织锦巴非蛤斧足颜色与总类胡萝卜素含量相关分析

Correlation analysis of the color and total carotenoid content in Paphia textile foot tissue

斧足是织锦巴非蛤重要的食用部位。本研究检测了94个织锦巴非蛤斧足的总类胡萝卜素含量(TCC)和3个颜色指标L*(明暗度)、a*(红绿值)、b*(黄蓝值),发现织锦巴非蛤斧足总类胡萝卜素含量和颜色指标在不同个体之间存在较大差异。相关性分析表明,织锦巴非蛤斧足的总类胡萝卜素含量与颜色指标L*、a*、b*之间相关极显著(P<0.01),相关系数分别为:–0.546、0.569、0.449。本研究表明,斧足颜色越深,其类胡萝卜素含量也越高可能是一个普遍规律,这对我们接下来选育高类胡萝卜素含量贝类提供了一种直观的参考指标。

Foot tissue is an important edible part of Paphia textile. This study examined the total carotenoid content（TCC） and color index L＊（brightness）, a＊（values of red, green）, and b＊（values of yellow, blue） of 94 P. textile foot tissue samples. There are huge differences in TCC and color index among individuals. Correlation analysis showed that P. textile foot tissue of TCC and color index, L＊, a＊, and b＊, have high significant correlation（P0.01）, with the correlation coefficients being –0.546, 0.569, and 0.449, respectively. This study illustrated a potential universal law, i.e., the deepness of the color of the foot tissue is directly proportional to the content of carotenoid, which provides important reference data for selecting high-content carotenoid in P. textile breeding.
