The effect of the application of chitosan- coatings emulsified with beeswax (0, 0.5, 1, 1.5 and 2%) during storage of L. (cv Anwar Ratol) was investigated. Particle size of emulsions was reduced significantly with an increase in beeswax concentration. Water vapor permeability of the coatings was reduced by 43.7% with an increase in concentration of beeswax to 2%. The coated mangoes (at all concentrations of beeswax) exhibited reduced weight loss, delayed firmness loss, minimized pH change, maintained the total soluble solid contents, and retained free radical scavenging activity and total phenolic contents when stored at 18 °C and 75 ± 5% R.H. The best results were produced with a formulation containing 2.0% beeswax. Antimicrobial properties of chitosan and coatings were also improved with an increase in beeswax concentration and remarkably reduced the disease incidence in mangoes. In conclusion, beeswax-emulsified chitosan- coatings can be effectively used to increase the shelf life and marketable period of mangoes.
研究了在“安瓦尔·拉托尔”芒果贮藏期间，应用含0%、0.5%、1%、1.5%和2%蜂蜡乳化的壳聚糖涂层的效果。随着蜂蜡浓度的增加，乳液的粒径显著减小。当蜂蜡浓度增加到2%时，涂层的水蒸气透过率降低了43.7%。在18℃和相对湿度75±5%的条件下贮藏时，涂覆的芒果（在所有蜂蜡浓度下）均表现出失重减少、硬度损失延迟、pH变化最小、总可溶性固形物含量保持不变，并保留了自由基清除活性和总酚含量。含2.0%蜂蜡的配方效果最佳。壳聚糖和涂层的抗菌性能也随着蜂蜡浓度的增加而提高，并显著降低了芒果的发病率。总之，蜂蜡乳化的壳聚糖涂层可有效用于延长芒果的货架期和适销期。
