沉水植物苦草的营养成分分析与综合利用

Abstract

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.
