峨眉含笑精油对冬枣保鲜的研究

研究在常温条件下不同浓度的峨眉含笑精油处理对冬枣的生理变化及保鲜效果的影响，结果表明：峨眉含笑精油处理对冬枣的保鲜有显著的效果。其中4μg·g^-1的峨眉含笑精油处理有效地降低冬枣果实的烂果率和失水率，提高POD活性；对Vc和还原性糖的含量的下降也有抑制作用。所以4μg·g^-1浓度的蛾眉含笑精油对冬枣的处理可以延长常温下冬枣的贮藏时间。

Study of the Essential Oil of Michelia wilsonii Finet et Gagnep on the Preservation of Zizyphusjujuba Mill

The effect of different concentration of the essential oil of Michelia wilsonii Finer et C, agnep on the preservation of Zizyphusjujuba Mill was studied.
