Method used for improving local flavor and mouthfeel of rice cooked at high temperature under high pressure

Abstract

The invention discloses a method used for improving the local flavor and mouthfeel of rice cooked at high temperature under high pressure, and belongs to the technical field of instant food processing. The method comprises following steps: fresh rice is subjected to rinsing, is immersed in hot water of 96 DEG C for 10 to 15min until the rice is half cooked, and the half-cooked rice is taken out from water; rice vinegar, peanut oil, and trehalose are added into the half-cooked rice for uniform mixing, wherein the mass amount of rice vinegar accounts for 1 to 2% of that of rice, the mass amountof peanut oil accounts for 1 to 2% of that of rice, and the mass amount of trehalose accounts for 0.5 to 1% of that of rice, an obtained mixture is subjected to nitrogen-filled packing; two stage hightemperature high pressure sterilization is adopted, cold chain storage / transportation is adopted, and rice retrogradation evaluation and texture measuring are carried out. According to the method, rice steam cooking process is avoided, rice vinegar and trehalose are added, nitrogen-filled packaging is adopted, so that the retrogradation phenomenon of rice in cold chain storage / transportation process is controlled effectively. The obtained rice product can be eaten after treatment for 4 to 5min in a baking oven at 250 DEG C or 2 to 3min in a microwave oven with strong fire; more than 90% elasticity, more than 95% viscosity, and appropriate softness and hardness are maintained after 9 months of storage, and retrogradation phenomenon is not detected by sense organs.

Description

Technical field [0001] A method for improving the flavor and taste of rice after high temperature and high pressure belongs to the technical field of convenient food processing. Background technique [0002] Rice is the main food of our country, especially the people of the South. With the changes in market demand, people are demanding more and more convenience food in order to reduce the pressure on the kitchen, and instant rice is gradually being developed. At present, there are not many such products on the market. After the boxed rice is sterilized by high temperature and high pressure, the flavor of the rice is compared with that of the cooked rice, and there is no fragrance and soft texture of the cooked rice. More research is needed. Therefore, the research on the processing technology of instant rice and its quality control technology can make the taste and aroma of instant rice closer to that of freshly cooked rice, and further satisfy consumers' needs for convenient, h...
