Abstract
The invention discloses a functional soybean protein isolate preparation technology. The technology comprises the following steps: carrying out alkali extraction of low temperature soybean meal as a raw material, and carrying out extraction and separation twice to obtain a protein liquid; adjusting the pH value of the protein liquid to below 4.5 for acid precipitation, and centrifuging to obtain a solid protein; sequentially carrying out modification, high pressure homogenization, sterilization and flash evaporation treatment of the solid protein; and adding a soup for the enzymatic hydrolysis denaturation, carrying out high pressure homogenization, sterilization, flash evaporation and spray drying treatment, spraying the soup in a granulating system for the functional conversion, carrying out grading sieving by using a vibration sieve, and carrying out metering packaging. The soybean protein isolate prepared by adopting the technology has the advantages of good water solubility, low viscosity, no peculiar smell and the like, can satisfy the demands of the dairy product processing industry on the functional soybean proteins in the market, and improves the whole production level of the soybean proteins in China.
Description
Technical field
The present invention relates to food processing and soybean further process field, relate in particular to a kind of functional type soy protein isolate preparation technology.
Background technology
Soybean protein isolate is to take a kind of full price protide food additives that low-temperature defatted Soybean Meal is that raw material is produced, and its protein content is up to more than 90%, except being of high nutritive value, also has the functional characteristic relevant to the hobby of food, processability etc.For a long time, many dairy enterprises are all being attempted interpolation soybean protein isolate, improving nutritive value, when supplementing protein content, also can reduce costs.But in dairy products processing criterion, the protein isolate viscosity that requirement is added is low, be as good as and hide, solubility is high, insoluble solid content is lower than certain index etc., and these specification requirements to soybean protein isolate, adopt common, traditional processing mode to be difficult to meet, therefore the enterprise of domestic production dairy-type isolated soy protein is considerably less, be difficult to meet the market demand of dairy products processing.
Summary of the invention
The object of the present invention is to provide a kind of functional type soy protein isolate preparation technology, the advantage such as this technique production yield is high, and it is good that the soybean protein isolate of preparation has dissolubility, and viscosity is low, free from extraneous odour, can meet the specification requirement of dairy products processing.
For realizing above-mentioned technical purpose, the present invention by the following technical solutions: a kind of functional type soy protein isolate preparation technology, comprises the steps:
1) adopting low temperature soy meal is raw material, adds in extractor and mixes with demineralized water, in extractor, adds alkali lye, adjusts pH value of solution to 7, and stirring reaction 30 minutes, by twice extraction and the separated protein liquid that obtains;
2) make protein liquid heavy in time acid of pH value to 4.5, solid protein is obtained in centrifugation;
3) solid protein is carried out to modified, high-pressure homogeneous, sterilization successively and flash distillation is processed;
4) material after flash distillation adds liquid to make the sex change of material enzymolysis by spray pump,
5) material after sex change is again through high-pressure homogeneous, sterilization, flash distillation, spray drying treatment,
6) dried soybean protein isolate enters granulating system, by spraying liquid, product functionality is transformed, and after vibratory sieve classification screening, carries out metering packing.
Spraying described in step 5 is dry, and the hot blast way of contact is parallel type, and EAT is 185 ℃, and temperature of outgoing air is 80 ℃, and atomizing type is pressure type, and product moisture is reached below 7%.
The present invention has following beneficial effect: it is according to existing soybean protein isolate production technology, by adopting different processing parameters, and use protease to carry out modification to albumen, the triple modifications of two enzymes and citric acid, twice sterilization flash system, spiral response Tower System, the modified technology of modified tank emulsification and liquid spray change physicochemical property technology, produce multi-functional, many kinds, high-quality hydrolytic soya bean protein series of products, there is good water solubility, viscosity is low, the advantages such as free from extraneous odour, can meet market by the demand of its dairy products processing industry to functional soy albumen, improve the integral level that domestic soybean protein is produced.
The specific embodiment
Employing low temperature soy meal is raw material, add in extractor and mix with demineralized water, in extractor, add alkali lye, adjust pH value of solution to 7, stirring reaction 30 minutes, extraction mixture is carried out to centrifugation, the protein liquid of separating is stored in temporary tank, solid content is transported in the second extractor, add soft water dilution simultaneously, fully mix, extract 20 minutes, extraction mixture carries out centrifugation, the separated protein liquid going out is stored in temporary tank, the protein liquid of twice separation is transported to the heavy tank of acid, add acid to adjust pH value to 4.5, protein precipitation is separated out, by centrifugation, obtain solid protein, to solid protein, carry out successively modified, high-pressure homogeneous, sterilization and flash distillation are processed, material after flash distillation adds liquid to make the sex change of material enzymolysis by spray pump, material after sex change is again through high-pressure homogeneous, sterilization, flash distillation, spraying is dry, dried soybean protein isolate enters granulating system, by spraying liquid, product functionality is transformed, after vibratory sieve classification screening, carry out metering packing.
The soybean protein isolate good water solubility that adopts above-mentioned technique to prepare, after dissolving, liquid level is floating without protein, after dispersion, without coagula, does not precipitate; Viscosity is low, and protein isolate is carried out to limited enzymolysis processing, can reduce its molecular weight, thereby reduces its viscosity, without peculiar smell such as bitter tastes.
Specific targets are as follows:
