| 摘 要： | 目的]为研究冻藏期间冬枣品质的变化。方法]利用-70℃对冬枣进行速冻后,采用-40℃、-18℃、-10℃和-4℃进行冻藏,就不同冻藏时期冬枣的品质特性变化进行研究。结果]-70℃速冻后,合适的冻藏温度为-18℃和-40℃,-40℃冻藏能使冬枣的保鲜期10个月以上,而-18℃冻藏能保鲜冬枣6个月以上。结论]速冻冻藏能有效维持冬枣的品质特性,如延缓含水量、可溶性糖、维生素C和有机酸含量的下降,保持较高的硬度和延缓花青素含量的升高。 |

| Abstract: | Objective] The research aimed to study the changes of the quantity of winter jujube during frozen storage period.Method] The quality changes of winter jujube at different frozen storage temperature of-40 ℃,-18 ℃,-10 ℃ and -4 ℃ resp.were studied after quick frozen at-70 ℃.Result] After quick-frozen at -70 ℃,the suitable frozen storage temperature were-18 ℃ and-40 ℃.The preservation period of winter jujube could be prolonged for more than 10 months in frozen storage at-40 ℃ and more than 6months at-18 ℃.Conclusion] Quick-frozen storage could maintain the quality of winter jujube effectively,such as delaying the decrease of water content,soluble sugar,Vc and organic acid content,keeping higher hardness and delaying the increase of anthocyanin content. |
