基于PG含量变化研究软枣猕猴桃采摘时期及贮藏条件

The Best Harvest Period and Storage Conditions of Actindia Arguta Based on Changes of PG

中国东北地区软枣猕猴桃每年8～9月成熟,含有丰富的Vc和营养物质,而耐贮性较差。本文以野生软枣猕猴桃为试验材料,根据软枣猕猴桃中PG含量变化研究软枣猕猴桃最佳采摘时间和最佳贮藏条件。研究表明,中国辽宁省鞍山地区野生软枣猕猴桃最适宜采摘期宜选在8月末至9月初,果实果胶酶活性1010.72μg/h·g左右。

Actinidia arguta of northeastern China bears fruits in August and September every year. The fruit isrich of VC and other nutrition but it＇s hard to main its freshness. With wild Actinidia arguta as test material, thebest time for its harvest and the optimal conditions for storage based on the change of PG content of the fruit were an-alyzed in the paper. According to the study, the best time to harvest Actinidia arguta grown in the area of Anshan, Li-aoning Province is from end of August to the beginning of September. The fruits at this period have pectinase con-tent of 1010.72 μg/h·g.
