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.%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.
