- 摘要:
- 以新疆和田冬枣为研究对象，采用低温冷藏方法，研究了不同药剂处理对冬枣贮藏保鲜的效果。结果表明：氯化钙和甲基托布津处理能抑制冬枣的腐烂，对贮藏保鲜有利。贮藏56 d后，以0.10%甲基托布津溶液处理其腐烂率最低（48.40%），维生素C含量最高（58.864 6 mg/100g）；1%氯化钙和0.10%甲基托布津溶液处理其失重率最小（2.49%）、可溶性固形物含量最高（17.75%）；0.05%甲基托布津溶液处理其果实硬度最大（8.68 Pa）；1%氯化钙和0.05%甲基托布津溶液处理其可滴定酸含量最低（0.33 g/100mL）。综合考虑，以采用0.10%的甲基托布津溶液处理的效果较好，能较好地保存冬枣的营养成分，延长冬枣贮藏保鲜期。
- Abstract:
- The effect of different medicament treatments with the cold storage conditions (0-4℃ temperature，90%-95% relative humidity) on fresh-keeping storage of winter jujube in Hetian area was studied.The results showed that the treatment of calcium chloride and Topsin-M could inhibit the decay of winter jujube and was beneficial to storage.After stored 56 days，the fruits had the lowest decay rate (48.40%) and the highest vitamin C content (58.864 6 mg/100g) with treatment of 0.10% thiophanate methyl solution.When treatment with 1% calcium chloride and 0.10% thiophanate methyl solution，the jujube had the lowest weight rate (2.49%) and highest soluble solids content (17.75%).The fruits had the highest fruit firmness (8.68 Pa) with treatment of 0.05% thiophanate methyl solution.It had the lowest titratable acid content (0.33 g/100mL）with the treatment of 1% calcium chloride and 0.05% thiophanate methyl solution.Considering all these factors，the 0.10% thiophanate methyl solution was the best selection.It could effectively preserve the nutrients and prolong the storage period of winter jujube.
