Ultraviolet-LED irradiation effectively detoxified aflatoxin B1 in groundnut oils
SCIENCEASIA(2020)
Abstract
This study aimed to evaluate the quality of aflatoxin B1-detoxified unrefined groundnut oils. Detoxification of aflatoxin B1 (AFB1) in unrefined groundnut oils was performed by ultraviolet light-emitting diodes (UV-LED) irradiation. Ten samples of unrefined groundnut oils were subjected to UV-LED treatment before the measurements of AFB1 content, fatty acid compositions and chemical properties. The 20-min treatment reduced AFB1 content by 99%. Both acid and peroxide values of the oil samples showed little changes after the samples were treated with UV-LED irradiation. GC-MS results showed that 21 types of fatty acid were detected in the untreated oil samples. Minor changes in the levels of fatty acid were also observed after the 20-min treatment. The results proved that UV-LED irradiation effectively reduced AFB1 content in the unrefined groundnut oils and maintained the oil quality. It is a promising strategy for detoxification of AFB1 in groundnut oil.
