and soybean varieties cause the retentiveness of bean curd and the quality problems of poor taste while can also increase beans Rotten protein content.
The content of the invention
The present invention to be solved the problem of hydrolyzate can not make full use of and the existing tofu quality of improvement is unbalanced not Foot reaches the purpose of increase tofu quality there is provided a kind of method that utilization soybean aqueous enzymatic method hydrolyzate makes high-protein bean curd.
The technical problems to be solved by the invention are achieved through the following technical solutions:
A kind of method that utilization aqueous enzymatic method hydrolyzate prepares high-protein bean curd, this method comprises the following steps:(1)The receipts of hydrolyzate Collection:Soybean, which is crushed, carries out extrusion processing after decortication, digested with alkali protease, the material after enzymolysis will carry out the enzyme that goes out Processing, collects hydrolyzate, described enzymolysis and enzyme condition of going out is afterwards:The solid-liquid ratio of expanded product and water is 1:4-8, enzyme concentration For the 1-3% of expanded mass fraction of product, hydrolysis temperature is 50-70 DEG C, and enzymolysis pH is 7.0-9.0, and enzymolysis time is 1-2h, Enzyme-removal temperature is 80-90 DEG C, and the enzyme time of going out is 5-10min;(2)Select beans:Selection full grains, free from insect pests, without what is crushed, surface Wrinkle-free glossiness soybean, and soybean rinsed well with clear water standby;(3)Soak beans:At room temperature for select soybean with Water is according to 1:4 ratio is soaked at 20 DEG C, and soak time is 18h;(4)Defibrination:By the soybean soaked and hydrolyzate according to 1:4 ratio carries out defibrination, and wherein defibrination is carried out in three times, and the 30% of total hydrolyzate is added for the first time and carries out defibrination, is added for the second time Enter total hydrolyzate 30% carries out defibrination, and 40% that total hydrolyzate is added for the third time carries out defibrination, is added during defibrination 0.5% sodium bicarbonate solution;(5)Filter pulp:Bean dregs are removed by the way of extruding with 2 layers of gauze;(6)Mashing off:It will filter Soya-bean milk carry out mashing off under conditions of 90 DEG C, the mashing off time is 8min, constantly to be stirred during mashing off, mashing off Soya-bean milk is cooled to room temperature after finishing;(7)Soya-bean milk is entered into the processing of horizontal high voltage microjet:Soya-bean milk is with high pressure microfluidizer in 25 DEG C processing, processing pressure is 100MPa, and number of processes is 4 times;(8)Point slurry:Gluconic acid lactone is dissolved in water, side stirring While adding 0.5% gluconic acid lactone into soya-bean milk;(9)Finished product:The soya-bean milk for selecting fat is added in the mould of shaping be incubated it is quiet Finished product is obtained after putting 15min, stabilization to be formed.
Described preferred parameter is:The solid-liquid ratio of expanded product and water is 1:6, enzyme concentration is expanded mass fraction of product 2%, hydrolysis temperature is 55 DEG C, and enzymolysis pH is 9.0, and enzymolysis time is 2h, and enzyme-removal temperature is 90 DEG C, and the enzyme time of going out is 10min; The most ratio of greater inequality of soybean and hydrolyzate is 1 in this method:4;The preferred parameter for adding sodium acid carbonate is 0.5%;Add in gluconic acid The preferred parameter of fat is 0.5%.
This method is on the basis of traditional bean curd is made, the water in raw material to be replaced with hydrolyzate, one kind is produced High-protein bean curd.This method has the protein content for improving bean curd, increases the gelation of bean curd so that the delicate mouthfeel of bean curd, Homogeneous lubrication.
