The present study was aimed to determine the effects of carboxymethyl cellulose (CMC)/garlic essential oil (GEO) composite coatings in improving the quality of strawberries stored at 20°C and 35-40% RH. To find the effects of CMC/GEO composite coatings, strawberries were coated with CMC, CMC+GEO (1%), CMC+GEO (2%), CMC+GEO (3%) and stored, while the uncoated strawberries were taken as control during storing. The effectiveness of CMC/GEO composite coatings was evaluated by measuring their weight loss, decay percentage, ascorbic acid, total phenols, anthocyanins, titratable acidity, total soluble solids and sensory evaluation. After 6days of storage, CMC+GEO (2%) composite coatings was found very effective in decreasing the senescence and maintaining the nutritional contents of strawberries. Results of this study confirm that CMC/GEO composite coatings can be used to improve the quality of strawberries.
本研究旨在确定羧甲基纤维素（CMC）/大蒜精油（GEO）复合涂层在提高 20°C 和 35-40%相对湿度下储存的草莓品质方面的作用。为了研究 CMC/GEO 复合涂层的作用，将草莓用 CMC、CMC+GEO（1%）、CMC+GEO（2%）、CMC+GEO（3%）进行涂层处理，并在储存过程中，将未涂层的草莓作为对照。通过测量失重、腐烂率、抗坏血酸、总酚、花青素、可滴定酸度、总可溶性固形物和感官评价来评估 CMC/GEO 复合涂层的效果。在储存 6 天后，发现 CMC+GEO（2%）复合涂层非常有效地延缓了草莓的衰老并保持了其营养成分。本研究结果证实，CMC/GEO 复合涂层可用于提高草莓的品质。
