Abstract

A kind of selenium strengthens the production method of straight rice-flour noodles, using rice as primary raw material, after soaking, crushing, sodium selenite is added during breading, adjust moisture content, through twin-screw extruder, aging, it is multiple steam, the processes such as microwave and ultrasound is handled, washed and dressed, most afterwards through drying, cutting, packaging and obtain.Of the invention is unique in that, rice flour is handled in ageing process using Catalyzed by Ultrasonic Wave, using microwave and ultrasound superposition in rice flour after multiple steaming.Ultrasonic wave has intensified the rearrangement of starch molecule in rice flour during constantly vibrating and beaing, and the superposition of microwave and ultrasound promotes the combination of plasma selenium and starch molecule.There is chewy texture through rice flour produced by the present invention, sodium selenite is tightly combined with starch molecule, and human body easily absorbs, and retention rate is high after boiling.

Description

A kind of selenium strengthens the production method of straight rice-flour noodles
Technical field
The present invention relates to the production methods that a kind of selenium strengthens straight rice-flour noodles, belong to field of agricultural products processing.
Background technique
Rice flour be it is deep liked by people, time-honored traditional food.Currently, rice flour on the market is only original with rice Material, nutritional ingredient is more single, is unable to satisfy the growing nutritional need of people.It is asked for rice flour nutritive value is not high Topic adds the method for nutrient during having scholar using production rice flour to improve nutritive value, but major part is produced The rice flour come is not close in conjunction with nutrient, is easy to be lost during the cooking process, the practical retention rate of nutrient is low.Therefore, nutrition The boiling retention rate of rice flour restricts always the development of ourishing rice flour.
Selenium has inoxidizability, and body can be protected from free radical and carcinogenic infringement, also can reduce inflammatory reaction, increases Strong immunity is metabolic necessary material to resist infection, the health for promoting heart, the effect for enhancing vitamin e.Intake It is insufficient the reaction such as prematurely senile, cataract, hypertension easily occur.According to national relevant regulations, can be added in cereal and its product Sodium selenite supplements selenium element, and the maximum allowable usage amount in terms of elemental selenium is that (selenium contains in sodium selenite by 140-180 μ g/kg 45.7%) amount is.
Summary of the invention
Have the defects that easy loss, boiling retention rate are low for the ourishing rice flour of prior art production, one kind is now provided The method that the conjugation and nutrient boiling retention rate of nutrient and rice flour can be promoted.
A kind of selenium strengthens the production method of straight rice-flour noodles, it is characterised in that the following steps are included:
(1) raw material soaking: choosing early rice, eluriate 3 times or more, 3-4h is impregnated in 30-36 DEG C of water;
(2) it crushes: being filtered dry moisture, crushed with 60 mesh mesh screen beater disintegrating machines, rice flour crosses 80 mesh mesh screens;
(3) breading: being slowly added to drinking water and sodium selenite into the rice flour crushed, is uniformly mixed using mixer, Adjusting rice flour moisture content is 32-36%, and mixer revolving speed 1500-1600r/min, the breading time is 8-10min, sodium selenite Additive amount be 120-130 μ g/kg rice flour;
(4) it squeezes: the material mixed is subjected to squeezing powder by twin (double) screw extruder;
(5) aging: the rice stick squeezed out is placed in aging 5-6h in the environment of 32-36 DEG C of temperature, humidity 75-80%, aging Rice flour is acted on using the ultrasonic wave of frequency 400-450KHz, power 200-220W in the process;
(6) multiple to steam: rice stick being sent into steamer, steams 2-3min again;
(7) microwave and ultrasound is handled: the rice stick of multiple steaming is sent into the environment of humidity 95-98%, using microwave and Ultrasonic wave superposition acts on rice flour, time 2-3h, and temperature is controlled at 50-55 DEG C;Ultrasonic frequency is 340-360KHz, power For 160-180W;Microwave frequency is 2450MHz, power 70-75W;
(8) wash and dress: treated rice stick is put into pond immersion 18-20min, remove it is remaining on rice flour spit slurry, it is outstanding Hang combing;
(9) dry: control rice flour water content is in 13-14%;
(10) it cuts, pack.
The difference of present invention process and the prior art is:
1, a certain amount of sodium selenite is added during producing rice flour, increased by squeezing, in ageing process super Sonicated, ultrasonic wave have intensified the rearrangement of starch molecule in rice flour during constantly vibrating and beaing.
2, for the binding characteristic of selenium and starch, microwave and ultrasound superposition is used after multiple steaming, promotes plasma selenium It with the combination of starch molecule, enhances rice flour and squeezes the network structure to be formed, enhance the toughness of rice flour, it is existing to avoid easy broken strip As.
3, the present invention realizes combining closely for rice flour and sodium selenite, and rice flour obtained has chewy texture, the synthesis product of rice flour Matter gets a promotion, and nutrient boiling retention rate is high.
