Abstract

The invention provides a production method of milled germ-retaining germinated rice, which mainly comprises the following steps: selecting unhulled rice, hulling rice, removing impurities, screening to obtain high-grade brown rice, classifying, cleaning and sterilizing, soaking, germinating, rinsing, drying, lightly grinding by a germ preserver, coating by chitosan, and drying to obtain the milled germ-retaining germinated rice. The method has simple process, reduces the microbial contamination in the germinating process and solves the difficult problems of cracking, brown stains, easy overcooking, and the like in the drying process; and the milled germ-retaining germinated rice is better than germinated brown rice on the taste and accordant with green producing requirements, and has good colors and taste, rich nutriments and strong heath care function.

Description

A kind of production method of milled germ-retaining germinated rice
Technical field
The present invention relates to a kind of production method of milled germ-retaining germinated rice.
Background technology
The mouthfeel of the existing highed milled rice of milled germ-retaining germinated rice has the health care of sprouted unpolished rice again, and the physiological function that the milled germ-retaining germinated rice tool is superior: (1) milled germ-retaining germinated rice is processed by sprouted unpolished rice, has kept the nutritional labeling of plumule; (2) be rich in GABA (GABA), GABA has activation brain blood flow, strengthens the brain cell metabolism, hypotensive, anticonvulsion, promote long-term memory, improve liver, renal function, alleviation artery sclerosis, reduce neutral fat, prevent function such as obesity.(3) contain IP6 (IP-6), glutathione, have powerful oxidation resistance and the effect that banishes the feeling of languor; (4) be rich in lipotropism matter oxidation material (containing abundant lipotropism matter oxidation material in the sprouted unpolished rice) as forulic acid, phytic acid, oryzanol, triolefin tocopherol etc.; (5) be rich in food fiber; (7) the milled germ-retaining germinated rice production technology will solve the difficult problem of sprouted unpolished rice taste bad will, in the germination process, enzyme has destroyed the hard particles that nutritional labeling and ANFs-phytic acid are combined together to form, the absorptivity of nutritional labeling significantly improves, so the local flavor after the milled germ-retaining germinated rice boiling is better than sprouted unpolished rice and milled germ-retaining rice.
The processing method of existing germinated rice comprises cleaning, immersion, germinates and drying, and germination percentage is low, environmental pollution is serious, product quality is not high.
Summary of the invention
The technical problem to be solved in the present invention is: for overcoming the deficiencies in the prior art, obtain the pure white germinated rice of high-quality, propose a kind of production method of pure white germinated rice, method is easy, pollution is little, germination percentage is high.
Technical scheme of the present invention is: a kind of pure white germinates and protects the production method of embryo rice, may further comprise the steps:
(1) classification: select for use when producing fresh paddy rice huller paddy per year and obtain brown rice, it is standby to select the intact brown rice of guarantor's embryo;
(2) sterilization: above-mentioned brown rice with the ozone water solution soaking disinfection of 1.0mg/kg~1.5mg/kg 2 minutes~5 minutes, is drained;
(3) soak: the brown rice after the sterilization soaked 20 hours~30 hours in clear water or mass percent are the gibberellin aqueous solution of 0.005-0.015%;
(4) germinate: the brown rice after will soaking is 25 ℃~30 ℃ cultivations, and incubation time is 20 hours~30 hours, makes the long 0.5mm~1.0mm of being of bud of gained sprouted unpolished rice;
(5) drying: above-mentioned sprouted unpolished rice is carried out drying with 50 ℃~60 ℃ temperature, to moisture be 17%~18%;
(6) film: the acetic acid with 1%-3% is solvent; the preparation mass percent is the solution of 1%~2% shitosan and 0.1%~0.2% sodium ascorbate; with above-mentioned solution dried sprouted unpolished rice is filmed; and be 12%~15% at 40 ℃~60 ℃ temperature low temperature drying to moisture; make its surface form the diaphragm of layer of transparent light, promptly get the pure white germination and protect embryo rice.
Wherein, the described brown rice of step (1) is the raw material of germination usefulness.
The described ozone solution of step (2) is produced by electrolysis type ozone generator.
Described dry normal pressure of step (5) or vacuum drying.
The described coating method of step (6) is that sprouted unpolished rice is immersed in the described solution, pulls out again; Or sprouted unpolished rice is sprayed with described solution.
The process route of technical scheme of the present invention can be summed up as: paddy → rice huller paddy → removal of impurities → screening → high-quality brown rice → classification → cleaning → sterilization → immersion → germination → washing → drying → guarantor's embryo machine gently grinds → chitosan coating → drying → milled germ-retaining germinated rice.
The brown rice that the present invention is produced with paddy is the germination raw material, obtains protecting the intact brown rice of embryo through protecting the embryo machine after the low temperature drying; Use the ozone solution soaking disinfection, reduced the pollution of assorted bacterium and the use of clorox, meet green requirement of producing; Brown rice after the sterilization is processed into the complete guarantor's embryo sprouted unpolished rice of plumule; Utilize solubility in acid shitosan and sodium ascorbate to film, solved the brown stain of dry run, a quick-fried waist difficult problem, solved simultaneously and stuck with paste mashed problem when cooking protecting the embryo germinated rice; Obtain milled germ-retaining germinated rice behind the dried coating film, be rich in the health care rice of physiological activators such as GABA.Its leading indicator has: germinate and protect the embryo rate more than 95%, GABA>60mg/100g rice, moisture about 15%.
The production method of germinated milled rice provided by the invention is easy, pollution is little, germination percentage is high; It is nutritious that embryo rice is protected in the pure white germination of being produced, and health care is strong, and mouthfeel is better than sprouted unpolished rice and milled germ-retaining rice.
The specific embodiment
Embodiment 1:
Bright paddy obtains brown rice through rice huller paddy.Got in the ozone water solution that the complete brown rice of profile cleaned, was immersed in 1.0mg/kg 2~5 minutes, in clear water, soak after 24 hours, in cultivating about 24 hours at 25 ℃, form the germinated rice of the long 0.5~1.0mm of bud, germinated rice adopts 50~60 ℃ temperature to carry out the sprouted unpolished rice that low temperature drying obtains moisture 17%~18%.Soaked 2 minutes with the sodium ascorbate solution (1% acetic acid is solvent) that contains 2% shitosan and 0.2% then, dry back forms the adventitia of transparent light, and the pure white that obtains moisture 15% germinates and protects embryo rice.
Embodiment 2:
