摘要
本研究以榛子油为原料,对其挥发性成分、含水量以及体外抗氧化活性进行研究.以不同地区的榛子为研究对象,利用顶空固相微萃取法结合气相色谱-质谱联用和低场核磁共振技术研究了不同地区的榛子油挥发性成分和含水量.同时,利用分光光度计法对不同榛子油的抗氧化能力进行了检测.各地榛子含水量基本不超过2%,不同产地榛子油挥发性成分中共鉴定出7 类37 种化合物.在体外抗氧化实验中,大连榛子表现出最强的抗氧化能力.
Abstract
This study investigates the volatile components,water content,and in vitro antioxidant activity of hazelnut oil.Hazelnuts from different regions were selected for the study.The volatile components and water content of the hazelnut oils were analyzed using headspace solid-phase microextraction combined with gas chromatography-mass spectrometry and low-field nuclear magnetic resonance techniques.Ad-ditionally,the antioxidant capacity of the different hazelnut oils was measured using a spectrophotometric method.The water content of the hazelnuts from various regions was generally below 2%.A total of 37 com-pounds belonging to 7 categories of volatile components were identified in the hazelnut oils from different re-gions.In the in vitro antioxidant tests,the hazelnuts from Dalian exhibited the strongest antioxidant activity.
