雷竹笋营养成分的分析测定

以湖北咸宁崇阳县不同加工处理过的雷竹笋为试材,测定其营养成分(可溶性蛋白质、可溶性糖、淀粉、粗脂肪、粗纤维等)的含量。结果表明:每100 g保鲜雷竹笋中可溶性糖含量为1.65 g,粗纤维含量为0.45 g,粗脂肪含量为0.58 g,淀粉含量为2.56 g,可溶性蛋白质含量为2.95 g;每100 g干雷竹笋中可溶性糖含量为1.35 g,粗纤维含量为0.60 g,粗脂肪含量为0.44 g,淀粉含量为1.72 g,可溶性蛋白质含量为2.26 g。由此可见保鲜雷竹笋营养成分的含量相对高于干雷竹笋,总的来说,雷竹笋是一种粗脂肪含量较少而蛋白质含量较高的森林蔬菜和健美食品。

Analysis and Determination of the Nutritive Composition in the Phyllostachy spraecox shoot

The different processed Phyllostachy spraecox shoots from Chongyang county of Xianning Region in Hubei province were used as the material and its nutrition ingredient(soluble protein,soluble sugar,starch,crude fat,crude fiber and so on) was tested.The result showed that the content of soluble sugar in fresh Phyllostachy spraecox shoots's in every 100 g was 1.65 g,the content of crude fiber was 0.45 g,the content of crude fat was 0.58 g,the content of starch was 2.56 g and the content of soluble protein was 2.95 g.The content of soluble sugar in dried Phyllostachy spraecox shoots in every 100 g was 1.35 g,the content of rude fiber was 0.60 g,the content of crude fat was 0.44 g,the content of starch was 1.72 g and the content of soluble protein was 2.26 g.It can be seen from above that the nutrition ingredient content of fresh Phyllostachy spraecox shoot was higher than the dried Phyllostachy spraecox shoot.In a word the Phyllostachy spraecox shoot was a kind of shoot which had little crude fat but the high protein content.It was a good forest vegetable and healthy food.
