Biodegradable alternatives for the control of in fig fruit were tested with the application of coatings based on chitosan (CS) and propolis (P). To potentiate the fungicidal effect, nanoparticles of these two (CSNPs and PNPs) were also considered. The objectives of this research were to evaluate the effect of different formulations on: (a) the ripening process of the fig, (b) the incidence of and the production of aflatoxins, and (c) the acceptance of the treated fruit by a panel. The nanostructured coatings did not influence the ripening process of the fruit during the 12 days of storage, however, the antioxidant activity increased by approximately 30% with the coating CS + PNPs + P. The figs treated with CS + CSNPs + PNPs + P, inhibited the growth of the fungus by about 20% to 30% under laboratory and semi-commercial conditions. For all treatments, the aflatoxin production was lower than 20 ppb compared to the control with values of c.a. 250 ppb. The sensory quality was acceptable among the panel. The edible coatings can be a non-toxic alternative for post-harvest preservation and the consumption of fig fruit. The next step will be its inclusion and evaluation at a commercial level in packing houses.
测试了基于壳聚糖（CS）和蜂胶（P）的涂层在控制无花果果实[此处原文缺失一种真菌名称]方面的可生物降解替代品。为增强杀菌效果，还考虑了这两种物质的纳米颗粒（CSNPs和PNPs）。本研究的目的是评估不同配方对以下方面的影响：（a）无花果的成熟过程，（b）[此处原文缺失一种真菌名称]的发生率和黄曲霉毒素的产生，以及（c）一组人员对处理过的果实的接受程度。在12天的储存期内，纳米结构涂层并未影响果实的成熟过程，然而，CS + PNPs + P涂层使抗氧化活性提高了约30%。在实验室和半商业条件下，用CS + CSNPs + PNPs + P处理的无花果使真菌生长抑制了约20%至30%。对于所有处理，与对照（约250 ppb的值）相比，黄曲霉毒素产量低于20 ppb。在该组人员中，感官品质是可接受的。可食用涂层对于无花果果实的采后保鲜和消费而言可能是一种无毒替代品。下一步将是在包装厂进行商业层面的纳入和评估。
