摘要
采用水蒸汽蒸馏法提取出酥油中的风味物质,利用气相色谱-质谱联用技术对西藏酥油中的风味物质进行了分离、鉴定,共确定了34种化合物及其它们的相对含量。其中羧酸9种,酯11种,酮6种,醇2种,烯类化合物4种,苯胺类化合物和苯酚类化合物各1种。其中主要成分为己酸和辛酸,其相对含量分别为30.35%和33.22%。
The flavor bodies of Tibet Ghee was concentrated by water team distillation, then separated and identified by GC- MS. 34 components and their relative concentration have been identified. They were acids (9), esters ( 11 ), ketones (6), alcohols(2), alkene (4), aminobenzene compound ( 1 ) and phenylol ( 1 ). Hexanoic acid and octanoic acid were the main ingredients, their relative concentration respectively 30.35% and 33.22%.
