摘要
为了研究枣庄市售不同鸡蛋的蛋品质及营养成分差异,对市售不同鸡蛋的外观、营养指标、微量元素等进行对比,采用单因素方差分析和多重比较方法对所得理化试验数据进行分析.结果表明:富硒鸡蛋、绿色生态鸡蛋表现出外观品质好、蛋腥味轻、蛋黄颜色深(P<0.05)、浓蛋白黏稠与稀蛋白界限清晰可辨、哈氏单位高(P<0.05)等特点;四种鸡蛋样品中普通鸡蛋甘油三酯、胆固醇含量最高,其次是土鸡蛋,然后是生态鸡蛋,富硒鸡蛋胆固醇含量最低;富硒鸡蛋卵磷脂含量最高,其次是生态鸡蛋、土鸡蛋,普通鸡蛋卵磷脂含量最低;富硒鸡蛋硒含量明显高于其他鸡蛋(P<0.05),但是土鸡蛋中钙含量显著高于其他鸡蛋(P<0.05);富硒鸡蛋、生态鸡蛋铅含量更低.
Abstract
In order to study the differences in egg quality and nutritional components among different egg sold in Zaozhuang,the appearance,nutritional indicators,trace elements of different egg were compared,and the physicochemical results were analyzed by one-way ANOVA and multiple comparison methods.The results showed that in terms of egg quality,selenium rich egg and green ecological egg exhibited good appearance quality,light fishy taste,deep yolk color(P<0.05),clear and dis-tinguishable boundary between thick and thin protein,and high Haugh Unit(P<0.05).Among the four types of egg sam-ples,ordinary egg have the highest triglycerides and cholesterol content,followed by native egg,then followed by ecological egg,and selenium rich egg have the lowest triglycerides and cholesterol content.While the content of lecithin in selenium rich egg is the highest,successively followed by ecological egg and native egg,and finally ordinary egg have the lowest content of lecithin.In addition,in terms of trace element content,selenium rich egg have significantly higher selenium content than other egg(P<0.05),while the calcium content in soil egg is significantly higher than other groups(P<0.05).In terms of lead content in egg,selenium rich egg and ecological egg have lower lead content.
