Preparation method for producing germinated glutinous brown rice flour with low glycemic index by microwave combined heat-moisture treatment

[0025] Example 1: A preparation method for producing germinated glutinous brown rice flour with low glycemic index by microwave combined with heat and humidity treatment

[0026] Wash the glutinous brown rice and germinate it in an automatic hypoxic stress germination machine for 16 hours. The temperature is controlled at 35°C and the dissolved oxygen concentration is maintained at 3 mg / L. After the germinated glutinous brown rice is simply washed, the amount of water added is controlled between 1:1, and then it is crushed by wet method. The pulverized germinated glutinous brown rice slurry was treated at 55°C for 60 seconds under the condition of microwave power 200W, thereby increasing the activity of endogenous proteases, followed by incubation for 80 minutes, and the stirring speed of the enzymatic conditioning reaction was 20rpm; the processed rice slurry The plate and frame filter press is used to squeeze the water, and the moisture content is controlled to 25% after hot

[0028] Wash the glutinous brown rice and germinate it in an automatic hypoxic stress germination machine for 20 hours. The temperature is controlled at 40°C and the dissolved oxygen concentration is maintained at 5 mg / L. After the germinated glutinous brown rice is simply cleaned, the amount of water added is controlled between 1:1.5, and then it is crushed by wet method. The pulverized germinated glutinous brown rice slurry was treated at 50°C and microwave power 400W for 40 seconds to increase the activity of endogenous proteases, and then incubated for 60 minutes. The stirring speed of the enzymatic conditioning reaction was 80rpm; the processed rice slurry The plate and frame filter press is used to squeeze the water, and the moisture content is controlled to 20% after hot air drying, and then the wet hea

[0029] Example 3: A preparation method for producing germinated glutinous brown rice flour with low glycemic index by microwave combined with heat and humidity treatment

[0030] Wash the glutinous brown rice and germinate it in an automatic hypoxic stress germination machine for 18 hours. The temperature is controlled at 38°C and the dissolved oxygen concentration is maintained at 6 mg / L. After the germinated glutinous brown rice is simply cleaned, the amount of water added is controlled between 1:2, and then it is crushed by wet method. The pulverized germinated glutinous brown rice slurry was treated at 40°C for 20 seconds under the condition of microwave power 600W to increase the activity of endogenous proteases, followed by incubation for 40 minutes, and the stirring speed of the enzymatic conditioning reaction was 60rpm; Use a plate-and-frame filter press to squeeze water, and after drying with hot air, control the moisture content to 15%. Then, the temperature of the we
