- 摘要:
- 以灰枣为试材,运用主成分和相关性分析方法,研究了不同干燥温度、不同干燥时间下灰枣外观品质及内在品质等相关指标的变化规律,以期为灰枣热风干燥提供参考依据。结果表明:1)随着烘干温度升高和时间的延长,灰枣还原糖、蔗糖、纤维素和淀粉含量在升高,但灰枣硬度、内聚性呈先下降再上升趋势,灰枣弹性呈先上升再下降再上升趋势。2)在温度为75 ℃下烘干时间为8 h处理下,灰枣的还原糖、蔗糖、纤维素、淀粉含量较高,灰枣的硬度、弹性达到最大值。
- Abstract:
- Taking Ziziphus jujuba,the changes of appearance quality and internal quality of jujube ash under different drying temperature and drying time were studied by principal component and correlation analysis method.The results showed that,1) With the extension of drying temperature and time,the contents of reducing sugar,sucrose,cellulose and starch increased,but the hardness and cohesion of Ziziphus jujuba showed a trend of decreasing and increasing.The elasticity of Ziziphus jujuba showed a trend of first increasing,then decreasing,and then increasing again.2) Under a drying time of 8 hours at a temperature of 75 ℃,the content of reducing sugar,sucrose,cellulose,and starch in Ziziphus jujuba was relatively high,and the hardness and elasticity of Ziziphus jujuba reached their maximum values.
