The need for safe and quality food, free from the presence of hazardous contaminants such as mycotoxins is an on-going and complex challenge. Cold atmospheric pressure plasma (CAPP) has the potential to contribute to achieving this goal. Decontamination efficacy of CAPP against six of the most common mycotoxins found in foods and feedstuffs was assessed herein. Concentration reduction of up to 66% was achieved in maize for both aflatoxin B and fumonisin B. Degradation products were detected only in the case of aflatoxin B and zearalenone and were tested on human hepatocarcinoma cells with no increase in cytotoxicity observed. Analysis of treated maize revealed substantial changes to small molecular mass components of the matrix. While CAPP shows promise in terms of mycotoxin detoxification important questions concerning potential changes to the nutritional and safety status of the food matrix require further investigations.
对安全和高质量食品的需求，使其不含真菌毒素等有害污染物，这是一个持续存在且复杂的挑战。冷大气压等离子体（CAPP）有可能有助于实现这一目标。本文评估了 CAPP 对六种在食品和饲料中最常见的真菌毒素的去污效果。在玉米中，黄曲霉毒素 B 和伏马菌素 B 的浓度降低了高达 66%。仅在黄曲霉毒素 B 和玉米赤霉烯酮的情况下检测到降解产物，并且在人肝癌细胞上进行了测试，未观察到细胞毒性增加。对处理过的玉米进行分析表明，基质中小分子质量成分发生了重大变化。虽然 CAPP 在真菌毒素解毒方面具有潜力，但有关食品基质的营养和安全状况可能发生变化的重要问题仍需要进一步研究。
