Abstract

The invention discloses a manufacture method of hemachrome and discolored globin powder. The method comprises the steps that: after zymohydrolysis and equal point deposition of the raw material hemoglobin are carried out, the globin powder is prepared by supernatant by concentration and drying; and the hemachrome is prepared by precipitation and crystallization. The method of the invention can fully utilize the precious protein resources of poultry blood, jointly extract the hemachrome and eatable discolored globin powder and has not waste; the obtained discolored globin powder has good color, few impurities and high content of proteins. The method has the advantages of simple operation, low lost and clean without contamination, and being suitable for industrial production.

Description

The production method of protoheme and decolouring globulin powder
Technical field
The present invention relates to the production method of protoheme and decolouring globulin powder, belong to food chemistry and biochemical field.
Background technology
Blood accounts for the 7%-8% of domestic birds and animals total protein concentration, and itself is nutritious, and protein content is up to about 20%, have " liquid meat " and title.Albumen has albumin, oxyphorase etc. in the blood, and wherein oxyphorase accounts for 70%-80%.But because the disgusting fishy smell of oxyphorase, except being used for blood bean curd on a small quantity, major part is dropped, and has not only wasted the protein resource of a large amount of preciousnesses but also has polluted ecotope.Oxyphorase is a homotetramer of being made up of four subunits, and each subunit contains a globin and one bonded protoheme with it.Wherein a kind of especially good hematinic of protoheme and important medicine chemical material.Therefore making full use of blood resource can protect environment again and can create good economic benefit by efficent use of resources, is subjected to domestic and international extensive concern.
Heme moiety and the globin part of fully rationally utilizing the artis of blood resource to be to separate oxyphorase have proposed a variety of separation methods now.Traditional method is utilized the organic solvent extracting, comprises the Glacial acetic acid extracting, the extracting of small molecules ketone such as acetone, methylethylketone etc., small molecular alcohol extracting such as methyl alcohol, ethanol etc.The organic solvent extracting is the extracting protoheme well, but needs very a large amount of organic solvents, and the protoheme that extracts 1kg needs the organic solvent of 800L-1000L, so inefficiency, brings huge inconvenience to operation, and also bigger to environmental hazard.U.S. Pat 4376727 proposes to adsorb protoheme with carboxymethyl cellulose, this method can solve protoheme and separate with globin, but what obtain is the mixture of protoheme and carboxymethyl cellulose, can not obtain pure protoheme, and carboxymethyl cellulose can not be regenerated, therefore this method cost is higher, has limited its use.Chinese patent ZL87101834 and ZL200610080022.9 use tensio-active agent as catalyzer crystallization protoheme, crystallization effect is better, but this method blood cell is easy to generate globin and protoheme co-precipitation in heat-processed, and address this problem just needs accurately control reaction process and utilization complicated operations equipment; The more important thing is that the protein powder that this method generates contains tensio-active agent, its person poultry safety's property is under suspicion.
Summary of the invention
The purpose of this invention is to provide a kind of simple to operate, with low cost, free of contamination protoheme and the decolouring globulin powder production method.
The production method of protoheme of the present invention and decolouring globulin powder, its step is as follows
1) the oxyphorase raw material is dissolved in water and stirs, the preparation mass concentration is at the 1%-20% haemoglobin aqueous solution, add proteolytic ferment then, the addition of proteolytic ferment is the 0.05%-10% of protein content in the hemoglobin solutions, regulate pH1.5~9.0, carry out enzymolysis under 25~70 ℃ of temperature, obtain enzymolysis solution, the enzymolysis extent control is at degree of hydrolysis 5%~40%;
2) the pH value of regulating enzymolysis solution is filtered to 2.0-6.0, collects the protoheme precipitation, gets the protoheme work in-process after the drying, and filtrate is not for containing the protein solution of protoheme;
3) add entry, concentrated hydrochloric acid and nonionogenic tenside in the protoheme work in-process, and stir, with dry weight basis, control protoheme work in-process: water: concentrated hydrochloric acid: the mass ratio of nonionogenic tenside is 1:10-200:0.1-10:0.2-5, continues to stir, and is heated to 70 ℃~95 ℃, centrifugal, collect the protoheme crystallization, wash after drying with water, get the finished product protoheme;
4) regulating step 2) pH of gained filtrate to neutral, concentrate, dry, globulin powder must decolour.
Among the present invention, said oxyphorase raw material is livestock blood or is oxyphorase, anticoagulated blood, clot, globulin powder or the blood cell of livestock blood processing.
Among the present invention, proteolytic ferment do not had special requirement, as long as the proteolytic enzyme of energy hydrolysis oxyphorase is all available, stomach en-, trypsinase as animal-origin, the papoid of plant origin, bromeline, microbe-derived animal proteolytic enzyme (production of Nanning Pang Bo bio tech ltd), food flavor enzyme or the like can be with any or its mixtures in above-mentioned.Because animal proteolytic enzyme and food flavor enzyme low price, easy to use and commercial production marketing, preferred animal proteolytic enzyme and food flavor enzyme, perhaps both mixed enzyme arranged.
In order to eliminate protease activities, to improve the quality of products, further feature of the present invention is the enzymolysis solution that step 1) obtains to be heated to keep 20 minutes inactivated proteases more than 90 ℃.
Among the present invention, said nonionogenic tenside is a kind of or its mixture among alkylphenol polyoxyethylene, fatty alcohol-polyoxyethylene ether, tween and the Si Pan.Because tween is extensive use of in daily life as foodstuff additive, its security obtains proof already, and preferred tween is as the tensio-active agent of crystallization protoheme.
The mass concentration of used concentrated hydrochloric acid is 35%~38% among the present invention.
The inventive method is before the crystallization protoheme, and the oxyphorase enzymolysis is micromolecular albumen, and thermostability improves, not can with the protoheme co-precipitation; By regulating the pH value of enzymolysis solution, most albumen is separated with protoheme, the protoheme crystallization just than being easier to, is reacted easier operation like this, and whole process does not need special equipment, does not need to add crystal seed yet.
The decolouring protein powder color and luster that the present invention obtains is good, and impurity is few, and protein content reaches about 95%, can be used for foodstuff additive.
The inventive method is simple to operate, with low cost, can utilize the oxyphorase that extracts behind the superoxide-dismutase (SOD) as raw material, unite and extract protoheme and food grade decolouring globulin powder, thereby realized the comprehensive utilization of livestock blood, do not have waste, cleanliness without any pollution is applicable to suitability for industrialized production.
