个旧地区冬春两季绿芦笋营养品质分析与比较

Analysis and Comparison of Nutritional Quality from Winter and Spring Asparagus in Gejiu Area

对个旧地区8个芦笋种植点的冬春两季芦笋中的蛋白质、还原糖、维生素C、黄酮、有机酸含量进行了测定分析和比较。结果表明:春季芦笋的蛋白质、维生素C、黄酮、有机酸、还原糖含量均高于冬季;芦笋中蛋白质、还原糖、维生素C、黄酮含量受季节影响较小,有机酸含量受季节影响较大。用模糊数学的隶属函数法对所有样品的综合营养品质进行了评价,表明春季芦笋样品的综合营养品质隶属函数值均大于冬季的,个旧地区春季芦笋的品质优于冬季芦笋。
