摘　　要：以缙云麻鸭所产鸭蛋为素材,采用ECR测色仪对其4种类型鸭蛋的蛋壳颜色进行定量测定,每种类型测50个蛋,每个蛋测定3个点.结果表明：白壳、浅青壳、青壳和深青壳4组蛋的反射系数均值各组间差异极显著（P〈0.01）;利用反射系数与蛋壳颜色的回归分析得出划分青壳蛋颜色层次的量化区间,即白壳蛋80.64~84.42,浅青壳蛋77.74~80.64,青壳蛋74.85~77.74,深青壳蛋64.69~74.95;对各测定点的测定值与均值的相关分析和主成分分析表明,中端为蛋壳颜色的最佳测定点,其准确性可达到0.8934;蛋壳反射系数与时间的回归分析表明,不同时间的反射系数测定值间差异不显著（P〉0.05）.ECR reflectometer was used for quantitative determination of four colors in Jinyun duck-eggshells.Fifty eggs with three points were measured for every color.Results showed that there existed extremely significant differences（P0.01） in the average values of the reflection coefficient among four group eggshells,and the quantized interval of color reflectance was 80.64-84.42,77.74-80.64,74.85-77.74 and 64.69-74.95 in white,light blue,blue and deep blue eggshells,respectively.Statistic analysis indicated that the middle of the eggshell was the best measurement point of eggshell color,which accuracy reached 0.8394.The regression analysis showed that there was no significant differences（P0.05） between the reflection coefficient of the eggshells and different measurement time.
