The current study was planned to investigate the potential of polysaccharides-based nanoemulsion coatings to improve postharvest storage life of apple fruit. As per experimental plan of response surface methodology (RSM), 13 coating formulations were prepared; coatings were applied to fruit and stored at 20 °C for 14 days. The effects of coating on physicochemical, antioxidant capacity (%), total phenolic content and microbial counts in apple fruit and its juice were assed. The developed model showed non-significant (p > 0.05) lack of fit for all evaluated target response variables. Coefficients of determination (R²) ranging from 92.69 to 99.65% were obtained for these responses. The experimental results investigated in this study suggested that the nanoemulsion based on fenugreek and flax polysaccharide preserved overall quality attributes of apple fruit during storage as well as extended shelf life. Based on RSM, a formulation with a blend of 1.5 g fenugreek and 1.0 g flax polysaccharides was predicted to produce the most desirable effects for target responses, and no significant (p > 0.05) difference between experimental and predicted values. Hence, such an ecofriendly natural approach towards enhancing postharvest quality of fruits was explored to promote trade of organic produce and further investigation is needed regarding scaling and pilot-scale validation trials.

利用响应面法优化基于多糖的纳米乳剂及其在苹果采后贮藏中的应用

目前的研究计划旨在研究基于多糖的纳米乳剂涂料在改善苹果果实采后贮藏寿命方面的潜力。根据响应表面方法学（RSM）的实验计划，制备了13种涂料配方。将包衣涂在水果上并在20°C下保存14天。评估了包衣对苹果果实及其汁液的理化性质，抗氧化能力（％），总酚含量和微生物数量的影响。所开发的模型显示，对于所有评估的目标响应变量，均无显着性（p> 0.05）缺乏拟合。测定系数（R ²这些响应获得的范围为92.69至99.65％。在这项研究中研究的实验结果表明，基于胡芦巴和亚麻多糖的纳米乳剂在保存过程中保留了苹果果实的整体品质属性，并延长了保质期。基于RSM，预计1.5 g胡芦巴和1.0 g亚麻多糖的混合物会产生最理想的目标反应效果，并且 实验值和预测值之间无显着差异（p > 0.05）。因此，人们探索了一种提高水果采后质量的生态友好型自然方法，以促进有机农产品的贸易，并且需要进一步研究规模化和中试规模的验证试验。
