普通鸡蛋、土鸡蛋和乌鸡蛋的蛋品质比较研究

Comparative Study on the Egg Qualities of Ordinary Eggs,Native Eggs and Dark Eggs

为比较人们日常消费中不同种鸡蛋的蛋品质状况,试验以天津市某大型超市中出售的3种鸡蛋(普通鸡蛋、土鸡蛋和乌鸡蛋)为研究对象,对其蛋品质进行检测分析。结果表明:普通鸡蛋的蛋重、蛋清重和蛋壳重均显著高于土鸡蛋(P<0.05),土鸡蛋的蛋黄重显著低于普通鸡蛋及乌鸡蛋(P<0.05),乌鸡蛋的蛋黄比率和蛋黄颜色显著高于普通鸡蛋及土鸡蛋(P<0.05),普通鸡蛋和土鸡蛋的蛋清比率均显著高于乌鸡蛋(P<0.05),土鸡蛋的哈氏单位显著高于普通鸡蛋和乌鸡蛋(P<0.05),乌鸡蛋的蛋壳比率和蛋壳强度显著低于普通鸡蛋和土鸡蛋(P<0.05),普通鸡蛋的蛋壳厚度显著高于土鸡蛋和乌鸡蛋(P<0.05)。试验结果可为不同人群进行鸡蛋消费选择提供理论实践指导。

In order to compare the egg qualities of ordinary eggs, native eggs and dark eggs, the experiment was conducted to study the quality of three kinds of eggs sold from a large supermarket in Tianjin city. The results showed that the egg weight, egg white weight and egg shell weight of ordinary eggs were significantly higher than that of native eggs（P〈0.05）.Egg yolk weight of native eggs was significantly lower than that of the other two （P〈0.05）, the ratio of egg yolk and egg yolk color of dark eggs were significantly higher than that of the others （P〈0.05）. Egg protein ratio of ordinary eggs and native eggs was significantly higher than that of dark eggs （P〈0.05）, the HA units of native chicken eggs were significantly higher than that of ordinary eggs and black eggs （P〈0.05）, the ratio of eggshell and eggshell strength of dark eggs were significantly lower than that of the other two （P〈0.05）, the eggshell thickness of ordinary eggs was significantly higher than that of native eggs and dark eggs （P〈0.05）. These results can provide a theoretical reference for the selection of eggs for different groups of people.
