提出一种新型茶多酚含量检测方法,探讨利用扫描仪采集样品显色溶液的色度值,测定茶多酚含量的可能性。研究结果表明:显色液的色度值与茶多酚浓度具有良好的线性相关性,所提出的新型茶多酚含量测定方法具有成本低、速度快、效率高、对环境条件的要求相对宽松等特点,通过进一步完善操作规范,该方法具有良好的应用前景。
A new detection method of tea polyphenols was proposed to explore the possibility of using the scanner to collect the colorimetric value of the sample chromogenic solution and determine the content of tea polyphenols. The results showed that the color value of the color developing liquid had a good linear correlation with the concentration of tea polyphenol, and the proposed method for determining the content of tea polyphenol had the advantages of low cost, high speed, high efficiency and relatively relaxed requirements on environmental conditions And other characteristics, by further improving the operation of the standard, the method has good prospects.
