沉水植物苦草的营养成分分析与综合利用

Analysis of Nutrient Composition and Comprehensive Utilization of Submersed Aquatic Macrophytes(Vallisneria natans)

摘要: 沉水植物苦草的营养成分分析结果表明,其蛋白质含量为218.4 g.kg^-1,脂肪含量为51.4 g.kg^-1,多糖含量为37.6 g.kg^-1,灰分含量为265.7 g.kg^-1;氨基酸总量为147.6 g.kg^-1(色氨酸未测),必需氨基酸为55.0g.kg^-1;含有K、Ca、Cu、Fe、Zn、Mn、Na、A l、Ba等多种矿质元素,其中K、Ca、Fe、Na含量分别高达60.5、10.9、16.3、12.7 g.kg^-1。可见苦草是一种优质的营养资源,具有很高的开发价值。在此基础上,进一步探讨了苦草的资源化利用方式和应用前景。

Abstract: Nutrient composition of Vallisneria natans was analyzed.Results show that V.natans contained 218.4 g·kg^-1 of protein,51.4 g·kg^-1 of crude fat,37.6 g·kg^-1 of polysaccharides,265.7 g·kg^-1of ash;and 147.6 g·kg^-1 of total amino acids,55.0 g·kg^-1 of essential amino acid;and a number of mineral elements,such as 60.5 g·kg^-1 of K,10.9 g·kg^-1 of Ca,16.3 g·kg^-1 of Fe,12.7 g·kg^-1 of Na.It is quite obvious that V.natans is a quality nutrient resource and highly worth exploiting.On such a basis,further efforts have been made to explore ways and prospects of comprehensive utilization of V.natans.
