Abstract

Researchers have recently been interested in employing nanoparticles (NPs) obtained from herbal extracts through green synthesis for various applications. This study investigated the detoxification of aflatoxins, which are toxic substances produced by molds Aspergillus flavus and Aspergillus parasiticus. The present work examined the levels of aflatoxins in hazelnut and peanut puree. Turkish black tea extract (BTE), Turkish green tea extract (GTE), green synthesized black tea-based iron oxide nanoparticles (BTFeONPs), and green tea-based iron oxide nanoparticles (GTFeONPs) were produced for aflatoxin removal. Characterizations and various antioxidant and antimicrobial activities of the tea extracts and iron oxide nanoparticles (FeONPs) were investigated. The aflatoxin levels of hazelnut puree used for this study were 6.57 ± 0.06 µg/kg for aflatoxin B1 and 13.03 ± 0.16 µg/kg for total aflatoxin, whereas the aflatoxin levels of (AFLB1) peanut puree were 7.79 ± 0.15 µg/kg for AFLB1 and 15.21 ± 0.12 µg/kg for total aflatoxin. Using soluble BTE resulted in a 40 to 50% decrease in aflatoxin levels in hazelnut and peanut purees, while soluble GTE led to a 30 to 45% decrease. Meanwhile, using BTFeONPs and GTFeONPs resulted in a 33 to 48% and 40 to 50% decrease, respectively, in aflatoxin levels in hazelnut and peanut purees.

利用绿茶和红茶提取物的生物合成氧化铁纳米颗粒解毒黄曲霉毒素

最近，研究人员对利用通过绿色合成从草药提取物中获得的纳米粒子（NPs）进行各种应用产生了浓厚的兴趣。黄曲霉毒素是由黄曲霉和寄生曲霉产生的有毒物质。本研究考察了榛子泥和花生泥中黄曲霉毒素的含量。制备了土耳其红茶提取物（BTE）、土耳其绿茶提取物（GTE）、绿色合成红茶氧化铁纳米粒子（BTFeONPs）和绿茶氧化铁纳米粒子（GTFeONPs），用于去除黄曲霉毒素。研究了茶叶提取物和氧化铁纳米粒子（FeONPs）的特性以及各种抗氧化和抗菌活性。本研究使用的榛子泥的黄曲霉毒素含量为 6.57 ± 0.06 µg/kg（黄曲霉毒素 B1）和 13.03 ± 0.16 µg/kg（黄曲霉毒素总量），而花生泥（AFLB1）的黄曲霉毒素含量为 7.79 ± 0.15 µg/kg（黄曲霉毒素 B1）和 15.21 ± 0.12 µg/kg（黄曲霉毒素总量）。使用可溶性 BTE 后，榛子泥和花生泥中的黄曲霉毒素含量降低了 40% 至 50% ，而可溶性 GTE 则降低了 30% 至 45%。同时，使用 BTFeONPs 和 GTFeONPs 可使榛子泥和花生泥中的黄曲霉毒素含量分别减少 33% 至 48% 和 40% 至 50%。
