Abstract
The present invention provides a kind of degradation removal methods of the secondary derivatives of mycotoxin in grain and its product, and high pressure swelling detoxification is carried out by the way of stage boosting using high-temperature high-pressure swelling machine, after cyclone separator cools down precipitation, obtain the broken product of grain.Detoxification efficiency of the present invention is good, the structure of deoxynivalenol, zearalenone and aflatoxin B1 can be destroyed simultaneously, make the reduction of its content, it avoids and carries out the problem of toxin removing needs material carrying out basic treatment using high-temperature high-pressure swelling machine, into without subsequently carrying out acid adjustment to the product after detoxification.Step is simple, easy to operate, can be mass-produced.
Description
Technical field
The invention belongs to a kind of secondary generations of mycotoxin in foodstuff processing technology field more particularly to grain and its product
Thank to the degradation removal methods of derivative.
Background technology
Cereal crops are the high-incidence seasons for infecting mycotoxin in growth period, maturity period and harvest time, in growth period, soil
In mycotoxin fruit is absorbed by root system, in the maturity period, especially in Basin of Huaihe River, run into plum rain season, rainwater
Into in seed shell, grain is particularly easy to obtain head blight, and grain seed is easy for infection mycotoxin, in harvest time, due to temperature
Degree is high, humidity is big, and for grain seed particularly corn in plumule portion, moisture is big herein, and rich in fat, protein and starch, is
The good culture medium of mycotoxin.According to grain sanitary survey data, 2010-2013 central plain areas corn contaminant toxin
Ratio in 40-80% or so, improve year by year later, 2016 and the new harvesting corn mycotoxin in some areas in 2017 it is exceeded
Rate is 11% and 32% or so.
The cometabolism derivative of mycotoxin mainly has deoxynivalenol in grain（Vomitoxin,
Deoxynivalenol, DON）, zearalenone（Zearalenone, ZEA）And aflatoxin B1（Aflatoxin B1,
AFB1）, easily it is present in grain and its fabricated product.Extensive poisonous effect can be generated to people, animal, such as appetite reduction, body
Mitigation, metabolic disorder etc. again.
According to GB2761-2017《Mycotoxin is limited the quantity in national food safety standard food》Defined grain and its system
The highest Limited Doses of product, deoxynivalenol≤1000ug/Kg, the ug/Kg of zearalenone≤60, aspergillus flavus poison
The ug/Kg of plain B1≤20.
《The law of food safety》Regulation, sanitary index are exceeded（Containing mycotoxin）Grain must not be used as raw-food material.At present
Mainly there are physisorphtion, chemical reaction to the removal methods of the secondary derivatives of mycotoxin in grain and its product both at home and abroad
Method and biological detoxication method.Physisorphtion be by add inorganic mineral adsorb grain in deoxynivalenol,
Zearalenone and aflatoxin B1, but the minerals adsorbed after taking off will be also discharged into external environment, cause secondary dirt
Dye.Chemical reaction method meets alkali using deoxynivalenol can decompose the principle of inactivation, using sodium hydroxide, ozone or ammonia
Deoxynivalenol is destroyed, to achieve the purpose that degradation removing, but adds in the chemical reagent in grain and its product, meeting
Seriously affect the quality of grain and processing performance and food（It raises）With quality, the quality safety of downstream product is influenced, and is difficult shape
It is into large-scale production, chemical method is to other toxic effect unobvious.Microbial detoxification method is turned using the biology of some biological enzyme
Change acts on, and deoxynivalenol, zearalenone and aflatoxin B1 is made to destroy or be changed into low toxicity material
Method, microbial detoxification method need to crush in grain, are fitted into retort the addition liquid biological enzyme under the conditions of water phase, make material
It is come into full contact with enzyme, reaches degradation purpose, but the removing of moisture causes the waste of the energy, and it is difficult to large-scale production.
The content of the invention
Difficulty is removed for the secondary derivatives of mycotoxin in grain and cereal product, and removal effect is bad or is difficult to
The problem of large-scale production, the present invention provides a kind of degradation removings of the secondary derivatives of mycotoxin in grain and its product
Method, degradation removal methods comprise the following steps：
（1）Grain is first cleaned, then by impact machine, removes surface mildew, obtains pretreatment grain；
（2）The pretreatment grain is crushed to 10-80 mesh through pulverizer, it is broken to obtain grain；
（3）By the broken feeding tempering tower of the grain, the saturated vapor of 0.4-0.6MPa is continually fed into tower, tempering tower plus
The saturated vapor of 0.4-0.6MPa is passed through in thermosphere, temperature in tower is made to reach 60-80 DEG C, is discharged after 1-2h, obtaining moisture is
The quenched grain of 13-15% is broken；
（4）It is delivered in high-temperature high-pressure swelling machine by double-layer seal auger by the quenched grain is broken, high-temperature high-pressure swelling machine
High-temperature high-pressure swelling detoxification is carried out by the way of stage boosting, it is broken that detoxification grain is made in outlet pressure 1-1.3MPa；
The saturated steam of 0.4-0.6MPa is passed through in wherein described transmission process into the interlayer of sealing auger, is kept in sealing auger
The broken temperature of grain for 60-80 DEG C, the saturated steam of 0.4-0.6MPa is passed through into sealing auger, makes the broken moisture of quenched grain
For 15-18%.
（5）The detoxification grain is broken after cyclone separator cools down precipitation, obtain the broken product of grain.
Further, step（4）Described uses stage step-up method to boost to 0.6-1MPa for the first stage, into
Row second stage is boosted, and second stage boosts to 1-1.3Mpa；Wherein, the first stage pressure is reached by physical impact,
