摘要: 贮期鸡蛋品质的变化与呼吸作用息息相关,为了更进一步明确鸡蛋内部品质与其呼吸强度之间的关系,本试验选取同一品种的鸡蛋作为试验样本,利用呼吸测定仪测量鸡蛋的二氧化碳呼吸强度,通过SPSS 19.0软件分别分析鸡蛋哈夫单位、蛋白高度、pH、黏度、蛋黄指数、蛋黄比例以及蛋黄颜色对鸡蛋呼吸强度的影响。结果表明:鸡蛋哈夫单位、蛋白高度及黏度与呼吸强度之间极显著正相关(R = 0.763,P < 0.01;R = 0.826,P < 0.01;R = 0.840,P < 0.01);pH与呼吸强度之间极显著负相关(R = -0.814,P < 0.01);蛋黄指数、蛋黄颜色与呼吸强度之间极显著正相关(R = 0.634,P < 0.01;R = 0.878,P < 0.01);而蛋黄比例与呼吸强度间相关性较小;此外,pH与黏度、蛋黄指数、蛋黄颜色均存在极显著负相关关系(R = -0.990,P < 0.01;R = -0.922,P < 0.01;R = -0.963,P < 0.01);黏度与蛋黄指数、蛋黄颜色之间极显著正相关(R =0.904,P < 0.01;R = 0.968,P < 0.01);蛋黄比例与其他相关参数相关性较小。总之,在鸡蛋内部品质参数中,鸡蛋哈夫单位、蛋白高度、蛋黄指数、pH、黏度及蛋黄颜色对鸡蛋呼吸强度影响最大。

Abstract: The changes of egg albumen and yolk quality during storage were closely related to respiration. In order to further clarify the relationship between egg internal quality and respiration intensity, this study selected the same species of eggs as the test samples. The respiratory intensity of egg was measured by respiration?determination instrument for correlation analysis of egg quality and respiration intensity. The effects of haugh unit(HU) ,egg albumen height, pH,viscosity, yolk index, yolk proportion and yolk color on respiration intensity were analyzed by SPSS 19.0 software.The results indicated that the correlation among haugh unit,egg albumen height, viscosity and respiration intensity was statistically significant(R = 0.763,P < 0.01;R = 0.826,P < 0.01;R = 0.840,P < 0.01); A negative correlation was observed between respiratory intensity and pH (R = -0.814,P < 0.01); there was a positive correlation between respiratory intensity with both yolk index(r = 0.634,P < 0.01) and yolk color(R = 0. 0.878,P < 0.01); However, the correlation of yolk proportion and respiration intensity was not statistically significant. In addition, there was a negative correlation between pH with viscosity (R = -0.990,P < 0.01) ,yolk index (R = -0.922,P < 0.01) and yolk color (R = -0.963,P < 0.01);there was a positive correlation between viscosity with both yolk index(R =0.904,P < 0.01) and yolk color (R = 0.0.968,P < 0.01);The correlation between yolk ratio and other parameters was smaller.It can be concluded that egg internal quality parameters haugh unit(HU),egg albumen height, pH , viscosity , yolk index and yolk color affect respiration intensity.
