AI Technical Summary

Technical Problem

The existing germinated brown rice has shortcomings in taste, rehydration performance and industrial cost, and traditional soaking and germination methods have led to nutrient loss and increased wastewater discharge.

Method used

The germination is carried out by micro-spraying and humidification process, combined with steam pregelatinization treatment, and then compounded with residual embryo and refined white rice, and dried by vacuum freeze-drying technology to form compound germinated brown rice convenient rice.

Benefits of technology

It improves the taste and viscoelasticity of the rice with germinated brown rice, shortens the rehydration time, reduces the waist-burning rate, and reduces nutrient loss and wastewater discharge, improving the nutritional value and storage time of the product.

Abstract

The invention relates to the technical field of deep processing of rice, in particular to instant rice compounded with germinated brown rice and a preparation method thereof.The preparation method comprises the steps that pretreatment is conducted, specifically, high-quality brown rice is selected, brown rice which is full in grain and free of mildew and decay is selected and washed, and dust impurities on the surfaces of raw materials are washed away with clear water; the treated brown rice is placed in a germination machine, spraying humidification and germination are conducted for corresponding time through a micro spraying humidification technology, germinated brown rice with the corresponding bud length is obtained, steam pre-gelatinization is conducted, the germinated brown rice is placed in a reaction kettle of a steam generator, pre-gelatinization treatment is conducted on the germinated brown rice through steam, and the pre-gelatinized brown rice with the corresponding bud length is obtained. According to the compound germinated brown rice instant rice and the preparation method thereof disclosed by the invention, the germinated brown rice is compounded with the germ-remaining polished rice, so that reasonable matching of coarse grains and fine grains is realized, nutrient substances of the compound germinated brown rice instant rice are enriched, and meanwhile, the taste and viscoelasticity of the compound germinated brown rice instant rice are improved.
