Mycotoxin elimination is one of the significant concerns in the food industry. Cold atmospheric plasma (CAP) is a novel non-thermal method with high potential in this regard. This study aimed to evaluate the dielectric-barrier discharge (DBD) cold plasma effect on fresh-cut apple slices contaminated with patulin. The contaminated slices were subjected to a 17-23 kV range of DBD for 2.5-10 min and stored for 14 days in the refrigerator. This treatment eliminated the patulin and total viable count (TVC) by 23 kV power and 2.5- and 8.5-min exposure. The polyphenol oxidase (PPO) activity also decreased by 12 %, 47 %, and 28.5 % in the 1st, 7th, and 14th days of storage, respectively. Along with the moisture and vitamin C increment, the phenolics and browning index (BI) declined, which shows the overall acceptance increment. This study demonstrated the potential of CAP in improving the quality and shelf-life of ready-to-eat products.
霉菌毒素去除是食品工业中的重大关注点之一。冷大气等离子体（CAP）是一种在这方面具有巨大潜力的新型非热方法。本研究旨在评估介质阻挡放电（DBD）冷等离子体对被展青霉素污染的鲜切苹果片的影响。将受污染的切片置于17 - 23 kV范围的DBD下处理2.5 - 10分钟，然后在冰箱中储存14天。该处理通过23 kV功率以及2.5分钟和8.5分钟的暴露消除了展青霉素和总活菌数（TVC）。在储存的第1天、第7天和第14天，多酚氧化酶（PPO）活性分别下降了12%、47%和28.5%。随着水分和维生素C含量的增加，酚类物质和褐变指数（BI）下降，这表明整体可接受性提高。本研究证明了冷大气等离子体在改善即食产品质量和保质期方面的潜力。
