广西常见蔬菜营养成分分析与评价

Analysis on Nutritional Component of Familiar Vegetables in Guangxi Province

目的:对广西常见蔬菜的营养成分分析测定,为人们日常的膳食结构提供科学依据。方法:按照国家标准方法对11种蔬菜的灰分、蛋白质、膳食纤维、维生素、矿物质含量等进行测定。结果:11种蔬菜可食部分的营养成分差异很大,但都富含各种营养元素。如白花菜蛋白质含量最高3.75g/100g,芥菜维生素C含量最高为40.66mg/100g,而菜心、枸杞叶、土豆、芥菜、空心菜、一点红等富含各种矿质元素。结论:所测定的11种蔬菜中的营养成分不能完全满足人体的日常需求。建立广西食物营养成分表,将有助于蔬菜的深度研究、合理开发与科学膳食。
