Abstract
The invention discloses a method for preparing protein hydrolyzate from abalone viscera through complex enzyme hydrolysis, bitterness shielding and other technologies. Complex enzymes comprise alkali protease and papain. The protein hydrolyzate is prepared from abalone viscera by cleaning, pulping, hydrolyzing with the enzymes, inactivating the enzymes and shielding bitterness by using ethyl maltol in sequence. The method effectively utilizes a side product, namely viscera, generated during abalone processing, and the bitterness of the protein hydrolyzate is avoided; the prepared protein hydrolyzate has high content of free amino acid, high absorptivity of human body, rich nutrition and delicious flavor, and can be used as an additive to be widely applied to products such as cans, sauces,fodders, plant nutrient solutions and the like.
Description
Technical field
The present invention is specifically related to a kind of method of preparing protein hydrolyzate from abalone viscera through complex enzyme hydrolysis.
Background technology
The abalone delicious flavour, nutritious, per 100 gram Fresh abalone fishes contain protein 12.6 grams, fat 0.8 gram, carbohydrate 6.6 grams, and contain the mineral matter and the multivitamins such as calcium, phosphorus, iron, zinc of needed by human body." dietetic materia medica " record, abalone goes into the logical stasis of blood of liver, goes into intestines and washs dirt, does not hinder vigour, establishing-Yang, living hundred arteries and veins.Abalone has higher nutritive value and medical value, is that amino acid content is the most comprehensive in the ocean, one of fatty, that cholesterol level is minimum biology.
The abalone internal organ usually are used as leftover bits and pieces and discard, and wherein discarded leftover bits and pieces accounts for more than 19% of full abalone quality in the tin product process.Contain a large amount of protein in the abalone internal organ, contain trace element and vitamin etc. in addition.Its protein can be hydrolyzed into and be the peptide and the amino acid that can directly absorbed and utilize by animal, and discharges the food calling material of numerous fish and shrimp.Therefore, the abalone internal organ are good protein resources.
At present the utilization to leftover bits and pieces such as abalone internal organ mainly is to produce the feed fish meal, and valuable ingredients is wherein still underused.Separation and purification, polysaccharide that the research of abalone internal organ mainly contains alkaline phosphatase extract and anti-oxidant research, acid hydrolysis and mailland reaction product analysis thereof etc.; Acid hydrolysis is mainly adopted in hydrolysis for internal organ; But the amino acid whose yield of acid hydrolysis is lower, and the local flavor of hydrolyzate is not good enough.
Publication number be CN 101433345A disclosure of the Invention a kind of method of comprehensive utilization of grass carp harslet; The main process of this method is: grass carp harslet is after cleaning out; Take off the raw meat deodorization with acetic acid, sodium chloride and sodium sulfite mixed liquor and handle, smash trypsin digestion to pieces; Centrifugal, isolate the upper strata crude fish oil.Crude fish oil can make refined fish oil through refining.Lower floor's enzymolysis liquid behind vacuum filtration, with active carbon once more debitterize take off raw meat, spray-drying makes fish protein polypeptide powder and amino acid powder then.Polypeptide powder mainly contains dipeptides and tripeptides, and is rich in multiple mineral element, be prone to digested and assimilated by enteron aisle, and be a kind of high-quality nutriment.Amino acid powder contains the amino acid A wide selection of colours and designs, can be the additive of various amino acid nutrient enhanced products.Process conditions of the present invention are gentle, cause the protein loss bigger but take off raw meat with the active carbon debitterize.
Publication number be CN 1334258A disclosure of the Invention a kind of production method of plant nutrient agent, it is characterized in that with marine organisms and pluck be raw material, after crushed, add hydrolysising protease and carry out enzyme digestion reaction, obtain finished product through filtering, concentrating again.Adopt single hydrolysising protease, the proteolysis yield is low.
Summary of the invention
