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).

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。

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^-1 of 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.
