To carry out this work, latex from was obtained for the production of coatings, the characteristics of the produced coatings were analyzed, and their application on dried figs was evaluated. Work was conducted to obtain latex and produce coatings, optimizing the mixture and determining its properties. Additionally, the shelf life of coated fruits was studied. The results showed that the coatings had a milky white color, a thickness between 0.04 mm and 0.09 mm, a moisture content close to 25%, and a water solubility ranging from 80% to 98.73%. The 10% latex coatings showed better elasticity and resistance, being selected for the shelf life study. The optimal formulations selected were 28, 29, and 31, all with 10% latex. These coatings exhibited interesting antimicrobial activities against bacteria , , and and antifungal activity against , , , and . When applied to dried figs, it was observed that the appearance of the figs did not visibly change. Antioxidant activity was highest in batch 28, which also showed less microbiology and lower hardness at 60 days. Thus, coatings not only helped maintain the natural color of the fruits but also preserved their freshness and overall quality for a longer period. This makes them an effective and sustainable solution for the food industry.
为开展这项工作，获取了[来源未提及]的乳胶用于涂料生产，分析了所生产涂料的特性，并评估了其在干无花果上的应用。开展了获取乳胶和生产涂料的工作，优化了混合物并确定其性能。此外，还研究了涂覆水果的保质期。结果表明，这些涂料呈乳白色，厚度在0.04毫米至0.09毫米之间，水分含量接近25%，水溶性在80%至98.73%之间。10%乳胶涂料表现出更好的弹性和抗性，被选用于保质期研究。所选的最佳配方为28、29和31，均含10%乳胶。这些涂料对[细菌名称未明确]、[细菌名称未明确]和[细菌名称未明确]表现出有趣的抗菌活性，对[真菌名称未明确]、[真菌名称未明确]、[真菌名称未明确]和[真菌名称未明确]表现出抗真菌活性。当应用于干无花果时，观察到无花果的外观没有明显变化。批次28的抗氧化活性最高，在60天时微生物数量也较少且硬度较低。因此，涂料不仅有助于保持水果的天然色泽，还能在更长时间内保持其新鲜度和整体品质。这使其成为食品工业中一种有效且可持续的解决方案。
