SDE/GC-MS分析无籽刺梨酒渣挥发性成分

摘要

Volatile flavor components of Rosa sterilis dregs was analyzed by SDE/GC-MS,72 compounds were identified.The main component is Ethyl stearate (15.03％),Ethyl Heptadecanoate (6.86％),and 2-methyl butanol (6.30％).There are 13 alcohol compounds such as 2-methylbutanol (6.30％),isopentanol (3.85％),2-Hydroxyheptane (3.70％);nine aldehydes and ketones compounds including β-cyclohomocitral (2.67％),phenylacetaldehyde (0.58％),furfural (0.29％);17 kinds of acid compounds including octanoic acid (3.76％),octadecanoic acid (1.84％),isovaleric acid (0.37％),and there are also 33 Phenolic compounds,esters compounds and alkene compounds.The study provides a reference for further study and the usage of Rosa sterilis dregs.%采用SDE/GC-MS法分析无籽刺梨酒渣挥发性香气成分,结合保留指数定性确定无籽刺梨酒渣成分,共分析鉴定出72种成分,无籽刺梨酒渣化学成分中硬脂酸乙酯(15.03％)、十七酸乙酯(6.86％)和2-甲基丁醇(6.30％)等,是构成无籽刺梨酒渣的基础成分.其中,醇类物质有2-甲基丁醇(6.30％)、异戊醇(3.85％)和2-庚醇(3.70％)等13种化合物;醛酮类物质有β-环柠檬醛(2.67％)、苯乙醛(0.58％)和糠醛(0.29％)等9种化合物.酸类物质有辛酸(3.76％)、十八烷酸(1.84％)和异戊酸(0.37％)等17种化合物.无籽刺梨酒渣中还含有酚类、酯类和烯类等33种化合物.本文意在初步探讨无籽刺梨酒渣挥发性成分,为开废渣的替代香料价值提供数据支持.
