摘　　要：为实现掺假鳕鱼肉松的快速检测,采用气相色谱-质谱联用技术,以掺假鸡肉松为例,按照不同比例将鸡肉松混入鳕鱼肉松中制备成掺假肉松,结合主成分分析(PCA)、差异代谢物热图分析(HCA)等多元统计分析方法对样品进行检测。气相色谱-质谱法共检测到36种挥发性化合物,硫酸二甲酯、2-丙基-1-庚醇、2-乙基呋喃、八甲基环四硅氧烷、4-甲基-3-戊烯醛、2,3-二氯丁酸、L-亮氨酸甲酯、4-甲基辛烷、亚硝酸异戊酯等被认为在区分不同样品中起重要作用,试验为鳕鱼肉松掺假提供理论依据。In order to realize the rapid detection of adulterated cod meat floss,the adulterated chicken meat floss was mixed into cod meat floss in different proportions to produce adulterated meat floss,and the samples were detected by multivariate statistical analysis methods such as principal component analysis(PCA)and differential metabolite heat map analysis(HCA).A total of 36 volatile compounds were detected by gas chromatogen-mass spectrometry.Dimethyl sulfate,2-propyl-1-heptanol,2-ethylfuran,octamethylcyclotetrasiloxane,4-methyl-3-pentenal,2,3-dichlorobutyric acid,L-leucine methyl ester,4-methyl-octane,isoamyl nitrite,etc.,were considered to play an important role in distinguishing different samples.This study could provide theoretical basis for the adulteration of cod floss.
