Effect of Modified Atmosphere Package with Different Gas Components on Egg Preservation

Abstract

Abstract: In order to extend the storage period of eggs, the effect of modified atmosphere package (MAP) with different gas components on egg preservation at room temperature (25 ℃) was explored. The results showed that when eggs were stored in MAP with the gas compositions of 50% CO2, 7%－11% O2 and 39%－43% N2, the weight loss rate and albumen pH of eggs remained at a relatively low level, and haugh unit and albumen gel-strength were kept at a relatively high level. The eggs stored in MAP were AA degree, whereas the control group without MAP were B degree after 30 days storage. This study provides theoretical and technological basis for egg fresh-keeping strategy and storage.

Key words: egg, modified atmosphere packaging (MAP), storage temperature, weight loss rate, haugh unit
