Abstract

The invention provides instant germinated brown rice and a preparation method thereof. The preparation method comprises the following steps: Step a, treating the germinated brown rice by utilizing a biological enzyme method, so that enzyme-treated germinated brown rice is prepared; Step b, carrying out negative-pressure freezing treatment on the enzyme-treated germinated brown rice, so that freeze-treated germinated brown rice is prepared; Step c, curing the freeze-treated germinated brown rice, so that cured germinated brown rice is prepared; and Step d, carrying out microwave low-temperature hot-air drying on the cured germinated brown rice, so that the instant germinated brown rice is prepared. The preparation method is capable of greatly shortening rehydration time and improving rehydration rate of the instant germinated brown rice; thus, the product qualities are improved, and the preparation method is suitable for industrialized production.

Description

technical field [0001] The present invention relates to a kind of preparation method of instant rice, more specifically, relate to a kind of germinated brown rice instant rice and preparation method thereof. Background technique [0002] As the pace of life is getting faster and faster, instant food is deeply loved by office workers and travelers. However, the unbalanced nutrition mix seriously affects the health of "fast food family". [0003] Germinated brown rice refers to the bud body of brown rice that has been germinated to a suitable bud length, and is mainly composed of young buds and endosperm with cortex. The nutritional value of germinated brown rice is very rich, rich in Gama-aminobutyric acid and other nutritional components, the nutritional value is much higher than that of polished white rice, and it has certain functional curative effects. [0004] And the product in current market is mainly with ungerminated brown rice as raw material, and brown rice can p...
