臭氧杀菌真空包装保鲜珍禽蛋研究

Research on the Fresh Preservation of Rare Birds Eggs Using Ozone Sterilization and Vacuum Packing

采用臭氧杀菌真空包装的方法进行乌鸡蛋的保鲜,综合鸡蛋减重率、蛋白指数、蛋黄指数和蛋黄pH值四项指数进行分析和研究,确定采用此工艺的最佳工艺流程和参数:过氧乙酸溶液预杀菌浓度为0 5%,臭氧杀菌3min,选用Ny/PE复合袋在真空度600mmHg下进行真空包装,保鲜期为7个月,好蛋率95%以上。

The paper introduces the method for preserving the fresh rare birds eggs using ozone sterilization and vacuum packing,and describes the optimum technological process and parameters after a comprehensive analysis and study of the egg's weight-reduced rate,egg white index,and yolk index and it's pH value,i.e.the pre-sterilizing concentration of peroxyacetic acid is 05%.The sterilizing process should be carried out for 3 min,and then the eggs are preserved in Ny/PE compound bags under vacuum condition (600 mmHg).The experiment result shows that 95% of eggs are well kept after 7 months' preservation.
