Abstract
The invention discloses a kind of application of starch aspect reduction monascorubin photofading of bringing back to life, and there is the preparation method of the monascorubin product of anti-light radiation effects. The method is: in the starch of bringing back to life, add the monascorubin aqueous solution, the monascorubin aqueous solution is adsorbed in completely and brings back to life in starch, obtain having the monascorubin product of anti-light radiation effects. The diffraction of the crystal that utilization of the present invention is brought back to life in starch to ultraviolet light, make to cause the ultraviolet energy of monascorubin photofading not absorbed by monascorubin, thereby avoid the photochemical reaction of monascorubin, finally improve the anti-light radianting capacity of monascorubin. Anti-light radiation effects is stable, effective.
Description
Technical field
The present invention relates to technical field of food biotechnology, particularly relate to one and bring back to life starch in reduction red colouring agent for food, also used as a Chinese medicine rednessThe application of element photofading aspect, and there is the preparation method of the monascorubin product of anti-light radiation effects.
Background technology
Monascorubin is a kind of pigment of monascus growth course secretion, the meeting under light radiation condition of this pigmentFade gradually, wherein, ultraviolet ray is to cause the main light wave of monascorubin photofading.
At present, reduce or avoid in the method that monascorubin fades, one is to absorb light at monascorubinCan after improve the ability of the anti-light radiation of monascorubin, these methods by controlling photochemically reactive processOnly make the monascorubin photofading reaction time extend, can not avoid monascorubin photofading to occur.
Reducing or avoiding the another kind of method that monascorubin fades is to add amino in monascus culture mediumAcid, perilla leaf extract, add cysteine, arginine and serine, vitamin C, quercitrin in pigment solutionKetone, Isosorbide-5-Nitrae, 6-trihydroxynaphthalene etc. improves the anti-light radianting capacity of monascorubin, but does not all obtain idealEffect.
Summary of the invention
The object of the invention is for the technological deficiency existing in prior art, and provide the one starch of bringing back to life to existReduce the application of monascorubin photofading aspect.
Another object of the present invention is to provide a kind of system of the monascorubin product with anti-light radiation effectsPreparation Method.
For realizing the technical scheme that object of the present invention adopts be:
Bring back to life starch in the application reducing aspect monascorubin photofading, and the starch of bringing back to life is for reducing redBent haematochrome photofading.
There is a preparation method for the monascorubin product of anti-light radiation effects, in the starch of bringing back to life, addThe monascorubin aqueous solution, is adsorbed in the monascorubin aqueous solution completely and brings back to life in starch, obtains having anti-The monascorubin product of thermal effect. Wherein, the monascorubin addition that look valency is 100U/g is for dryThe 20-60%(mass ratio of starch (referring to for the preparation of returning farinose raw starch)).
Wherein, the monascorubin that look valency is 100U/g and the mass ratio of dried starch are preferably 1:5-3:5.
In the time that needs products therefrom is dry, obtain having the monascorubin product 60 of anti-light radiation effectsDEG C be dried to constant weight.
The described starch of bringing back to life can adopt the method for prior art to obtain. Concrete grammar is:
Starch emulsion, in 90-98 DEG C of gelatinization 30min, is carried out to high temperature high pressure process afterwards, afterwards, at 0-4DEG C aging 96-120h, obtains the starch of bringing back to life; The temperature of described HIGH PRESSURE TREATMENT is 120-125 DEG C, vapour pressure0.1 pound/square centimeter of power, the time of HIGH PRESSURE TREATMENT is 30-60min.
The described starch of bringing back to life also can be prepared by following method:
(1) by starch emulsion in 90-98 DEG C of gelatinization 30min, carry out afterwards high temperature high pressure process, afterwards,At 0-4 DEG C of aging 96-120h, obtain the starch of bringing back to life; The temperature of described HIGH PRESSURE TREATMENT is 120-125 DEG C,0.1 pound/square centimeter of steam pressure, the time of HIGH PRESSURE TREATMENT is 30-60min;
(2) step (1) gained is brought back to life starch crushed after being dried, obtains the powdery starch of bringing back to life.
Wherein, preparing back farinose raw material is that cornstarch, farina, sweet potato starch or wheat form sedimentPowder.
A preparation method with the monascorubin product of anti-light radiation effects, comprises the steps:
(1) by starch emulsion in 90-98 DEG C of gelatinization 30min, carry out afterwards high temperature high pressure process, obtainGelatinized corn starch; The temperature of described HIGH PRESSURE TREATMENT is 120-125 DEG C, 0.1 pound/square centimeter of steam pressure, high pressureThe time of processing is 30-60min;
(2) in the gelatinized corn starch obtaining in step (1), add the monascorubin aqueous solution, make monascorubinThe aqueous solution mixes with gelatinized corn starch, then at 0-4 DEG C of aging 96-120h, obtains having anti-light radiation effectsMonascorubin product.
In the time that needs products therefrom is dry, obtain having the monascorubin product 60 of anti-light radiation effectsDEG C be dried to constant weight.
Compared with prior art, the invention has the beneficial effects as follows:
1, the diffraction of the crystal that utilization of the present invention is brought back to life in starch to ultraviolet light, makes to cause monascorubinThe ultraviolet energy of photofading can not be absorbed by monascorubin, thereby avoids the photochemistry of monascorubin anti-Answer, finally improve the anti-light radianting capacity of monascorubin.
2, the starch of bringing back to life that the present invention adopts for reducing monascorubin photofading is wholefood, asThe protective agent of monascorubin is unrestricted, conveniently in the food such as ham sausage, fermented bean curd, adds. The starch of bringing back to lifeHigh temperature resistant processing is added crystal thawing can not occurred in food processing, has permanent protection monascorubinThe effect of light radiation.
3, method gained of the present invention has in the monascorubin product of anti-light radiation effects, and the starch of bringing back to life originallyBody has Constipation, controls blood sugar, improves the effects such as immunity, can improve and use monascorubin foodFunction.
4, preparation method's technique of the monascorubin product with anti-light radiation effects of the present invention is simple, holdsEasily realize, cost is low.
5, in the preparation method of the monascorubin product with anti-light radiation effects of the present invention, red in order to makeBent haematochrome molecule enters brings back to life in starch crystal, soluble in water monascorubin joining brought back to life in starch,Pigment, under the effect of water, enters bring back to life in starch crystal completely, and anti-light radiation effects is stable, effective.
