摘要
为分析研究八月瓜果实的营养价值,本文用火焰原子吸收光谱法、液相色谱法、荧光分光光度法等实验方法对八月瓜果皮、果肉和种子中营养物质成分进行检测分析。基于检测分析可知,八月瓜果实具有很高的营养价值。其中,八月瓜果皮含有锰、钾矿物质营养成分,含量分别为0.645、342 mg/100 g;八月瓜果皮总氨基酸含量为0.313 mg/100 g,含15种氨基酸,其中必需氨基酸7种,必需氨基酸比重达到WHO/FAO提出理想蛋白质条件,必需氨基酸含量不及果肉均衡,营养价值比果肉低;含有少量的维生素E、果胶、蛋白质和脂肪。八月瓜种子含有多种矿物质营养成分,即含钾、磷、钙、铁矿物质营养成分,含量分别为586、180、191、2.85 mg/100 g;八月瓜种子富含多种矿物质营养成分,即富含锰、铜、镁矿物质营养成分,含量分别为:4.63、1.3、157 mg/100 g;脂肪酸含量为2.662 g/100 g,不饱和酸含量比重为76%。八月瓜果肉含有铜矿质营养成分,含量为0.25 mg/100 g;富含锰矿物质营养成分,含量为7.51 mg/100 g;八月瓜果肉总氨基酸量含量为0.419 mg/100 g,含16种氨基酸,其中必需氨基酸8种,必需氨基酸比重达到WHO/FAO提出理想蛋白质条件,必需氨基酸含量均衡,营养价值高;含有少量的维生素、脂肪、蛋白质和黄酮。本文可为八月瓜果的开发利用提供理论支持和技术指导,推动八月瓜理论研究进程。
In order to analyze and evaluate the nutritional value of Akebia trifoliata fruit,Flame Atomic Absorption Spectrometry,Liquid Chromatography,Fluorescence Spectrophotometry and other experimental methods was used to detect and analyze the nutritional components in the peel,pulp and seed of Akebia trifoliata.Based on the detection and analysis,it could be seen that Akebia trifoliata fruit had high nutritional value.Among them:The peel of Akebia trifoliata contains mineral nutrients of Mn and K,the contents of Mn and K were 0.645 and 342 mg/100 g respectively.The total amino acid content in the peel of Akebia trifoliata was 0.313 mg/100 g,containing 15 kinds of amino acids,including 7 kinds of essential amino acids.The proportion of essential amino acids reached the ideal protein conditions proposed by WHO/FAO.The content of essential amino acids was less than that of pulp,and the nutritional value was lower than that of pulp.It contained a small amount of vitamin E,pectin,protein and fat.The seed of Akebia trifoliate contained many mineral nutrients,including K,P,Ca and Fe,with the contents of 586,180,191 and 2.85 mg/100 g,respectively.The seed of Akebia trifoliata was rich in many mineral nutrients,including Mn,Cu and Mg,with the contents of 4.63,1.3 and 157 mg/100 g,respectively.The fatty acid content was 2.662 g/100 g,and the proportion of unsaturated acid was 76%.The pulp of Akebia trifoliate contains Cu mineral nutrients and the content was 0.25 mg/100 g,was rich in Mn mineral nutrients and the content was 7.51 mg/100 g.The total amino acid content of Akebia trifoliata was 0.419 mg/100 g,containing 16 kinds of amino acids,including 8 kinds of essential amino acids.The proportion of essential amino acids reached the ideal protein conditions proposed by WHO/FAO,the content of essential amino acids was balanced and the nutritional value was high small amounts of vitamins,fats,proteins and flavonoids.This paper can provide theoretical support and technical guidance for the development and utilization of Akebia trifoliata,and promote the theoretical research process of Akebia trifoliata.
