| 摘 要： | 本试验旨在研究涂膜保鲜剂对蛋壳薄斑及蛋品质的影响。选择同日产无薄斑海兰褐鸡蛋185个分为对照组、液体石蜡组和聚乙烯醇组,每组60个,储藏22d,每5d左右观察一次薄斑的生成情况,并抽取薄斑蛋测定蛋品质情况。结果显示,随储藏时间的延长,各试验组鸡蛋薄斑比例有上升趋势,蛋品质有下降趋势。储藏5d后,对照组失重率显著高于(P<0.05)液体石蜡组和聚乙烯醇组,聚乙烯醇组哈夫单位显著(P<0.05)高于液体石蜡组。储藏22d后,3个试验组的失重率均存在显著差异(P<0.05);对照组的蛋白高度、哈夫单位、分级评分均显著低于(P<0.05)液体石蜡组和聚乙烯醇组,而聚乙烯醇组与液体石蜡组差异不显著(P<0.05)。另外,薄斑蛋比例与蛋白高度及哈夫单位均存在极显著的相关性(P<0.01)。结果表明,两种涂膜保鲜剂对抑制薄斑生成、保持鸡蛋品质具有明显作用。

| Abstract: | The main objective of this study was to investigate the effects of different agents on thin spots and egg quality.One hundred and eighty five Hy-Line Brown eggs produced in the same day with no thin spots were collected and five eggs were detected for basic data,the others were divided into control group,liquid paraffin group and polyvinylalcohol(PVA) group,with sixty per group.In each group during twenty days' storage,the thin spots eggs and egg quality were detected in each five days.The results showed th... |
