Background technology
Rice is the main food of our people, domestic some rice processing enterprises, in order to improve the class of rice, is used for reference External advanced experience, is proposed the polished rice processing technique of suitable for China, and the quality of the rice for being processed has very big Improve.But, the Keep the quality and freshness phase of its rice for processing is all shorter, particularly a shelf-life slightly mistake, once Kaifeng Packaging bag, the rice in bag is just particularly easy to infested, has both affected mouthfeel, is also harmful to health.
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art, there is provided a kind of processing technology of prolongation rice shelf-life, energy The growth of enough effectively suppression microorganisms, extends the shelf-life of rice, and can lift the nutritive value of rice.
To achieve these goals, the present invention is adopted the following technical scheme that:
A kind of processing technology for extending the rice shelf-life, comprises the following steps:
(1) clear up:The boosted machine of paddy carries out just clear, removing impurity into vibrating cleaning sieve, then the vibration of Jing seconds is clearly Reason sieve is carried out again clearly, and Jing stone removers remove stone, then carries out magnetic separation, rejects magnetic impurity;Rice husk separation is carried out again, obtains paddy rough Thing;
(2) spraying profit is rough:The rough process of spraying profit is carried out using atomization spraying machine, allows the water tariff collection contained by the rough thing of paddy to exist 13-15%, then carries out out rough and pearling;Thereafter, hot polishing is carried out while hot, is cooled down, carry out selected, obtain selected rice;
(3) dispensing:Raw material is taken by following weight portion:Selected rice 80-100 parts, corn flour 10-20 parts, complex denaturation rice Starch 10-15 parts, efficient fresh-keeping agent 0.01-0.05 parts;
(4) granulate:Raw material is mixed, is stirred, carry out extrusion, crushed, then made using rotary granulator Grain obtains wet grain into rice-shaped;
(5) curing is bakeed:Wet grain is placed in 100-120 DEG C of drying box, is dried to water content below 10%, in closed appearance Room temperature is cooled in device;
(6) ultraviolet irradiation:The dried grain of rice is entered into ultraviolet irradiation process, using ultraviolet sterilization worm device, its Uitraviolet intensity 200-300W, wavelength 240-280nm;
(7) it is vacuum-packed.
Complex denaturation rice starch described in step (3) is prepared by following methods:16-20 is configured to by raw material of rice starch The rice starch breast of Baume degrees, is heated to 60-80 DEG C under the alkalescence condition of PH8, adds the trichlorine of rice starch breast weight 0.15% Oxygen phosphorus reaction, adds the aceticanhydride reaction of rice starch breast weight 3%, washs after cooling, is dehydrated, is dried, and sieves to obtain complex denaturation Rice starch.
Efficient fresh-keeping agent described in step (3) is prepared by following methods:By weight percentage by 10% monoglyceride, 20% D-sorbite and 20% sucrose ester mix, 60-80 DEG C of heating, and stir to obtain oil phase compound;By 10% citric acid, 20% mountain Potassium sorbate, 10% calcium propionate mix with 10% water, 60-80 DEG C heating, stir water mixes material;Then by above-mentioned oil phase Compound is mixed with water conjunction material and carries out vacuum emulsification and obtain final product efficient fresh-keeping agent.
Compared with the prior art, beneficial effects of the present invention are as follows:
The processing technology of the prolongation rice shelf-life of the present invention, can effectively suppress the growth of microorganism, extend rice Shelf-life, and the nutritive value of rice can be lifted.The present invention is added with rice and ultraviolet irradiation process, has both been improve big The nutritive value of rice, lifts rice mouthfeel, and the shelf-life of prolongation rice, and complex denaturation rice starch is added during dispensing, can Suppress the growth of microorganism, antiageing effect is good, extend the shelf-life of rice;The antistaling agent of addition is safe efficient, the shelf-life It is long;Rice after assorted, into ultraviolet irradiation process, using ultraviolet sterilization worm device, can destroy bacterium and larva is thin DNA in born of the same parents, so as to kill rice in remaining worm's ovum and germ, to extend the Keep the quality and freshness phase of rice, and ensure edible defending Raw safety, is conducive to health.
Specific embodiment
With reference to embodiments the present invention is further illustrated, but the present invention is not limited only to these embodiments, not On the premise of departing from present inventive concept, any improvement made is within the scope of the present invention.
