Problems solved by technology

This shortage of supply is mainly due to the fact that chilled meat cannot completely inhibit the growth and reproduction of certain psychrophilic bacteria such as Staphylococcus aureus and coliform bacteria during storage, transportation and sales, and the browning of the surface of chilled meat and the loss of juice Serious, short shelf life, not conducive to long-distance transportation

Abstract

The invention relates to a fresh-keeping film for chilled meat and its preparation and application method. The fresh-keeping film is made of raw materials comprising the following components in parts by weight: 30-50 parts of food-grade polyvinyl alcohol, 45-70 parts of glutinous rice flour, and 2-10 parts of glycerin. The fresh-keeping film can not only prolong the shelf life of chilled meat, but also predict the shelf life of chilled meat. The fresh-keeping film of the present invention is used for storing chilled pork, and the shelf life can reach 18 days, beef can reach 20 days, mutton can reach 19 days, chicken can reach 15 days, and duck meat can reach 14 days.

Description

technical field [0001] The invention belongs to the field of livestock and poultry meat processing and utilization, and in particular relates to a fresh-keeping film for chilled meat and a preparation and use method thereof. Background technique [0002] Chilled meat refers to the animal carcass that meets the requirements of the quarantine system and is quickly cooled and matured after slaughter, so that the temperature of the carcass (the inside of the rear leg is the measurement point) is reduced to 0-4°C within 24 hours, and it is processed in the subsequent processing, circulation and Fresh meat kept at 0-4°C during the retail process. At present, more than 90% of the consumption in the foreign fresh meat market is chilled meat. The consumption level of meat in our country is not only limited by the income level, but also limited by the supply. With the reform and opening up, my country's economy has developed rapidly, and people's living standards have continued to i...
