A method for keeping fresh cut meat of Chinese giant salamander with ternary mixed atmosphere

Abstract

The invention discloses a preservative method of andrias davidianus chilled fresh cut meat through ternary-mixed modified atmosphere. The method includes following steps: 1) performing after treatment of the steps of washing andrias davidianus and the like, cutting meat, claw and ribs into pieces being 1-10 cm in size, and soaking the cut meat into a sterilizing and disinfecting agent being 5-70 mg / l in concentration for 2-30 min; 2) treating the cut meat at -5 - 12 DEG C for 5-40 min; 3) packaging the treated andrias davidianus cut meat into plastic boxes and bags with water-absorbing and anti-bacterial paper placed under the meat; 4) performing gas-filled packaging with the gas including 5-50% of O2, 10-90% of CO2 and 50-70% of N2, wherein the mass ratio of filling amount to the meat is 0.2:1-10:1 (V / W); and 5) storing and transporting the packaged andrias davidianus cut meat at 0-4 DEG C. A test result proves that the smell, color and appearance of the andrias davidianus cut meat after preservation for 20 days does not changed obviously, wherein the total microbial count is lower than 5*10<5> cfu / g.

Description

technical field [0001] The invention relates to the technical field of processing aquatic products and meat products, in particular to a method for preserving freshness by adopting ternary mixed air-conditioned giant salamander chilled freshly cut meat. Background technique [0002] The giant salamander is the largest and most precious amphibian in the world. The giant salamander (Megalobatrachus davidianus) is a rare and large amphibian unique to my country and is a national second-class protected animal. It is a key development variety for agricultural industrialization and characteristic agriculture, and a genetically protected species of wild animals. Except for Tibet, Inner Mongolia, and Taiwan, which have not been reported, the Chinese giant salamander is distributed in other provinces and regions. It is mainly produced in the mountains and streams of the Yangtze River, the Yellow River and the upper and middle tributaries of the Pearl River. Giant salamander meat is...
