Abstract There are different colorimetric methods, with various analysis principles and phases, for the estimation of phytic acid content in agricultural products. Maize genotypes may possess a wide range of oil content, which is considered as a factor affecting the results of phytic acid analyses. Elaborative studies are needed to examine these methods to clarify the effect of oil content on the results, especially in the sample sets with varying oil concentrations. We utilized 4 different colorimetric methods; namely, AOAC, Wade, Chen and Haug-Lantzsch (H-L), to estimate phytic acid content in 19 maize genotypes, classified as having high (>7 %, n = 7) normal (3–5 %, n = 6) and low (

测定玉米原粉和油浸面粉样品中植酸含量的比色法比较

摘要 农产品中植酸含量的估算有多种比色法，分析原理和阶段各不相同。玉米基因型可能具有广泛的含油量，这被认为是影响植酸分析结果的一个因素。需要详细研究来检查这些方法，以阐明含油量对结果的影响，尤其是在具有不同含油浓度的样品组中。我们使用了 4 种不同的比色方法；即 AOAC、Wade、Chen 和 Haug-Lantzsch (HL)，用于估计 19 种玉米基因型中的植酸含量，归类为具有高 (>7 %, n = 7) 正常 (3–5 %, n = 6) 和低的 （
