Description

A kind of low glycemic index grain rice and its production method
Technical field
The present invention relates to food processing field, particularly a kind of low glycemic index grain rice and its production method.
Background technology
As the crowds such as social development, hyperlipidemia, obesity increasingly increase.Blood glucose after the common staple food such as rice, steamed bread is edible Index is higher, and about 80~88.Lack the staple food species of diabetes patient in the market.
After corn adopts conventional method ripening, the abundant gelatinizing of starch, the starch enzymatic degradation in being easy to by digestive tract after eating, Make glycemic index higher, be unfavorable for diabetes patient.
After age of starch, molecule chain rigidity increases, some generation crystallizations, is unfavorable for diastatic effect, can reduce blood Sugared index.But the reduction of glycemic index is limited.
The starch of different degree of agings, larger degree of aging, resistance can be obtained by the environmental condition for controlling starch Content of starch increases, the starch-based product low so as to obtain glycemic index.
Content of the invention
Present invention is primarily targeted at a kind of low glycemic index grain rice and its production method are provided, effective comprising full paddy Nutritional labeling, while glycemic index is low.
Technical scheme is as follows:
A kind of low glycemic index grain rice, below 50, the corn is the glycemic index of the low glycemic index grain rice Semen Coicis or Semen Maydiss or Semen setariae or red rice or fructus zizaniae caduciflorae or its combination.
The production method of described low glycemic index grain rice, the method comprising the steps of:
1) corn is carried out water immersion, dewatering obtains material 1;
2) carry out adding cooking liquor to carry out ripening by material 1, filter out cleaning waste water, obtain material 2;
3) material 2 is carried out burin-in process, obtains material 3;
4) material 3 is dried;
Complete the making of low glycemic index grain rice.
Preferably, the step 1) 5-35 DEG C of immersion 2-24h of 2-5 times of water.
It is further preferred that the immersion process 100~1000W/kg ultrasonic Treatment 0min~5min, stops ultrasound Ripple 5-30min, repeated action is until immersion terminates.
Preferably, the step 2) cooking liquor is tap water or acid water, Fructus Citri Limoniae of the acid water for 0.01%-3% Acid or or lactic acid or aqueous acetic acid.
Preferably, the step 2) cooking conditions be material 1 in add 1-1.5 times of cooking liquor, in 70~120 DEG C process 10-50min, cold water drip washing stand.
It is further preferred that the static conditions are in 20-50 DEG C, relative humidity stands 0.1-24h 80%~90% time.
Preferably, the step 3) aging condition is:Microwave dose 0.005-0.01w/g, processes 0.1- by 40-50 DEG C 0.5h after 30-50 DEG C stand 0.5-2h, 1-5 time repeatedly.
Preferably, the step 4) drying condition is:Microwave dose 0.05-0.5w/g, processes 3-30min, makes water content Less than 18% is reached, then at 20-60 DEG C of hot air drying, until water content reaches less than 14%.
The present invention provides a kind of low glycemic index grain rice and its production method, has the beneficial effect that:
1st, the low glycemic index grain rice that the present invention is provided includes the effective nutritional labeling of full paddy, while will not be notable after edible Lift blood sugar for human body index.
2nd, the manufacture method that the present invention is provided can improve the mouthfeel of corn rice, while can cut down by weak acid cooking aging The antinutritional factor of Quan Guzhong.
3rd, make starch gelatinization more abundant using acid water in cooking aging, abundant gelatinizing is conducive to preferably aging.
4th, the ultrasonic Treatment of immersion process may advantageously facilitate the infiltration of moisture, shorten soak time, meanwhile, ultrasound wave has Beneficial to the dissociation of starch and the protein of combined state in natural grain, so as to improve disappearing for product resistance content of starch and protein Rate.
5th, the standing process after ripening, starch molecule ordered arrangement form crystal, are conducive to the generation of resistant starch, form sediment Powder enzyme effect is difficult, declines glycemic index.
6th, using aging middle employing microwave technology in corn rice first, the non-thermal effect of microwave is made full use of to act on paddy Polar group in thing molecule, makes starch sufficient crystallising, induction cereal starch generate resistant starch, reduce product glycemic index.
7th, microwave-hot blast combination drying is adopted, in the ordered arrangement that dry run microwave further results in starch, is promoted anti- The generation of property starch.Microwave-hot blast combination drying time is short, and the loss of the nutrient substance such as vitamin is few, while to harmful microorganism Killing action is strong, and bacteria reducing works well, and is conducive to the shelf-life for extending corn rice.
8th, the low glycemic index grain rice hardness of present invention offer, elasticity, cohesion are suitable with commercially available Nutritive Rice, and albumen Matter digestibility and resistant starch ratio are above commercially available Nutritive Rice or coarse cereals rice.
