摘要
为了比较安顺普定地区人工种植的刺梨与无籽刺梨基本营养成分及香气物质的差异,以当地种植的刺梨"贵农五号"和无籽刺梨"安顺金刺梨"为原料,测定其果实性状、主要营养成分以及香气物质。结果表明:两种果实大小、形状、重量、色泽等有明显区别;无籽刺梨的总糖、还原糖、总酸、总黄酮含量明显高于刺梨,而VC、SOD则低于刺梨;刺梨检出41种风味物质,主要有柠檬烯(28.675%)、辛酸乙酯(15.095%)、正己酸乙酯(9.897%)、β-花柏烯(5.758%)、愈创木烯(5.447%)、β-罗勒烯(5.270%)、乙酸叶醇酯(4.067%)等。无籽刺梨检出40种风味物质,主要有β-罗勒烯(14.840%)、乙酸叶醇酯(11.957%)、β-花柏烯(8.300%)、顺式-3-己烯醇(7.282%)、愈创木烯(7.261%)、茶香螺烷(7.123%)等,两者检出21种相同物质。
Characteristics nutrition components and aroma compounds were determined to compare the difference of the basic ingredients and volatile aroma compounds between the ＂Guinong five＂Rosa roxburghii Tratt and＂Anshun＂Rosa sterilis D.shi of Puding district of Anshun city.Results indicated that significant differences of size,shape,weight and color in the two fruits. For nutrient contents,total sugar,reducing sugar,total acidity and flavonoids in Rosa sterilis D.shi were higher than Rosa roxburghii Tratt,while VCand SOD were on the opposite.For aroma compounds,41 aroma compounds were found in Rosa roxburghii Tratt including limonene（ 28.675%）,ethyl caprylate（ 15.095%）,ethyl caproate（ 9.897%）,β- Chamigrene（ 5.758%）,guaiene（ 5.447%）,β- Ocimene（ 5.270%）,cis- 3- hexenolacetate（ 4.067%） and so on.40 aroma compounds were found in Rosa sterilis D.shi including β- Ocimene（ 14.840%）,cis- 3- hexenolacetate（ 11.957%）,β- Chamigrene（ 8.300%）,3- hexen- 1- ol（ 7.282%）,guaiene（ 7.261%）,2,6,10,10- Tetramethyl-1- oxa- spiro[4.5]dec-6- ene（ 7.123%） and so on.There were some differences between the two fruits while they still had the same 21 aroma compounds.
