| 中文摘要: |
| 目的 制备茶多酚(Tea Polyphenols，TP)、壳聚糖(Chitosan，CS)和百里香精油(Thyme Oil，TO)复合涂膜，探究其在圣女果保鲜中的应用效果。方法 通过单因素和正交试验，探讨不同TP、CS、TO质量分数配比所制复合涂膜以及浸泡时间对于圣女果的保鲜作用，得到复合涂膜最佳组合。通过测定感官及理化指标，评价复合涂膜最佳组合对圣女果保鲜效果的影响。结果 得到复合涂膜最佳组合，茶多酚的质量分数为0.3%，壳聚糖的质量分数为0.75%，百里香精油的质量分数为0.6%，浸泡时间为5 min。与对照组相比，按此条件处理的圣女果在贮藏结束时的质量损失率(6.12%)最低，感官评分(7.01)、可溶性固形物含量(6.27%)、还原糖含量(88.68 mg/g)、可滴定酸含量(0.49%)、维生素C含量(23.34 mg/100 g)、总黄酮含量(4.42 mg/g)均优于其他对照组。结论 该复合涂膜能有效维持圣女果在贮藏12 d内的品质，对于圣女果有较好的保鲜效果。 |

| The work aims to prepare tea polyphenols (TP), chitosan (CS) and thyme oil (TO) composite coating, and explore its application effect in the preservation of cherry tomatoes. The preservation effect of composite coatings prepared with different concentrations of TP, CS, and TO, as well as soaking time, on cherry tomatoes was investigated through single factor and orthogonal experiments to obtain the optimal combination of composite coatings. The effect of the optimal combination of composite coatings on the preservation of cherry tomatoes was evaluated by measuring sensory and physicochemical indicators. The optimal combination of the composite coating was:0.3% concentration of tea polyphenol, 0.75% concentration of chitosan, 0.6% concentration of thyme essential oil and 5 minutes of soaking time. Compared with the control group, the weight loss rate (6.12%) of the cherry tomatoes treated under these conditions was the lowest at the end of storage. Sensory score (7.01), soluble solids content (6.27%), reducing sugar content (88.68 mg/g), titratable acid content (0.49%), vitamin C content (23.34 mg/100 g), and total flavonoid content (4.42 mg/g) were all superior to other control groups. The composite coating can effectively maintain the quality of cherry tomatoes during 12 days of storageand has a good preservation effect on cherry tomatoes. |
