Abstract

The invention relates to a storing and processing method of rice and belongs to the technical field of crop processing. The process disclosed by the invention comprises the following steps: feeding into a warehouse: feeding wet rice into the warehouse; removing water: controlling the water content of the rice to 15-16% in a manner of warehouse ventilation; storing at low temperature: reducing the temperature of the warehouse to 18-25 DEG C to carry out low-temperature storage; and carrying out low-temperature and high-humidity processing. According to the process disclosed by the invention, the water content and the temperature of processing and storing the rice are controlled and the low-temperature and high-humidity processing is carried out at the water content and the temperature, so that the oxidation degree of fatty acid is low and the water absorbing speed in a process of immersing the rice to make rice is low; and the rice has the characteristics of small cracks in the water, good elasticity, good appearance and high freshness, and the rice has good edible quality, good mouth feel and good taste.

Description

technical field [0001] The invention relates to a method for storing and processing food crops, more specifically, the invention relates to a method for storing and processing rice, which belongs to the technical field of crop processing. Background technique [0002] After the rice is harvested, the general processing method is drying in the sun or mechanical drying, and then storing and processing for packaging and sales. [0003] Drying is often affected by high temperature, rainy weather and uncertain external pollutants during the harvest season, which can easily lead to rice germination, mildew, increase in yellow-grained rice, sanitary pollution, quantity loss, and quality decline. The cost of mechanical drying is high, the one-time investment is large, and the drying time is long. After drying to safe storage of water, the fatty acid value increases significantly, the germination potential and germination rate decrease, and the rice yield decreases. The rice cooked b...
