The purpose of this study was to investigate the effects of certain essential oils (star anise, lemon leaves, marjoram, fennel, and lavender) on the fungal growth of and and their production of aflatoxin B1 (AFB1). The degree of suppression of the aflatoxigenic strains' growth and their production of AFB1 is mainly affected by the kind and the concentration of the tested essential oils (EOs). Star anise essential oil had the lowest minimum inhibitory concentration (0.5 and 1.0 μL/mL) against and , respectively, so it was the best among the five different oils. The study of liquid chromatography with tandem mass spectrometry revealed that star anise EO resulted in a 98% reduction in AFB1 without a breakdown of AFB1 products after treatment thus the complete removal of AFB1 was done without any toxic residues. The combination showed a synergistic effect, the combinational treatment between γ-irradiation at a low dose (2 kGy) and star anise EO at concentrate 0.5 μL/g destroyed inoculated (individually) in sorghum and peanut, respectively throughout the storage period (8 weeks).
本研究旨在探讨某些精油（八角、柠檬叶、马郁兰、茴香和薰衣草）对 和 的真菌生长及其黄曲霉毒素 B1（AFB1）产生的影响。抑制产毒菌株生长及其产生 AFB1 的程度主要受测试精油（EO）的种类和浓度的影响。八角精油对 和 分别具有最低的最小抑菌浓度（0.5 和 1.0 μL/mL），因此在这五种不同的油中表现最好。液相色谱串联质谱研究表明，八角精油处理后 AFB1 减少了 98%，而 AFB1 产物没有分解，因此在没有任何有毒残留物的情况下完全去除了 AFB1。该组合显示出协同作用，低剂量（2 kGy）γ 辐射与八角精油浓缩物 0.5 μL/g 的联合处理分别破坏了接种在高粱和花生中的 （单独），在整个储存期（8 周）内。
