摘要
【目的】研究湖南省通道县黑老虎常见栽培品系果肉果汁中主要营养成分及含量的变异情况,增进对黑老虎各品系特性的了解,为黑老虎水果型优良种质的筛选及推广应用提供科学依据。【方法】以10个黑老虎品系为研究对象,按照相关国家标准和行业标准,分别测定其果肉果汁中灰分、可溶性固形物、蛋白质、总糖、还原糖、总酸、维生素C和17种氨基酸等营养物质的含量,并采用单因素方差分析法比较分析其基本营养成分和氨基酸的组成及含量差异,采用相关分析法分析主要营养成分间的相关性,应用主成分分析法对10个黑老虎品系果肉果汁的营养品质进行综合评价。【结果】10个品系间果肉果汁中灰分、蛋白质、总糖、还原糖、总酸、维生素C、可溶性固形物和17种氨基酸的含量差异均极显著(P<0.01)。蛋白质含量,TD41的显著最高,其次为TD44的,两者均超过10 mg·g-1;TD43、TD41的总糖和还原糖含量均在35 mg·g-1以上,均显著高于其他品系的;总酸和维生素C含量分别以TD51和TD43的为最高;TD43、TD50和TD58的可溶性固形物含量均接近80 mg·g-1,均显著高于其他品系的。必需氨基酸中,异亮氨酸、亮氨酸、蛋氨酸、苏氨酸、缬氨酸的含量均以TD40的为最高,赖氨酸、苯丙氨酸、色氨酸的含量分别以TD41、TD44、TD54的为最高;儿童必需氨基酸中,精氨酸和组氨酸的含量均以TD40的为最高;非必需氨基酸中,谷氨酸、甘氨酸、丝氨酸的含量均以TD40的为最高,丙氨酸和天冬氨酸的含量均以TD54的为最高,脯氨酸和酪氨酸的含量分别以TD43和TD44的为最高。氨基酸总含量、必需氨基酸含量、儿童必需氨基酸含量、非必需氨基酸含量,TD40的均最高,其次均为TD41的。从变异系数分析,黑老虎各个品系之间,蛋白质含量的变异系数最大,其次分别是精氨酸、色氨酸和脯氨酸含量的变异系数(均超过40%),显�
【Objective】The variations of main nutritional components and their contents in fruit pulp and juice were investigated among commonly planted clones of Kadsura coccinea in Tongdao County,Hunan province,so as to increase understanding on properties of these clones,and to provide scientific evidences for selection and application of elite fruit-purposed germplasm.【Method】The contents of ash,protein,total sugar,reducing sugar,total acid,vitamin C,soluble solid,and 17 amino acids were measured for 10 K.coccinea clones according to relevant national and industrial standards,and differences in these basic nutrient,amino acid composition and contents were assessed by one-way variance analysis among these clones,and the relationship between main nutritional index was revealed by correlation analysis,and comprehensive evaluation was further carried out on the basis of principal component analysis.【Result】The significant differences were observed in contents of ash,protein,total sugar,reducing sugar,total acid,vitamin C,total soluble solid and 17 amino acid among 10 clones.Among these clones,the protein content was the highest significantly for clone TD41,followed by that for TD44,both were above 10 mg·g-1;the contents of total sugar and reducing sugar of clones TD43 and TD41 were above 35 mg·g-1,which were significantly higher than those of other clones;the contents of total acid and vitamin C were the highest in clone TD51 and TD43,respectively;and the contents of total soluble solid in clones TD43,TD50 and TD58 were near 80 mg·g-1,which were higher significantly than those in other clones.Among the essential amino acids for human(EAA),isoleucine,leucine,methionine,threonine and valine showed the highest significantly contents for clone TD40,lysine,phenylalanine and tryptophan for clones TD41,TD44 and TD54,respectively;for essential amino acids for child(CEAA),contents of arginine,histidine were the highest in clone TD40;among the non-essential amino acids for human(NAA),glutamic acid,glycine and serine sho
