The objective of the study was to develop optimum Headspace-Solid Phase Microextraction (HS-SPME) conditions for determining volatile compounds of margarine. The effects of fiber type, extraction temperature, extraction time on extraction rates of 2,3 butandione, dimethyl disulfide, nonanal, butanoic acid, hexanoic acid, octanoic acid, γ-nonalactone, δ-decalactone, total area and number of volatile compounds were investigated. A response surface methodology was applied using three independent variables such as fiber type, extraction temperature and extraction time. The fiber type, extraction temperature and extraction time were arranged with Box-Behnken design. The results shows that extraction temperature and extraction time affect both total area and number of volatile compounds but fiber type effect total area of volatile compounds. The optimum HS-SPME conditions were determined as 47.54 °C extraction temperature and 33.63 min extraction time using DVB/CAR/PDMS fiber type.
本研究的目的是开发用于测定人造黄油挥发性化合物的最佳顶空固相微萃取（HS-SPME）条件。研究了纤维类型、萃取温度、萃取时间对2,3-丁二酮、二甲基二硫醚、壬醛、丁酸、己酸、辛酸、γ-壬内酯、δ-癸内酯、挥发性化合物总面积和数量萃取率的影响。采用响应面法，使用纤维类型、萃取温度和萃取时间三个独立变量。纤维类型、萃取温度和萃取时间采用Box-Behnken设计进行安排。结果表明，萃取温度和萃取时间对挥发性化合物的总面积和数量均有影响，但纤维类型只影响挥发性化合物的总面积。使用DVB/CAR/PDMS纤维类型时，确定的最佳HS-SPME条件为萃取温度47.54°C和萃取时间33.63分钟。
