DOI:10.13386/j.issn1002-0306.2011.06.055 恽卓婷,廖鲜艳,翁新楚* (上海大学生命科学院,上海200444) 摘要:在对茶叶籽及油茶籽的外观、含仁率、含油率等进行测定的基础上,对茶叶籽油及油茶籽油的理化性质及脂肪 酸组成进行了分析。结果表明,茶叶籽及油茶籽外观相差较大,茶叶籽油与油茶籽油在折光指数、酸值、碘值和皂化值 等理化性质上较接近。脂肪酸组成上,油酸、亚油酸、棕榈酸为茶叶籽油及油茶籽油中含量最多的三种脂肪酸,油酸含 量分别为5213%和7367%,亚油酸2432%和1109%,棕榈酸1736%和1063%。茶叶籽油和油茶籽油的单不饱和 脂肪酸含量分别为5412%和7578%,多不饱和脂肪酸含量为2455%和1139%。茶叶籽含油率为1988%,茶叶籽油 潜在年产量可达15余万t。其必需脂肪酸含量是油茶籽油的215倍;不皂化物含量为077%,比油茶籽油高出22%; 茶叶籽油脂肪酸比例均衡,适于人体的吸收,具有开发应用的潜力。 关键词:茶叶籽油,油茶籽油,理化性质,脂肪酸 Comparisonofphysicochemicalpropertiesandfattyacidscompositionof teaseedoilandcamelliaoleiferaseedoil YUNZhuo-ting,LIAOXian-yan,WENGXin-chu* (DepartmentofFoodScienceandEngineering,SchoolofLifeSciences,ShanghaiUniversity,Shanghai200444,China) Abstract:Physicochemicalpropertiesandfattyacidscompositionofteaseedoil(camelliasinensisOKtze)andcamellia oleiferaseedoil(CamelliaoleiferaAbel)werestudiedTheappearance,thekernelyieldandoilyieldofthesetwoseeds werealsodeterminedTheresultsindicatedthatphysicochemicalpropertiesofthesetwooilsweresimilarbutthe appearanceoftwoseedswasdifferentThemajorfattyacidsofteaseedoilandcamelliaoleiferaseedoilwereoleic acid,linoleicacidandpalmiticacidThecontentofmonounsaturatedfattyacidsofteaseedoilandcamelliaoleifera seedoilwas5412%,7578%,respectivelyThepolyunsaturatedfattyacidscontentofthesetwooilswas2455%, 1139%,respectivelyTheoilcontentofteaseedwas1988%Thepotentialannualyieldofteaseedoilwouldreach15 milliontonsThecontentofessentialfattyacidofteaseedoilwas215timesmorethancamelliaoleiferaseedoil,while thecontentofunsaponifiablematterofteaseedoil(077%)was22%morethancamelliaoleiferaseedoilThefatty acidsratioofteaseedoilwasbalancesothatthisoilwasbeneficialforhumanhealthTherefore,teaseedoilhasa considerablepotentialforproductionanddevelopment Keywords:teaseedoil;camelliaoleiferaseedoil;physicochemicalproperties;fattyacids 中图分类号:TS2251+6文献标识码:A文章编号:1002-0306(2011)06-0136-03 茶叶籽是山茶科植物茶(CamelliaSinensis油茶树是同目、同科、同属、不同种的植物[3],从茶叶 OKtze)的果实,即茶叶树的果实,为茶叶生产的副
