Description

A kind of soya-bean polypeptides nutrient solution and its preparation method and application
Technical field
The present invention relates to a kind of health food, be specifically related to a kind of soya-bean polypeptides nutrient solution, and its preparation method and application.
Background technology
Protein is the substance basis of life, is the human body indispensable nutriment that grows, and protein is made of several amino acids, wherein is called oligopeptides by 3~10 amino acid with the compound that peptide bond links to each other; Be called polypeptide by 10~50 amino acid with the compound that peptide bond links to each other; 50 are called protein with upper amino acid with the compound that peptide bond links to each other.
After always people think that protein is taken in, must it be hydrolyzed into amino acid whose form through the various enzymes of alimentary canal and just can be absorbed.In recent years, a large amount of result of study of scientist shows: protein not is that complete hydrolysis becomes amino acid after taking in, but major part just is absorbed when the form of peptide.Find that simultaneously the absorbed speed of polypeptide is faster than free amino acid, absorptivity is higher, particularly little molecule oligopeptides.
Protein is as nutriment, mainly form and the part free amino acid with peptide could absorb in human body, bring into play various physiological functions, thus, polypeptide is very close with healthy relation, he reconciles and is arranging life from being born to the overall process of death, replenishes nutrient protein take the form of polypeptide as best to human body.Different crowds is replenished the allogenic polypeptide goods in right amount, immunologic function is prevented and cured diseases, strengthened to human body, it is very important improving body health quality.
The protein of necessary for human mainly is to absorb in driven, the vegetable protein food.Recent studies shows that animal protein contains a large amount of fat, cholesterol, the much more edible generation that can cause many " rich man's diseases " such as hypertension, high fat of blood, coronary heart disease.Vegetable protein substitutes animal protein and is paid attention to by people.
Vegetable protein is take cereal as main, and soy protein content is up to more than 40% in the cereal, and the amino acid kind that forms soybean protein is more complete.Wherein, contain the amino acid that 9 kinds of human bodies can not synthesize voluntarily, be called " necessary amino acid ", amino acid balance is good.Soya-bean polypeptides, united state food and agricultural organization is recommended as " the ideal source of phytoprotein ".
Research to soy bean protein hydrolysate starts from the sixties in 19th century, is at that time to use acid, alkali under fixed temperature catalytic pyrolysis.But many defectives such as this chemical method causes the nutritional labeling loss excessive, and side reaction is many, and organoleptic properties is poor.To the eighties in 19th century, because the speed of enzymology technology hails exhibition, the U.S., Japan have obtained larger progress with enzymatic process, to the eighties in 20th century, Japanology more comprehensive, carrying is not physicochemical characteristic, different physiological roles and application system comparatively all to soya-bean polypeptides, and developed several functions food, resistance should living infant food, the nutritious supplementary pharmaceutical such as sports food.
At present, it all is enzyme hydrolysis process that countries in the world produce soya-bean polypeptides, this method, complex technical process, and the bitter taste of hydrolysate still can not solve at all.Exist many drawbacks such as degree of hydrolysis is low, weak flavor (bitter taste), complex technical process, production cost height, limited the demand in application and market, anxious to be resolved is: seek new method, new technology.
China is the native place of soybean, before more than 2000 years, and founder of the Han Dynasty's grandson. Huainan king Liu An, in " Mt. Bagong " in Jiangsu makes pills of immortality process, invented with soybean and made " bean curd ", spread all over all over the world so far, China only is in the preliminary working stage of bean product.Until the later stage eighties in 20th century is just carried out primary study to soya-bean polypeptides, and list exploitation and the application of " soya-bean polypeptides " in the enforcement period of the ninth five-year plan national key scientific and technological project.China National Academy of Food ﹠ Fermentation Industries is the earliest to the research institution of soya-bean polypeptides, and has born " 95 " brainstorm project.Now finish soybean or dregs of beans and extracted the task of separating soya-bean polypeptides.Used enzymolysis process and soya-bean polypeptides product have all reached world level, maintain the leading position at home, but not yet scale of input production, product is not still gone public.
According to the latest survey result, the method for producing soya-bean polypeptides both at home and abroad all is enzyme hydrolysis process, all has following problem:
(1) being used for the enzyme kind of hydrolysis, more single (only have trypsase, alkali protease, neutral proteinase, papain several, degree of hydrolysis is low, hydrolysate weak flavor (bitter taste is arranged).
(2) enzymolysis mechanism, degree of hydrolysis and zymolyte characteristic relation are indefinite, cause hydrolysis process control to lack theoretical direction, and control is difficult.
(3) bitter taste of hydrolysis still can not solve at all, and application is restricted.
(4) the enzymolysis process process is complicated: soybean, and---------hydrolysate separation---debitterize flavor---desalination etc. cause production cost high to protein isolate in enzyme hydrolysis.
Above problem: degree of hydrolysis is low, weak flavor, poor quality control, production cost are high, make the soya-bean polypeptides product be difficult to appear on the market.
Summary of the invention
The object of the invention is to: a kind of soya-bean polypeptides nutrient solution is provided, various diseases is had significant prevention effect.
Above-mentioned purpose of the present invention is achieved through the following technical solutions:
