次氯酸钠杀菌结合聚乙烯醇基纳米SiO2复合材料涂膜对鸭蛋保鲜效果的影响
Effect of sodium hypochlorite disinfection combined with polyvinyl alcohol-based composite packaging material with nano-SiO2 coating on fresh-keeping of duck eggs
摘要
Abstract
To evaluate the effect of sodium hypochlorite disinfection combined with polyvinyl alcohol-based composite packaging material with nano-SiO2 coating on fresh-keeping of duck eggs,the fresh eggs were treated by sodium hypochlorite disinfection,polyvinyl alcohol-based composite packaging material with nano-SiO2 coating,and sodium hypochlorite disinfection combined with polyvinyl alcohol-based composite packaging material with nano-SiO2 coating.All the duck eggs were stored at the same condition for 35 days and the changes of weight loss rate,total plate count,Hough units and yolk index value of duck eggs in each group were detected during storage process.The changes of the eggshell color and texture properties of duck eggs by three fresh-keeping treatments were also detected after storage.The results revealed that the weight loss rate and total plate count of duck eggs in three fresh-keeping groups were significantly decreased in comparison with control group (p ＜ 0.05),and the disinfection combined with coating showed the lowest weight loss rate (2.79％ ± 0.19％)and total plate count(4.83 ± 0.42) lg cfu/g.The Hough units and yolk index value of duck eggs in three fresh-keeping groups were significantly increased in comparison with control group (p ＜ 0.05),and the disinfection combined with coating showed the highest Hough units(76.09± 4.15)and yolk index value (0.40 ± 0.02),with no obvious difference to the fresh eggs before storage.In addition,the texture properties of eggs treated by disinfection combined with coating showed no significant difference relative to control group (p ＞ 0.05),but the brightness was notably improved (p ＜ 0.05).In conclusion,the three fresh-keeping treatments were significantly reversed the decline of the quality of duck eggs in comparison with control group(p ＜ 0.05).To be mentioned,sodium hypochlorite disinfection combined with polyvinyl alcohol-based composite packaging material with nanoSiO2 coating exhibited the best fresh-keeping effect,which was significantly better than treated by sodium hypochlorite disinfection and polyvinyl alcohol-based composite packaging material with nano-SiO2 coating alone (p ＜ 0.05).This study might provide reference for the application of disinfection combined with composite packaging material coating in the preservation of fresh eggs.关键词
