摘　　要：本试验对果园放养的绿壳蛋鸡蛋品质及安全评价进行了检测分析。结果表明:绿壳蛋含水量为85.16%,低于放养土鸡和笼养鸡所产蛋;蛋白、蛋黄比率达31.53%以上;所测的总氨基酸中,蛋清为12.541g/100g,蛋黄为14.256g/100g,必需氨基酸蛋清为5.361g/100g,蛋黄为5.947g/100g;蛋清、蛋黄中锌含量分别为0.51mg/100g、18.503mg/100g,硒含量分别为0.55mg/100g、3.06mg/100g,高于放养土鸡和笼养鸡所产蛋;安全指标中,除镉和氟检测有实际数值外,其它均未检出,微生物指标检测的数值也相对较低。The quality and safety of green-shell eggs from flee-range chickens reared in orchard were analyzed and evaluated. The results showed that water content of green-shell eggs was 85.16% ,lower than that of eggs from free-range local chickens and eaged chickens;ratio of egg white to egg yolk was more than 31.53%;total amino acids of egg white detected was 12.541 g/100 g and that of egg yolk was 14.256 g/100 g;essential amino acids of egg white was 5.361 g/100 g,and that of egg yolk was 5.947 g/100 g;zine eontents of egg white and egg yolk were 0.51 rag/100 g and 18.503 mg/100 g, respectively, selenium content of those were 0.55 mg/100 g and 3.06 mg/100 g, respectively, slightly higher than those of eggs from free-range local chickens and caged chickens. Except for cadmium and fluorine, the other safety indicators had no actual value, according to existing detection methods, and microbial detection value was also relatively low.
