摘要
以核桃青皮为原料,浸提法获得萜类,用光度计对常温保存和冷冻贮藏下的类胡萝卜素含量进行分析。结果显示,常温保存和冷冻贮藏下,核桃青皮中类胡萝卜素含量差异很大。其中,常温保存时核桃青皮中类胡萝卜素含量为0.8%;冷冻贮藏时核桃青皮中类胡萝卜素含量为1.4%。结果表明,冷冻状态更有利于核桃青皮中类胡萝卜素的保存。
Using green husk of Juglans regia L as raw material,extraction to obtain the terpenoids and analysis of content of carotenoid in the normal temperature and freezing storage by photometer were performed.The results showed that under normal temperature and freezing storage the contents of carotenoid of green husk of Juglans regia L varied greatly,0.06%and 0.14%respectively.The freezing storage is more conducive to the preservation of carotenoids in green husk of Juglans regia L.
