For sale in the domestic market, Hass avocados are kept in non-biodegradable plastic nets and stored at an ambient temperature. The fungus can cause important losses at this stage. Consequently, formulations based on polylactic acid (PLA)/poly (butylene adipate-co-terephthalate) (PBAT) 60/40 biodegradable blends added with pine essential oil (PEO) at 10, 12, 14, and 20% and coated with 1% chitosan (CH) were used for the elaboration of nets, which were evaluated on and on nutrient media and fruit and on the ripening behavior of Hass avocados at ambient temperature. The spore germination stage of was the most extensively damaged (78% inhibition). The incidence of anthracnose was notably reduced by almost 80% in the avocados stored in the 60/40 PLA/PBAT nets coated with 1% CH. The overall values regarding weight loss, °Brix, and dry matter were c.a. 23.5%, 7.5, and 24.5%, respectively. The changes in firmness, color, and CO production were particularly associated with the initial harvest index and storage temperature rather than with the nets. In future research, essays on nets should include evaluations at the commercial levels.
在国内市场销售的哈斯鳄梨用不可生物降解的塑料网包装，并在环境温度下储存。在此阶段，这种真菌会造成重大损失。因此，基于聚乳酸（PLA）/聚（己二酸丁二醇酯 - 对苯二甲酸丁二醇酯）（PBAT）60/40生物可降解共混物并添加10%、12%、14%和20%的松树精油（PEO）且涂覆1%壳聚糖（CH）的配方被用于制作网，这些网在营养培养基、水果上以及在环境温度下对哈斯鳄梨的成熟行为进行了评估。该真菌的孢子萌发阶段受损最为严重（抑制率达78%）。在涂覆1%CH的60/40 PLA/PBAT网中储存的鳄梨，炭疽病发病率显著降低了近80%。关于重量损失、糖度和干物质的总体数值分别约为23.5%、7.5和24.5%。硬度、颜色和二氧化碳产生的变化尤其与初始收获指数和储存温度有关，而非与网有关。在未来的研究中，关于网的试验应包括商业层面的评估。
