桂北中高海拔丘陵山区罗汉果营养成分分析

Analysis the nutrient compositions of Siraitia grosvenorii in the hilly region at north Guangxi

为了探索桂北中高海拔丘陵山区龙胜各族自治县乐江镇宝赠村罗汉果(Siraitia grosvenorii)种植基地果实的营养成分及其品质,分别测定了灰分、总糖、蛋白质、粗纤维、脂肪、维生素C(VC)、维生素E(VE)和氨基酸含量,并将其与永福、湘西产的罗汉果进行了比较研究。结果表明,龙胜产罗汉果灰分含量为(7.59±1.05)%,总糖含量为(59.99±6.33)%,蛋白质含量为(21.26±1.68)%,粗纤维含量为(63.25±5.01)%,脂肪含量为(0.09±0.02)%,VC含量为(38.00±3.06)mg/100 g,VE含量为(0.61±0.02)mg/100 g;龙胜产罗汉果的蛋白质、VE和脂肪含量比永福产罗汉果分别高7.37%、3.39%和12.50%,总糖、粗纤维和灰分含量龙胜产罗汉果分别为59.99%、63.25%和7.59%,略低于永福产罗汉果66.70%、69.16%和8.72%;龙胜产罗汉果灰分、总糖、蛋白质、粗纤维和VC含量分别是湘西产罗汉果相关成分含量最大值的1.61、1.99、2.46、1.38和4.85倍;龙胜产罗汉果含有人体所需的17种氨基酸,氨基酸总量为8.20%,其中人体必需氨基酸含有7种,占氨基酸总量为31%,其氨基酸组成与永福产的罗汉果基本一致,只是含量上略有差异。桂北丘陵山区龙胜产罗汉果有丰富的营养成分,蛋白质含量、氨基酸和VC等较高,品质优异,表现出较高的营养价值,适宜扩大和规模化种植。

The nutrient compositions extracted from Siraitia grosvenorii in the middle and high altitude hilly region at northern Guangxi(Longsheng autonomous county,Guilin city)were analyzed and compared with Yongfu and Xiangxi county,contents of ash,total sugar,protein,crude fiber,fat,vitamin C(VC),vitamin E(VE)and amino acid were determined.Results showed that the con⁃tents of ash,total sugar,protein,crude fiber,fat,VC and VE were(7.59±1.05)%,(59.99±6.33)%,(21.26±1.68)%,(63.25±5.01)%,(0.09±0.02)%,(38.00±3.06)mg/100 g and(0.61±0.02)mg/100 g.Contents of protein,VE and fat from Siraitia grosveno⁃rii in Longsheng were higher than that of Yongfu with 7.37%,3.39%and 12.50%,the contents of total sugar,crude fiber and ash from Siraitia grosvenorii in Longsheng were 59.99%,63.25%and 7.59%which were lower than Yongfu with 66.70%,69.16%and 8.72%.The contents of ash,total sugar,protein,crude fiber and VC in Siraitia grosvenorii of Longsheng were 1.61,1.99,2.46,1.38 and 4.85 times of the maximum contents of related components in Xiangxi county.There were 17 kinds of amino acids in Longsheng Siraitia grosvenorii,contents of total amino acids were 8.20%,7 kinds of human body essential amino acids were 31%.There was no signifi⁃cant difference in contents of amino acids in Siraitia grosvenorii between Longsheng and Yongfu.Siraitia grosvenorii is rich in nutrient,which has high protein content,amino acid and VC.It shows higher nutritional value and is suitable for expanding and large-scale planting in the middle and high altitude hilly region at northern Guangxi.
