Abstract

The present invention discloses a method for processing anti-retrogradation instant cooked rice using indica rice. The indica rice is used as a raw material, and the method comprises the steps of screening and impurity removing, soaking and microwave pretreating, superheated steam pre-gelatinizing and shaping, vacuum quantitative packaging, back pressure microwave curing and instant cooked rice obtaining. The method aims at problems that the instant cooked indica rice is serious in retrogradation, poor in mouthfeel, more in broken grains, not easy for digestion, etc., uses a compound retrogradation inhibiting agent to soak the indica rice, combines the microwave pretreating and back-pressure microwave curing ripening, and effectively inhibits the retrogradation. The superheated steam fluidized state treatment is used, so that surface starch of the indica rice grains is pre-gelatinized and then an air-cooling achieves a shaping. The vacuum packaging and back pressure microwave curing are combined to prevent the rice grains from being over-expanded. The product is good in flavor, excellent in mouthfeel, advanced and reasonable in processing technology, good in quality and broad in prospects.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a method for processing anti-regrowth instant rice by using indica rice. Background technique [0002] Rice is steamed from rice with a certain moisture content, and more than two-thirds of the population in China mainly uses rice as a staple food. With the rapid development of China's social economy and the accelerated pace of people's life, there is an increasing demand for instant rice that does not require rehydration and is convenient to eat. But instant rice is easy to regenerate, which not only affects the taste, but also is not conducive to digestion. Indica rice is the rice variety with the highest yield and the widest planting range in my country, accounting for more than 70% of the national rice production. Indica rice has a high amylose content and a lower viscosity than glutinous rice and japonica rice. It is precisely because of the high amylos...
