Study on Application Effect of The Fresh Keeping CND of Non-sulfur Dioxide Special for Red Globe Grape

研究了非SO2型红地球葡萄专用保鲜剂CND的应用效果。结果表明:经过CND处理后,红地球葡萄还原糖、总酸、VC的3种营养指标总体消耗显著降低,品质保持较好。贮藏期间呼吸强度明显低于对照组,影响红地球葡萄品质的3种主要酶类均保持较低活跃水平。说明CND能较好的控制红地球葡萄的生理代谢,保鲜效果明显。

This paper studied on application effect of the fresh keeping CND of non-sulfur dioxide special for Red Globe grape.The results showed that it was descend clearly to the sugar,titration acid,VC in Red Globe grape by CND,the quality kept better.The breathe strength was obviously low than comparison in store,three kinds of enzymes kept lower active level of influence quality.Results showed that CND can control the better in the physiology metabolism of red earth grape,kept fresh effect obvious.
