| 中文摘要: |
| 为了研究壳聚糖-植物提取物复合涂膜对樱桃番茄保鲜效果的影响，利用壳聚糖与不同浓度的丁香或荷叶提取物制备复合膜溶液对樱桃番茄进行涂膜处理，考察樱桃番茄在4 ℃冷库贮藏过程中的硬度、失重率、腐烂率和营养成分的变化。结果表明：经壳聚糖-植物提取物复合涂膜处理后，樱桃番茄的保鲜效果有了明显的提升，较好地保持了果实色泽和新鲜度；贮藏56 d时，10 g/L壳聚糖和10 g/L丁香提取物复合涂膜处理的果实硬度最高，为220.8 g，腐烂率比空白对照组果实降低了10.00个百分点，失重率降低了0.06个百分点，与其他处理组相比，该处理抑制可溶性固形物、可滴定酸、VC等营养成分流失的效果最好。该研究为开发新型果蔬生物保鲜剂提供了理论依据。 |
| 英文摘要: |
| In order to study the effects of chitosan-plant extracts composite coating on the fresh-keeping effects of cherry tomatoes, the composite film solution prepared by chitosan and different concentrations of clove/lotus leaf extracts was used for coating treatments, and the changes of hardness, weight loss rates, decay rates and nutritional components of cherry tomatoes during cold storage at 4 ℃ were investigated. The results showed that the fresh-keeping effects of cherry tomatoes were significantly improved after chitosan-plant extracts composite coating treatments, and the fruits color and freshness were well maintained. The hardness of 10 g/L chitosan-clove(10 g/L) extract treated fruits was the highest with a value of 220.8 g, the fruits decay rate was 10.00 percentage points lower, and the weight loss rate was 0.06 percentage points lower compared with blank control group, and the effects in inhibiting the loss of soluble solids, titratable acid, VC and other nutrients loss were the best compared with other treatments groups. This study provided a theoretical basis for developing novel biological preservatives for fruits and vegetables. |
