鹌鹑蛋新鲜度随贮藏时间变化规律的研究

Analysis on Dynamics Changes of the Quail Egg Fresh Index According to the Storage Time

通过对不同贮藏时间的鹌鹑蛋品质的测定,研究了鹌鹑蛋新鲜度随贮藏时间的变化规律。结果显示,蛋黄指数、哈氏单位、比重均与贮藏时间之间呈极显著负相关(P<0.01),失重率与贮藏时间之间呈极显著正相关(P<0.01),蛋壳强度与贮藏时间无显著相关(P>0.05)。用直线模型可以较好地描述蛋黄指数、失重率和比重随贮藏时间变化的规律,而多项式模型则可以较好地描述哈氏单位随贮藏时间变化的规律。

The effects of storage time on eggs quality of yellow feather quail breeds were measured to study dynamics changes of the quail egg fresh index according to the storage time.The results showed that there were an obvious negative correlation between the storage time and the other indexes including egg yolk index,haugh unit,and specific gravity（P0.01）,and a significant positive correlation between the weight loss rate and storage time（P0.01）,but no correlation between shell strength and storage time（P0.05）.Furthermore,linear model could accurately predict the change of egg yolk index,specific gravity and weight loss rate according to different storage time;while polynomial model could be used to accurately predict the change of egg haugh unit as storage time changes.
