Beneficial effects of the present invention are as follows:
Walnut oligopeptide prepared by the present invention is by walnut kernel by decortication and ungrease treatment, and then passes through biological enzymolysis skill
Art is prepared.
Since walnut kernel brown endotesta contains phenols and tannin, the mouthfeel and color of walnut product often will affect
Pool, also, this substance can cause protein solubility to decline, to reduce walnut oligopeptide with protein covalent bond
Yield, so needing to remove it.The method for generalling use dipping by lye at present carries out the decortication processing of walnut kernel, this method has
Following drawback: 1) by alkaline process immersion treatment, the content of walnut kernel essential amino acid can decline, and the type of limiting amino acid increases
Add, amino acid score decline;2) spent lye has some impact on environment, and the institute's effluent of walnut kernel lye dipping workshop is Huang
Black troubled liquor, surface are and organic containing lipid, protein and walnut kernel powder etc. with white foam and a large amount of suspended matters
Object, each contamination index of the waste water is higher than national secondary discharge standard after measured, and having to pass through wastewater treatment can discharge, this
Sample considerably increases production cost.And the hot-water soak processing used in the present invention and enzymolysis processing, walnut kernel nutritional ingredient damage
It loses less and pollution-free, is a kind of green, efficient method.
To reduce fat content in product, protein active in walnut kernel is protected, the yield of protein is improved, usually by walnut
Benevolence carries out ungrease treatment.Currently used degreasing method can cause walnut egg frequently with organic solvent method degreasing, hot environment
The denaturation of white matter and the loss of other nutritional ingredients, and organic solvent also results in certain pollution to environment.What the present invention used
Subcritical fluid techniques degreasing, actually to the abstraction technique of grease, due to subcritical fluid extraction grease, extraction cycle consumption
When it is short, and extraction yield is high, and walnut oil colours is shallow, bright, not will cause the denaturation of walnut kernel albumen, and one side can reach in this way
To the purpose of degreasing, on the other hand, the walnut oil extracted is best in quality, can be developed further into Related product.
Therefore, by peeling above, defatting technology, remain the nutriment of walnut kernel to the maximum extent, and improve
The yield of walnut oligopeptide.
The intrinsic fishy smell of oyster, and due to producing small peptide and micro hardship in the enzymatic hydrolysis preparation process of oyster oligopeptide
Flavor nucleotide has certain adverse effect to sense organ.The present invention has carried out flavoring processing to the oyster oligopeptide of enzymatic hydrolysis preparation.Mesh
Before to be usually used in the technology of flavoring and taste masking include: addition corrigent, bitter tasting retarding agent, taste bud paralyzant, coating, amberlite
Rouge technology etc..Inclusion technique is the flavoring technology for continuing to develop and occurring recently as Modern preparations technology.The present invention is for the first time
Flavoring processing is carried out to oyster oligopeptide using inclusion technique, compared to using additive, highly-safe, significant effect, simultaneously
Easy to operate compared to ion-exchange-resin process, production cost is low.The present invention uses high pressure homogenization technique and high pressure microjet skill
Art is included, and is very significantly improved by the high-pressure homogeneous partial size for handling obtained emulsion and dispersibility.With it is traditional
High-pressure homogeneous mode is compared, and high pressure microjet processing pressure is higher, and faster, collision energy is bigger for fluid velocity, and product particle is more
Carefully, up to nanoscale, to improve stability of solution, the oyster oligopeptide embedding rate by flavoring processing is high with this condition,
Delicate mouthfeel.
In the preparation process of biologically active peptide, in order to obtain the peptide fragment of high activity, enzymolysis process is vital.Enzymatic hydrolysis
Technique is broadly divided into single enzyme and multi-enzymatic hydrolysis method, and multi-enzymatic hydrolysis method is divided into mixed enzyme and substep enzyme hydrolysis method.Production at present
Using it is most be single enzymolysis method, this method simple process, but generally oligomeric compared with high yield pulp1 and relatively small molecular weight in order to obtain
Peptide, then it is more to consume enzyme amount, takes a long time, product has stronger bitter taste and more salinity.And the complex enzyme applied in the present invention point
Step enzymatic isolation method prepares oligopeptide, and less enzyme amount and short period can get the lesser oligopeptide of molecular weight, and better assure that
The functional activity of polypeptide.In the present invention, complex enzyme zymohydrolysis condition can be controlled by substep to control degree of hydrolysis, to obtain
The polypeptide of required molecular weight ranges.Oyster oligopeptide and walnut oligopeptide prepared by the present invention are being visited using degree of hydrolysis as index
It has begged in the theory of enzymolysis kinetics, has optimized enzyme digestion reaction parameter, the digestion action site based on different enzymes passes through hydrolysis
Degree, oligomeric peptide yield and amino acid form to screen the type of enzyme and optimization enzymolysis process, are less than so that molecular weight be prepared
1000 oligopeptide, the advantages of reaching absorptivity high, good biocompatibility.
