为研究洞庭湖区河滩野生南荻嫩茎的营养价值和开发前景,以鲜样去壳冻藏和热烫后去壳冻藏的嫩茎为原料,分析测定其主要化学成分。结果表明:新鲜南荻嫩茎和热烫南荻嫩茎的水分含量分别为91.86%和89.32%、总糖含量分别为3.08%和3.72%、还原糖含量分别为1.10%和1.86%、蛋白质含量分别为2.90%和3.55%、总膳食纤维含量分别为31.81%和43.67%、总灰分含量分别为0.36%和0.33%,南荻嫩茎中富含15种氨基酸,含有钾、钠、钙、镁、锰、锌、铜、硒等元素,重金属铅、镉、铬未检出,汞和砷含量低于国标限量值。

This study was conceived to analyze the nutritional value and prospect of the tender stems of Triarrhena lutarioriparia growing on the beach of Dongting Lake. The fresh samples were peeled and separated into two portions: one was blanched before refrigerated storage, and the other was directly refrigerated. The two portions were tested for major chemical components. The results showed the fresh and blanched tender stems to contain 91.86% and 89.82% moisture, 3.08% and 3.72% total sugar, 1.10% and 1.86% reducing sugar, 2.90% and 3.55% protein, 31.81% and 43.67% total dietary fiber(dry basis), a...
