中文摘要: 利用顶空固相微萃取法,结合气相色谱-质谱联用技术对脯氨酸美拉德反应产物的挥发性成分进行分析,对SPME条件包括萃取头的选择、萃取温度和萃取时间进行优化。结果表明,最佳固相微萃取试验条件下(100 μm PDMS萃取头,80℃下萃取60 min),从脯氨酸美拉德反应物中共鉴定出76种挥发性成分,相对百分含量为74.42%,包括醛类3种(42.94%),杂环化合物15种(6.92%),酯类15种(9.29%),醇类14种(5.98%),烃类13种(3.91%),酮类 7种(2.74%),酸类 6种(1.87%),烯类 3种(0.77%)。就单一物质而言,5-(1-哌啶)-2-呋喃甲醛最高,为35.38%,其次是5-羟甲基糠醛7.04%、邻苯二甲酸乙酸异丁酯3.23%、庚酸酐1.83%、(Z)-9-十六碳烯酸甲酯1.66%、十六醇1.39%等。
Abstract:The volatile constituents of Proline Maillard Reaction Products were analyzed by Headspace Solid Phase Microextraction(HS-SPME)combined with Gas Chromatography-Mass Spectrometry(GC/MS).The SPME conditions included extraction head selection,extraction temperature and extraction time optimization were optimized.The results showed that the optimum extraction conditions were 100 μm PDMS extraction heads,80℃,and 60 min extraction.Under these conditions,76 volatile components were identified from Proline Maillard reaction,with a relative percentage of 74.42%,including 3 kinds of aldehydes(42.94%),15 kinds of heterocyclic compounds(6.92%),15 kinds of esters(9.29%),14 kinds of alcohols(5.98%),13 hydrocarbons(3.91%),7 kinds of ketones(2.74%),6 acids(1.87%),3 alkenes(0.77%).In the case of a single substance,Furan-2-carboxaldehyde,5-(1-piperidyl)-was 35.38% ,the highest,followed by 5-HMF 7.04%,Phthalic acid,hex-3-yl isobutyl ester 3.23%,Heptanoic acid,anhydride 1.83%,9-Hexadecenoic acid,methyl ester,(Z)-1.66%,1-Hexadecanol 1.39%,etc.
