| titleOfInvention | A method suitable for rapid detection of aflatoxins in large batches of edible oil samples |
| abstract | The invention discloses a low-cost method suitable for rapid detection of aflatoxin in a large batch of edible oil samples. The steps are as follows: 1) After the edible oil sample to be tested is diluted with n-hexane, it is subjected to a solid phase extraction column of pine pollen. Load the sample to extract and enrich the aflatoxin in the sample; 2) After the sample loading, the pine pollen solid-phase extraction cartridge is cleaned to remove the interfering substances, desorbed and reconstituted, and the obtained solution is the Aspergillus flavus in the edible oil. 3) The aflatoxin content in the sample was rapidly detected by the external standard method and high performance liquid chromatography-fluorescence detector. The pretreatment process of the invention can remove a large number of substrates in the edible oil, has good purification effect, and has a good recovery rate of aflatoxin. The low-cost and rapid detection of large quantities of edible oil samples is realized, and the detection sensitivity and accuracy are high, and the reproducibility is good. |
