Embodiment 1

[0038] A preparation method of germinated brown rice, comprising the steps of:

[0039] 1) Cleaning: put brown rice in an ultrasonic cleaning machine equipped with 0.3% sodium bicarbonate solution at room temperature, power 300W, frequency 35KHz ultrasonic cleaning for 10min, rinse and drain;

[0040] 2) Pre-soaking: Soak the washed brown rice in water for 5 hours at a temperature of 13°C, ventilate once every 35 minutes, and ventilate at a pressure of 0.12MPa. until the moisture content of brown rice is 36%;

[0041] 3) Pre-germination: Drain the soaked brown rice and carry out dark germination in the germination chamber. The dark germination temperature is kept at 22°C, and the dark germination time is 11 hours. During this period, water is sprayed until the moisture content of the brown rice reaches 41%;

[0042] 4) Re-soaking: soak the pre-germinated brown rice in water at a temperature of 40°C for 18 minutes to kill the germ until the moisture content of the brown rice r...

Embodiment 2

[0047] A preparation method of germinated brown rice, comprising the steps of:

[0048] 1) Cleaning: put brown rice in an ultrasonic cleaning machine equipped with 0.2% sodium bicarbonate solution at room temperature, power 200W, frequency 30KHz ultrasonic cleaning for 5min, rinse and drain;

[0049] 2) Pre-soaking: soak the washed brown rice in water for 4 hours at a temperature of 12°C, ventilate once every 30 minutes, and ventilate at a pressure of 0.10 MPa. until the moisture content of brown rice is 35%;

[0050] 3) Pre-germination: Drain the soaked brown rice and carry out dark germination in the germination room. The dark germination temperature is kept at 20°C, and the dark germination time is 10 hours. During this period, water is sprayed until the moisture content of the brown rice reaches 40%;

[0051] 4) Re-soaking: soak the pre-germinated brown rice in water at a temperature of 38°C for 15 minutes to kill the germ until the moisture content of the brown rice reac...

Embodiment 3

[0056] A preparation method of germinated brown rice, comprising the steps of:

[0057] 1) Cleaning: put brown rice in an ultrasonic cleaning machine equipped with 0.4% sodium bicarbonate solution at room temperature, power 400W, frequency 40KHz ultrasonic cleaning for 15min, rinse and drain;

[0058] 2) Pre-soaking: Soak the washed brown rice in water for 6 hours at a temperature of 15°C, ventilate once every 40 minutes, and ventilate at a pressure of 0.13MPa. until the moisture content of brown rice is 38%;

[0059] 3) Pre-germination: Drain the soaked brown rice and carry out dark germination in the germination room. The dark germination temperature is kept at 24°C, and the dark germination time is 12 hours. During this period, water is sprayed until the moisture content of the brown rice reaches 42%;

[0060] 4) Re-soaking: soak the pre-germinated brown rice in water at a temperature of 42°C for 20 minutes to kill the germ until the moisture content of the brown rice reache...

Abstract

The invention discloses sprouted whole grain with a long quality guarantee period and a preparation method of the sprouted whole grain, and belongs to the technical field of deep processing of grain. Ultrasonic cleaning is performed on a soaking process, a high voltage pulse electric field, biological enzymolysis or combination of the high voltage pulse electric field and the biological enzymolysis is performed, a sectional soaking and sprouting manner is adopted for sprouting, so that the sensory quality, the sprouting yield and the sprouting quality of a sprouted whole grain product are improved, and the sprouting loss is reduced. The preparation method disclosed by the invention is simple, soaking temperature and sprouting temperature are low, soaking period and sprouting period are short, energy resources are saved, the preparation method is environmentally friendly; contents and food safety of functional substances, nutritional substances and biological activity substances in the sprouted whole grain product are observably increased and improved; brown rice is taken as an example, the content of gamma-aminobutyric acid of sprouted brown rice prepared by the preparation method disclosed by the invention is 303.8-312.6mg / 100g, the content of glutathione is 16.8-18.3mg / 100g, the content of Inositol Hexaphosphate(IP6) is 460.8-484.4mg / 100g, and the content of dietary fibers is 3.5-3.6mg / 100g.

Description

technical field [0001] The invention belongs to the technical field of grain deep processing, and in particular relates to a germinated whole grain with a long shelf life and a preparation method thereof. Background technique [0002] Whole grain refers to the complete natural seed that only removes the outer husk of the seed during the processing of the grain grain, that is, the protective cortex that is not conducive to eating, and preserves all natural nutrition and precision processing, such as the new generation of rice-don't wash rice. It is different from the refined grains that have to use up all the cortex and germ in the current over-processing. Whole grains include four parts: aleurone layer, sub-aleurone layer, germ and endosperm. Each layer has irreplaceable organic nutrients, and more Nutritious, healthier. The cortex is the rough outer layer of the grain, which contains a large amount of cellulose, and more than 50% of the minerals of the seeds are contained ...
