利用色差仪估测番茄果实番茄红素含量的研究

Studies on Estimating Lycopene Content of Tomato Fruits by Using Color Difference Meter

利用色差仪评价了果实番茄红素含量差异明显的TA517、TA1527及E6203等番茄材料的果实颜色,采用HPLC技术测定了番茄红素含量,建立了果实颜色系数对番茄红素含量的回归方程,然后对28份番茄材料进行了番茄红素含量预测,进一步证实了3个果实颜色系数的回归方程得到的番茄红素含量的预测值与实际测定值符合程度高。结果表明,色差仪法具有简便、快速、成本低等特点,可以用来预测番茄红素含量。

In this study, tomato fruit color of the materials＇ TA517 ＇, ＇ TA1527 ＇ and ＇ E6203 ＇ were estimated by Chroma meter, and lycopene content were measured by HPLC. Regressive equations were developed and used to predict the lycopene content of 28 tomato materials. The lycopene content, measured by HPLC, was correlated with the color estimation, and the Ya＊/b ＊ , Y （ a ＊/b ＊ ） z, and YHue color factors produced the best regressions. An estimation of the lycopene content in tomatoes can be achieved by using a portable Chroma meter.
