Apergillus carbonarius and Aspergillus niger are the principal fungi that attack table grapes, and they are responsible for producing and contaminating these fruits with ochratoxin A. Packaging containing essential oils from Ocimum gratissimum L. and Ocimum basilicum L. encapsulated in poly(lactic acid) (PLA) nanofibers were produced, the antifungal and antiocratoxigenic activities against A. carbonarius and A. niger were evaluated in vitro and in vivo, and the effect of these packages on the quality of table grapes was determined. The nanofibers were produced by the Solution Blow Spinning technique and characterized by Scanning Electron Microscopy and Thermogravimetric Analysis. Fungal contamination and ochratoxin A production were significantly controlled by PLA nanofibers containing the essential oils and the physicochemical parameters of the grapes were preserved, preserving the quality and the shelf life of the fruit. Therefore, the active packaging developed herein has potential and may be suitable for application in fruits.
炭角菌和黑曲霉是攻击酿酒葡萄的主要真菌，它们负责产生并污染这些水果中的赭曲霉毒素 A。我们制备了含有罗勒（Ocimum gratissimum L.）和甜罗勒（Ocimum basilicum L.）精油的聚乳酸（PLA）纳米纤维的包装，评估了其在体外和体内对炭角菌和黑曲霉的抗真菌和抗赭曲霉毒素活性，并确定了这些包装对酿酒葡萄质量的影响。纳米纤维是通过溶液吹纺技术制备的，并通过扫描电子显微镜和热重分析进行了表征。含有精油的 PLA 纳米纤维显著控制了真菌污染和赭曲霉毒素 A 的产生，并保持了葡萄的理化参数，从而保持了水果的质量和货架期。因此，本文开发的活性包装具有潜力，可能适用于水果的应用。
