Description
Technical field
The present invention relates to paddy husk rice fields, and in particular to a kind of high-efficiency soft husk rice method.
Background technology
Rice is the staple food of southerner, and good rice needs the processing by multiple steps that can just obtain excellent in order to obtain
The rice of matter.Rice processing first has to screen paddy, selects to carry out preliminary cleaning again after good paddy, and
Remove the stone in paddy, avoid adulterating stone in rice.The shell of paddy is sloughed using husking, to the rice of shelling into rice husk
And the separation of rice, the rice of rice husk separation need progress magnetic separation to get rid of the magazines such as the metal fragment in rice.It will be miscellaneous
The rice of the discharges such as matter kibble and essence is ground.Finally rice is polished, is finally packaged.
In paddy husk rice processing, since the moisture of paddy is low, mechanical pressure when grinding except cortex is big, causes to process crisp
Property it is high, easily caused in three traditional rice milling processes the grain of rice fracture, fragmentation, not only influence processing quality of rice, also there are energy
Consume the problems such as high；Part arable land has that agriculture is residual, heavy metal pollution, in rice crop developmental process, these harm members
It is plain to be enriched in paddy kernel cortex more.In rice milling process, husk rice effect can be made to reach best and reduce agriculture to the maximum extent
Residual, heavy metal harm is the important optimization aim of Mill technique.Current line generally makes brown rice of milling using modulation profit rice in the industry
Moisture content reaches 15% or so, and to achieve the effect that improve husk rice, the method is helpful to improving husk rice processing brittleness, but still
The problems such as husk rice caused by can not fundamentally solving when cortex is tough and tensile is difficult.
To improve the problem of milling characteristic of brown rice is difficult, have in industry and water is replaced to brown rice using cellulose or xylan enzymolysis liquid
Infiltration is handled, and under appropriate conditions, is subject to again after the fibrocortex of compact structure is carried out degradation softening by enzyme digestion reaction
It mills, to reducing husk rice pressure, reducing broken rice rate has good result.But this method is improving Mill technique, improves husk rice
Efficiency reduces husk rice cost, improves rice edible safety, and it is preferable not enough to preserve rice nutrition aspect to greatest extent.
Invention content
It is an object of the invention to provide a kind of high-efficiency soft husk rice method, with overcome the deficiencies in the prior art.
The object of the present invention is achieved like this：
A kind of high-efficiency soft husk rice method, it is characterised in that：First use cellulase and the complex enzyme liquid of zytase and protease
Infiltration processing is carried out to brown rice using spray pattern, freezing-microwave thawing processing is then selected, finally carries out husk rice processing, tool
Body operating procedure is：
（1）Steam explosion technology pre-processes：Brown rice is added in a certain amount of distilled water to stir evenly, is put into the place of steam explosion machine
It manages in chamber, is passed through a certain amount of saturated vapor and pressurize certain time carries out steam explosion processing, drying obtains modified brown rice；
（2）Complex enzyme liquid infiltration is handled：Toward step（1）The brown rice surface of steam explosion pretreatment is sprayed centainly in a manner of spraying humidification
Concentration, pH value are 5.0 composite enzyme solution, stir evenly and are placed in 30 DEG C of climatic chamber with double-deck valve bag sealing
Closed processes certain time；
（3）By step（2）Treated that brown rice first carries out freezing processing then carries out microwave thawing for infiltration；
（4）Finally by step（3）Treated, and brown rice carries out light together grind.
The step（1）Middle steam pressure 2.3MPa, dwell time 200s, moisture content 55%.
The step（2）In weigh 200g steam explosions pretreatment brown rice, spray matter to its surface in a manner of spraying humidification
Measure a concentration of 55-65mg/mL, pH value is 5.0 composite enzyme solution, liquid volume added 1.15-1.25%, enzyme processing time 65-75min；
Wherein described complex enzyme liquid cellulase and the mass ratio 1.3: 1: 0.7 of zytase and protease.
The step（2）Middle composite enzyme solution is formulated by the NaAc_HAc buffer solution of pH=4.6-6.5, in 4
Refrigeration is placed spare under the conditions of DEG C.
The step（3）Middle freezing processing carries out under following technological parameter：Cryogenic temperature is -10~-20 DEG C；During freezing
Between be：10-12 hours.
The step（3）Middle microwave thawing processing carries out under following technological parameter：Microwave thawing temperature is 30-60 DEG C；
Microwave thawing power is 600-800W；The microwave thawing time is 10-15min.
The present invention has following advantageous effect：The present invention can destroy the complete table of brown rice peel layer using steam explosion pretreatment
Face makes its surface become loose, forms many holes, convenient for the absorption of misty composite enzyme solution, helps to improve enzymolysis efficiency,
And then improve husk rice rate；It is combined with biological enzyme technology using moisture conditioning technique, is sucked brown rice peel layer using spray pattern
After a small amount of moisture, the binding force with endosperm is reduced, increases the friction between the grain of rice and the grain of rice and is removed the peel to carry out brown rice so as to reduce
It cracks rice, not only reduces meter Wen, lappingout fine grinding can also be carried out to the grain of rice using chaff powder and moisture film, make the pure white beauty of finished product, together
When, cortex is softened by compound enzymatic treatment, brown rice peel layer structure stand composition fiber element, protein etc. are loosened in right amount, is improved
Case hardness；Will infiltration treated that brown rice carries out freezes-microwave thawing processing, effectively destroy epidermal cell structure, it is cold
Jelly can form the big ice crystal of particle, and with the continuous growth of ice crystal, the final denaturation for causing brown rice epidermal cell different degrees of has
Conducive to the disengaging of the grain of rice of epidermis, while using microwave thawing, the time is short, and microwave heating can also eliminate additional enzyme solution residual enzyme
It lives and reduces raw material Initial microorganisms total amount；Three traditional husk rices can be down to one of husk rice by present invention process, reduce husk rice
Husk rice pressure in the process reduces broken rice rate, saves energy consumption, and husk rice is efficient, and shelling rate is fast, ensures the edible safety of rice
Property.
