Feasible discussion about aflatoxin B1 determination in Tartary Buckwheat products by HPLC

摘要

Feasibility of determining aflatoxin B1 in TartaryBuckwheat products by HPLC was studied by analyzing the Standard curve, sensitivity, accuracy, precision, the system error and sensitivity. The results showed that using HPLC to determine the aflatoxin B1 in TartaryBuckwheat products is feasible, the detection range was 0.20-200.00μg /L, determination coefficient R2 was 0.9968, the relative error was 7.09%, 5.28%, 4.55%, 0.23% respectively, the average recovery of standard addition in buckwheat core flour was 84.58%, the variation coefficient of buckwheat noodles, buckwheat soup and buckwheat tea was 9.36%, 5.25%, 8.22% respectively, and the detection sensitivity reached 0.20 μg /L.
