Description
Technical field
The present invention relates to food processing field, in particular to a kind of five-cereal health-care peptide and preparation method thereof.
Background technique
Some metallic elements especially microelement, such as iron, zinc, copper, selenium, although extremely low in people's in-vivo content,
Extreme influence the existence and health of people.Their insufficiency of intakes excessively can all cause Human Physiology disorder or disease to some extent
Disease.The research of polypeptide-chelate of metal ion starts from the last century 60's.The beginning of the eighties, U.S.'s Albion laboratory iron support
Elements compounding animal/vegetable protein generates albumen iron complexes.Thus start, the research of polypeptide-chelate of metal ion causes
The concern of whole world scholar.Currently, in the world there is the disease of the metallic elements such as calcium, iron, zinc shortage in the people in many areas
Shape, therefore, development of metallic component extender have great and real meaning.
Iron is minerals needed by human, and the iron in diet is mainly with Fe3+In the presence of body can not be utilized directly, Yi Yinqi
Asiderosis.Global about 3,000,000,000 people suffer from anaemia, and male's disease incidence is 10%, and women 20%, and pregnant woman 40%, and children are up to
50%.The defects of iron supplementary used at present is low in the presence of being absorbed and utilized, and stability is poor, stimulating gastrointestinal road.Therefore utilization rate is sought
Height, the ferrous-fortifier of Small side effects are the targets of numerous researchers.Amino-acid chelate is as third generation iron supplementary, utilization rate
It is universal higher.Ion channel need not be walked after metal ion and peptide or chelating amino acids, peptide can be entered or the channel of amino acid is inhaled
It receives, largely promotes the absorption of iron.Small peptide can completely be absorbed by organisms and enter blood in the form of two, tripeptides and follow
Ring.Peptide and free amino acid have relatively independent mechanism of absorption in human body, and compared with the transport system of amino acid, peptide exists
Absorption in human body, which has, to be absorbed fastly, and high-efficient, low energy consumption, and carrier is not easy the advantage being saturated, so peptide chelate complex is easier quilt
Body absorbs.

Fireballing feature.
Alkali protease Alcalase FG 2.4L derives from bacillus licheniformis, Glu in cleavable albumen,
The carboxylic end peptide bond of Met, Leu, Tyr, Lys and Gln, and relatively large amino acid side chain, alkali protease act more easily on peptide
Key.
Using multienzyme fractional hydrolysis, content of peptides in hydrolysate can be increased and reduce amino acid content, because identical
Peptide is generated under albumen enzyme effect, restriction enzyme site is similar or identical, between the equal 500Da--1000Da of molecular weight, generates after enzymatic hydrolysis
Small peptide, chelated iron have polypeptide outside the nutritive value of itself, and there are also the effects that benefit iron is enriched blood.
Plant separation protein contains a large amount of phytic acid, therefore sloughs before preparing metallo-chelate the phytic acid in albumen and not only may be used
To improve human body to the absorbability of mineral element, while the ability of protein peptides chelated metal ions can also be improved, eliminate and plant
Albumen and metal ion binding capacity can be improved in the influence of acid and metal ion-chelant, the phosphorylation modification of protein peptides, then
It is allowed in conjunction with frerrous chloride, prepares iron chelating peptide, and the step of finally establishing optimization and reaction condition, reach maximum
The effect of phosphorylation and strongest iron binding capacity.
By carrying out phosphorylation modification to soybean protein isolate using sodium tripolyphosphate, hence it is evident that increase the dissolution speed of albumen
Degree, but solubility and viscosity have no significant change.
The present invention has following technical effect that compared with prior art
A kind of five cereals peptide and preparation method thereof, five-cereal health-care peptide is chelated after multienzyme stepwise discretization iron by various plants albumen
, the various plants albumen includes: soybean protein, wheat germ protein, zein, peanut protein, walnut protein, passes through multienzyme
Hydrolyze method, polypeptide molecular weight between 500-1000Da, polypeptide chelate iron make chalybeate be converted into easily absorption, easily store it is organic
Iron, alcohol precipitation realize the separation of Organic Iron and inorganic iron, make the more preferable chelated iron of polypeptide, and polypeptide can play idiotrophic value, simultaneously
There is the effect of blood-nourishing and iron-replenishing.

For mulser after 20000-22000r/min handles 5min, solid-liquid ratio g/mL is 1:100, alkali protease is added, when enzymatic hydrolysis
Between be 3-4h, obtain enzymolysis liquid, keep the pH value of reaction system constant in reaction process;
S4: by the enzymolysis liquid, boiling water bath 10min enzyme deactivation is cooled to 30 DEG C and adjusts pH value to 4.0 hereinafter, HCl solution is added,
Filtering, obtains supernatant;
S5: by the supernatant, solid-liquid ratio g/ml is that sodium trimetaphosphate is added in 2:100, and NaOH solution is added to adjust pH value to 8.0,
30-40 DEG C of reaction temperature, time 75-90 min obtains reaction solution one;
S6: by the reaction solution one, being added vitamin C, vitamin B and chalybeate, 30-40 min reacted in constant temperature heating water-bath,
And whole nitrogen charging gas shielded, so that the solution in reaction flask is in anaerobic gaseity, obtains reaction solution two;
S7: by the reaction solution two, the dehydrated alcohol with two equal volume of reaction solution is added, filtering precipitates drying, obtains xeraphium
End;
S8: xylitol is added in the dried powder, is uniformly mixed, obtains five-cereal health-care peptide.
