Abstract

The invention discloses a microwave sterilization and preservation prolonging method for rice noodles. The method comprises the steps of loading, primary microwave sterilization, secondary microwave sterilization, third microwave sterilization, cooling sterilization, rice noodle packaging and the like, after the rice noodles are loaded, the rice noodles are sequentially subjected to three times of microwave sterilization with different frequencies and different time, after cooling, the rice noodles are subjected to vacuum packaging in an ultraviolet irradiation environment, and the sterilized and packaged river snail rice noodles are obtained. The process is simple and effective, bacteria on the river snail rice noodles can be killed, the preservation time of the rice noodles is prolonged, and storage and transportation are facilitated.

Description

technical field [0001] The invention belongs to the technical field of production and processing of snail noodles, and in particular relates to a method for microwave sterilization of rice noodles and extended warranty. Background technique [0002] Snail powder is a famous snack in Guangxi. It tastes sour, refreshing and spicy, and is widely loved by people. In recent years, the Liuzhou snail noodle industry has accelerated its development. In 2020, the handmade techniques of Liuzhou snail noodle will be included in the list of national intangible cultural heritage. The vermicelli of snail noodles are made of aged de-oiled rice, coupled with a unique production and processing technology, which makes the vermicelli soft, tough, refreshing and full of elasticity. In order to promote snail noodles more favorably, manufacturers currently pre-package snail noodles and ingredients to achieve long-term and long-distance transportation. However, due to the influence of various fu...
