【摘要】：目的:优选核桃仁挥发性芳香物质成分的固相微萃取条件,并利用GC-MS法对比分析新疆产新鲜核桃仁与酸败核桃仁样品的芳香物质成分。方法:采用单因素试验和正交试验设计优化固相微萃取条件,利用GC-MS分析对比新鲜核桃仁与酸败核桃仁的成分。结果:优选得到的固相微萃取条件为:采用75μm CAR/PDMS萃取头,取样量为2.0 g,萃取温度为60℃,萃取时间为30 min。分别从新鲜核桃仁和酸败核桃仁中分离鉴定了28种和33种挥发性成分。结论:该实验优选的萃取方法简单、可行,可用于核桃仁中挥发性芳香物质的萃取。
[Abstract]:Objective: to optimize the conditions of solid-phase microextraction of volatile aromatic compounds from walnut kernel. GC-MS method was used to compare and analyze the aromatic components of fresh walnut kernel and rancid walnut kernel samples from Xinjiang. Methods: single factor test and orthogonal design were used to optimize the conditions of SPME. The composition of fresh walnut kernel and rancid walnut kernel were analyzed by GC-MS. Results: the optimum conditions of solid-phase microextraction were as follows: the extraction head was 75 渭 m CAR/PDMS, the sample quantity was 2.0 g, the extraction temperature was 60 鈩，
