HPTLC-DPPH显色-像素分析快速测定酚类 抗氧化剂:以食用油和烘焙食品中TBHQ为例HPTLC-DPPH colorimetric-bioautographic image quantification of phenolic antioxidant: taking TBHQ in edible oil and baking foods as an example

open access: yesZhongguo youzhi, 2022
目前,酚类抗氧化剂TBHQ的常用检测方法存在前处理烦琐、耗时长、单次只能测定一个样品的问题,因此亟需建立一种高通量、快速准确的检测方法。为此,将高效薄层色谱(HPTLC)分离与1,1-二苯基-2-三硝基苯肼(DPPH)还原变色反应、图像像素定量分析相结合,建立了一种快速筛检酚类抗氧化剂TBHQ的方法。在此基础上,以食用油、面包和蛋糕为代表性样品,验证所建方法的实际应用性能。结果显示:所建方法检测TBHQ的检测限为70 ng/zone (35 mg/kg),定量限为140 ng/zone (70 mg ...
