Description
Technical field
The invention belongs to grease processing technology fields, and in particular to zearalenone toxin is de- in a kind of maize germ
Except method.
Background technique
Zearalenone is generated by Fusarium graminearum and the metabolism of soybean sickle-like bacteria, is most normal in corn and its product
See and most intractable mycotoxin.China is world food big producer, corn as the big staple food crop in China three it
One, the 30% of total output is used for the raw material of industry, and 60% is used as grain ration and seed for agriculture feed, remaining 10%.Corn
The pollution of mould, especially sickle-like bacteria is highly prone to during producing, receiving, process, transport, store.Gibberella zeae alkene
Ketone can inhibit activity of NK cell etc. to influence the immune system of animal and human body by the activity of inhibition T or bone-marrow-derived lymphocyte.
Zearalenone can weaken the activity of animal body inner estrogen in conjunction with internal estrogen in animal body, cause animal raw
The disorder for growing function influences the reproductive development of animal.
The removing process of zearalenone will generally follow the following: 1, not changing grain, feed and human food
Nutritive peculiarity；2, it quickly and effectively can remove or destroy zearalenone；3, in processed grain, feed or food
In do not generate the residual or carcinogenicity/mutagenesis residue of noxious material；4, technically feasible, economically there is Affording acquisition,
The cost of final products cannot be significantly affected.
Radiotechnology be commonly handle in recent years grain, in food and feed mycotoxin research hotspot, radiation pair
The degradation effect of aflatoxin B1 is preferable, but little to the effect of zearalenone.Adsorption technology can preferably reduce grain
Zearalenone in food crop, but it is easily introduced exogenous material, feed or food itself are destroyed to a certain extent
Nutritive value.
Summary of the invention
According to the above-mentioned deficiencies in the prior art, the object of the present invention is to provide zearalenones in a kind of maize germ
The removal methods of toxin reduce the zearalenone in maize germ cake and crude oil, are reducing the same of the pollution of mycotoxin
When, it keeps its nutritional ingredient not to be destroyed, improves raw corn oil quality.
The removal methods of zearalenone toxin in maize germ of the present invention are as follows: measured maize germ,
It clears up, is crushed, high temperature and high pressure steam detoxification, softens, rolling embryo, squeezing liquefaction, obtaining corn squeezing crude oil.
The removal methods of zearalenone toxin, include the following steps: in the maize germ
(1) maize germ is measured；
(2) maize germ after metering is cleared up into removal of impurities；
(3) by the maize germ after cleaning removal of impurities using broken crusher machine；
(4) by broken maize germ 150~180 DEG C, steam pressure be 0.8~1.2MPa under conditions of take off
Poison；
(5) maize germ after detoxification is softened, moisture control is 10~12% after softening；
(6) maize germ after softening is carried out rolling embryo, obtains oil plant embryo piece；
(7) the oil plant embryo piece that embryo obtains will be rolled to squeeze, obtains corn squeezing crude oil.
Wherein:
It is the first squeezing rate in order to calculate crude oil to maize germ metering.
The cleaning removal of impurities are as follows: firstly, Ferromagnetic Impurities in maize germ are removed using magnetic separator, subsequently into vibration
Classifying screen removes the impurity such as stone and the maize peel in maize germ.Oil circuit is blocked to prevent impurity, or influences oil quality.
Gap of tooth roller is 2.5~3.5mm on the crusher, lower gear roller gap is 1.5~2.5mm.After broken
Increase oil surface product, conducive to the transmitting of temperature and moisture when softening.
The softening temperature is 50~70 DEG C.Finally have and suitably may be used so that plumule has certain moisture and temperature
Plasticity.
The embryo temperature of rolling is 35~45 DEG C.By destroying the eucaryotic cell structure inside plumule, reduces material thickness, make embryo
Bud reaches maximum consistency.
The oil plant embryo piece is with a thickness of 0.35~0.45mm.So that extrusion embryo piece organoleptic requirements are thin and even, it is few at powder, no
Oil leak, not material leakage.
The pressing temperature is 75~85 DEG C.So that the grease squeezed keeps natural, nutriment is not lost, and does not generate
Carcinogenicity substance polycyclic aromatic hydrocarbon.Squeezing process originally must steam stir-fry plumule, to increase oil yield, but will cause at that rate
BaP it is exceeded, the pressing temperature that the application uses can reduce the generation of BaP.
Compared with prior art, the beneficial effects of the present invention are:
The present invention using physical method removing maize germ in zearalenone, hence it is evident that reduce maize germ cake and
The content of zearalenone in crude oil is squeezed, removal rate does not destroy the structure of triglycerides up to 85% or more, does not introduce outer
Property impurity in source retains nutritional ingredient intrinsic in raw corn oil, and vitamin E is up to 1300mg/kg or more, phytosterol in crude oil
Up to 12500mg/kg or more.
