Abstract

This study investigated the role of irradiation with a high-energy electron beam in reducing mycotoxin levels of African nutmeg powder (ANP) samples. African nutmeg was procured from a local market in Accra, Ghana, cleaned, milled, packaged and irradiated using electrons of energy 9 MeV at doses of 2, 4, 6 and 8 kGy. Un-irradiated ANP served as a control. Mycotoxin levels of the treated samples were determined using appropriate standard methods. Aflatoxins B1 (AFB1) and B2 (AFB2) as well as ochratoxin A (OTA) were detected in the nutmeg samples. Irradiation significantly (p < 0.05) reduced mycotoxin levels of the ANP with increasing doses. Aflatoxins G1 and G2 were not detected in any of the samples. A dose of 8 kGy was effective in reducing the mycotoxin levels below the permissible limit in food. This suggests that a high-energy electron beam is effective in reducing mycotoxin levels in African nutmeg powder.

利用高能电子束降低非洲肉豆蔻（Monodora myristica）粉末中的霉菌毒素含量。

本研究调查了高能电子束辐照在降低非洲肉豆蔻粉（ANP）样品霉菌毒素含量方面的作用。非洲肉豆蔻是从加纳阿克拉当地市场采购的，经过清洗、研磨、包装后，使用能量为 9 MeV 的电子进行辐照，辐照剂量分别为 2、4、6 和 8 kGy。未经辐照的 ANP 作为对照。采用适当的标准方法对处理过的样品进行霉菌毒素含量测定。在肉豆蔻样品中检测到了黄曲霉毒素 B1（AFB1）和 B2（AFB2）以及赭曲霉毒素 A（OTA）。辐照可明显（p

期刊介绍： Food Additives & Contaminants: Part A publishes original research papers and critical reviews covering analytical methodology, occurrence, persistence, safety evaluation, detoxification and regulatory control of natural and man-made additives and contaminants in the food and animal feed chain. Papers are published in the areas of food additives including flavourings, pesticide and veterinary drug residues, environmental contaminants, plant toxins, mycotoxins, marine biotoxins, trace elements, migration from food packaging, food process contaminants, adulteration, authenticity and allergenicity of foods. Papers are published on animal feed where residues and contaminants can give rise to food safety concerns. Contributions cover chemistry, biochemistry and bioavailability of these substances, factors affecting levels during production, processing, packaging and storage; the development of novel foods and processes; exposure and risk assessment.
