Ozone sterilization egg fresh-keeping process

Abstract

The invention discloses a method for sterilizing and preserving eggs by ozone, which comprises the steps that: on the conditions of normal temperature of 20 DEG C plus or minus 2 DEG C and normal pressure, which is standard atmospheric pressure, eggs which are laid 1 to 7 days ago are immersed in an ozone water solution with a concentration of 6mg / L, then the eggs are taken out 10 minutes later and then naturally dried with air; then the processed eggs can be preserved for 30 days without going bad by being stored in the environment with the temperature of 20 DEG C plus or minus 2 DEG C and the relative humidity of 70 percent. The invention has a good application prospect in eggs preservation.

Description

A kind of ozone sterilized egg preservation method Technical field: The invention relates to a food preservation method, in particular to an ozone sterilized egg preservation method. Background technique: In the past two decades, my country's poultry and egg production has been ranking first in the world. In 2005, it reached 28.674 million tons (more than 80% of which were eggs), and the per capita reached 20.42 kilograms, exceeding the world average level. The quality and safety of eggs has an important impact on the health of consumers and the economic interests of the country. How to prolong the shelf life of fresh eggs and improve the safety of eggs is an urgent problem to be solved at present. Studies have shown that about 10% of fresh eggs contain pathogenic bacteria, mold or parasite eggs. The microorganisms often found in eggs are mainly bacteria and molds, and most of them are aerobic but also anaerobic. The bacteria found in eggs mainly include Staphylococcus...
