Abstract

This study monitored concentrations of both pesticides 2,4-dichlorophenoxyacetic acid (2,4-D) and procymidone, and mycotoxin ochratoxin A (OTA) in stages of the winemaking process. Sampling was carried out in the usual vinification process of red wine in a winery between the steps to obtain must and alcoholic fermentation. The highest transference of contaminants in the process occurred in the crushing step to 2,4-D (100%) and maceration to OTA and procymidone (100%). Removal of contaminants in the winemaking process corresponded to 100%, with a half-life (T1/2) longer for procymidone (216.5 h) and shorter for 2,4-D (38.5 h) and OTA (96 h). The processing factors (PFs) (0) for the contaminants, together with the data obtained, characterize winemaking as a process of reducing mycotoxin and pesticides. Results highlight the importance of fermentation to reduce contaminants and that yeasts promote detoxification
酿酒过程中霉菌毒素和农药的监测
本研究监测了酿酒过程中农药2,4-二氯苯氧乙酸(2,4- d)和原酰米酮以及霉菌毒素赭曲霉毒素A (OTA)的浓度。在酿酒厂红葡萄酒的常规酿造过程中,在获得葡萄酒和酒精发酵的步骤之间进行采样。在这个过程中,污染物的最高转移发生在粉碎步骤到2,4- d(100%)和浸渍到OTA和procymidone(100%)。在酿酒过程中,污染物的去除率达到100%,其中原酰米酮的半衰期(T1/2)较长(216.5 h), 2,4- d和OTA的半衰期较短(38.5 h)和OTA的半衰期(96 h)。污染物的处理因子(PFs)(0)与所获得的数据表明,酿酒过程是一个减少霉菌毒素和农药的过程。结果强调了发酵对减少污染物和酵母促进解毒的重要性
