Description

One seed oyster polypeptide child nutrition supplement and preparation method thereof
Technical field
The present invention relates to a kind of food compositions or its processing, especially seed oyster polypeptide child nutrition supplement and preparation method thereof that contains the peptide class.
Background technology
Children are special colonies, and its particularity just shows that they are in body, brain growth phase.Therefore; Sufficient, the rational nutrition of allotment is the material base of upgrowth and development of children; If subalimentation then at first cause children's body weight not increase even descend finally also can influence the growth of height and the function of other each system of health, like immunologic function, endocrine function, dysfunction of nervous regulation etc.Because children are in the puberty, its intestines, stomach function are sound as yet, and the child nutrition food of being sold on the market of being arranged in pairs or groups by cereal or fruits and vegetables class and fish, meat is for children, and ubiquity non-digestible deficiency.
In order to improve children's digestive system, optimize the gut flora balance, enhance immunity power, the absorption of help nutriment, numerous technical staff have invented the children's health food that has prebiotics or probio.For example: on November 17th, the 2004 disclosed CN1545937A Chinese invention patent ublic specification of application disclosed " a kind of children's health food that contains prebiotics and preparation method thereof ", this health food comprises following composition: prebiotics 5~80%, amino acid 5~30%, trace element 0.1~3%, food additives 2~89.9%.It has to improve and grows, to promote the function that digests.For another example; In on August 15th, the 2007 disclosed CN101015570A Chinese invention patent ublic specification of application disclosed " children's health food of probiotics and production technology thereof ", it comprises following composition: bifidobacterium infantis, lactobacillus acidophilus, saccharomyces cerevisiae, yeast zinc, vitamin C, vitamin B1, vitamin B2, vitamin B6, cobalamin, niacinamide, calcium pantothenate, oligomeric FOS, glucose, 2% Gonak.It stimulates immune cell with bacterium system bacterium, builds up resistance, and reduces enteron aisle pH value, helps the absorption of calcium, phosphorus, zinc, ferro element, thereby improves symptoms such as diarrhoea, vomiting, abdominal distension, dysentery, constipation, apocleisis, indigestion, anaemia, calcium deficiency rapidly.Above-mentioned disclosed children's health food only has the regulating system immunologic function, improves the gut flora balance, promotes useful physiological functions such as absorption of nutrient ingredients, but the required nutriment of upgrowth and development of children is not played supplementary function.
We know, fertile smooth, the delicious flavour, nutritious of oyster meat have the laudatory title of " seabed milk ".Modern nutriology research shows: oyster meat is rich in good protein, glycogen and vitamin A, B 1, B 2, the multiple trace element that human physiological functions is had important function such as D, zinc, calcium, phosphorus, copper, iodine, manganese, barium.Particularly: the good protein in the oyster meat comprises the amino acid of needed by human, and amino acid is formed perfect, surpasses cow's milk and human milk; Also contain abundant natural taurine in the oyster meat; The physiological function of taurine relates to retina, central nervous system, cardiovascular system, liver and gall, internal system etc.; And multiple metabolic process in the participation human body, have effects such as children's brain development of promotion and mind-tranquilizing brain-strengthening; The content of zinc occupies first of the human foods in the oyster meat, and zinc is participated in nucleic acid, enzyme etc. and synthesized, has the effect that promotes body development, enhances human body resistance, and children lack zinc can cause growth retardation; Fat content in the oyster meat is less, but aliphatic acid form in content of polyunsaturated fatty acid abundant, mainly be EPA and DHA, it can effectively promote brain cell and neural growth, enhance memory power and thinking ability, raising IQ, the eyesight of improving.Therefore, oyster meat can be used as the first-selected wholefood of upgrowth and development of children.
At present, also do not see the report of oyster polypeptide powder that the oyster meat processed obtains and prebiotics, the synthetic child nutrition supplement of probiotic group.
Summary of the invention
In order to overcome the prior art children's health food only produces useful physiological action to the host deficiency, the present invention provides a kind of reasonable, multiple functional, that production technology is advanced oyster polypeptide child nutrition supplement and preparation method thereof of forming.
The technical solution adopted for the present invention to solve the technical problems is: a seed oyster polypeptide child nutrition supplement; It comprises probiotics preparation and prebiotics; It is characterized in that: it also includes the oyster peptide powder, and the percentage by weight of its each component is respectively: oyster peptide powder 40-60%, probiotics preparation 20-30%, prebiotics 10-40%.
Described oyster peptide powder is oyster albumen control enzymolysis, and the enzymolysis product that obtains mixed polypeptide is through the resulting peptide powder of drying.
Described probiotics preparation is following one or more the microencapsulated formulation of probio: bifidobacterium infantis, bifidobacterium bifidum, lactobacillus acidophilus, bifidobacterium adolescentis, streptococcus thermophilus, lactobacillus bulgaricus, bifidobacterium longum, bifidobacterium breve.
Described prebiotics is that FOS and oligoisomaltose combine in 1: 1~1: 3 ratio of mass ratio.
The preparation method of one seed oyster polypeptide child nutrition supplement is characterized in that: process the following step:
1., the preparation of oyster peptide powder
It is raw material that fresh oyster meat is chosen in the processing of a, raw material, sends into tissue after cleaning and smashs homogenate in the equipment to pieces;
