In the present study, the effectiveness of atmospheric pressure cold plasma (APCP) in reducing aflatoxins (AFB₁, AFB₂, AFG₁, and AFG₂) and total aflatoxin in naturally contaminated and spiked mixed nuts as well as in standard toxin solutions was investigated. According to the results, after 16 min of APCP treatment, AFB₁ levels decreased by 24.6 % in naturally contaminated nuts and by 88.4 % in spiked samples, while an 80.9 % reduction was observed in standard toxin solutions after just 2 min. The total aflatoxin levels decreased by 22.7 % in naturally contaminated samples within 16 min, while this rate was 72.6 % in spiked samples. Considering the standard toxin solution, a rapid 76.3 % decrease was observed in total aflatoxin level in just 2 min. While APCP slightly affected moisture, free fatty acid, and peroxide values, other quality parameters remained stable. These results demonstrate that mycotoxin form and food matrix significantly influence detoxification efficiency.

Cereal foods are very susceptible to aflatoxins (AFs) pollution, posing significant health hazards to people. This necessitates the development of robust sorbent for enriching and sensitively detecting AFs in cereal foods. Herein, two heterocyclic hyper-crosslinked polymers (HCP-1 and HCP-2) sorbents were developed using benzotriazole as monomer for the first time. Benefiting from rich NH groups, HCP-1 exhibited prominent adsorption for AFs through hydrogen bond interaction. An HCP-1 based solid phase extraction method in conjunction with high performance liquid chromatography-fluorescence detector was built to effectively detecting four AFs (AFB1, AFB2, AFG1 and AFG2) in millet and mung bean. The limit of quantification of the method (0.02-1.00 ng g^-1) was below the European Union levels (2 ng g^-1 for AFB1 and 4 ng g^-1 for the sum of four AFs). Satisfactory recoveries were achieved, ranging from 87.5 to 116 %, with relative standard deviation below 7.6 %.

Coix seed is easy to be contaminated with aflatoxins. To find out its detoxification strategy and explore its storage environment affecting the contents of AFB₁, AFB₂, AFG₁, and AFG₂, 23 batches of coix seed samples were collected, in which nine batches of samples were selected to make mildewed by the method of artificial cultivation and natural mycotoxin production. These coix seed samples were further processed with plain-frying and bran-frying, respectively. Commercial coix seed samples had a high probability of containing AFTs with a detection rate of 87.0% and a rejection rate of 30.4%. The contents of AFTs in coix seed samples could be significantly decreased by both plain-frying and bran-frying processing. Compared with plain-frying, bran-frying processing can reduce the contents of AFTs in coix seed more effectively. Therefore, promoting the use of bran-frying processing will help reduce mycotoxin pollution in the food.
