赤水乌骨鸡绿壳蛋颜色测定分析

Determination and Analysis of Green Shell Egg Color of Chishui Black Bone Chicken

[目的]探究赤水乌骨鸡绿壳蛋的蛋壳颜色规律。[方法]以赤水乌骨鸡所产的绿壳蛋为研究对象,利用NR型蛋壳颜色色差计测定300日龄时深绿色、中绿色、浅绿色各100枚绿壳蛋的蛋壳颜色数值,并从各组中选取30枚鸡蛋进行蛋品质检测。[结果]深绿色组△L在44.90~52.57,中绿色组△L在53.07~56.99,浅绿色组△L在57.02~61.37;蛋壳厚度深绿组极显著高于中绿组和浅绿组(P<0.01),蛋白高度和哈氏单位均是深绿组显著高于中绿组和浅绿组(P<0.05)。蛋壳颜色△L在45~53为深绿色,>53~57为中绿色,>57为浅绿色,且深绿组蛋品质高于中绿组和浅绿组,中绿组蛋品质高于浅绿组。[结论]该研究为赤水乌骨鸡所产绿壳蛋蛋壳颜色深浅的市场定价和其他绿壳蛋提供参考依据。

[Objective]To explore the eggshell color rule of Chishui black bone chicken eggshell.[Method]Green shell eggs of Chishui black bone chickens were used as the research object.The shell color values of 100 dark green,medium green and light green eggs were measured by USING NR type shell color difference meter at 300 days of age,and 30 eggs were selected from each group for egg quality detection.[Result]△L of dark green group was 44.90-52.57,△L of medium green group was 53.07-56.99,△L of light green group was 57.02-61.37.Eggshell thickness in dark green group was significantly higher than that in medium green group and light green group(P<0.01),protein height and Haugh unit in dark green group were significantly higher than that in medium green group and light green group(P<0.05).The egg shell color△L 45-53 was divided into dark green,>53-57 into medium green,>57 into light green.The egg quality of dark green group was higher than that of medium green group and light green group,and the egg quality of medium green group was higher than that of light green group.[Conclusion]The study provides reference for the market pricing and other green shell eggs of Chishui black bone chicken eggshell color.
