摘要
为充分了解江苏省淮安市6种特色蔬菜的营养价值并进一步开发利用,采用国标方法对淮安蒲菜、紫芽青萝卜、红椒、黑芭菜、草莓、杨花萝卜共6种蔬果中基本营养物质、维生素和矿物质的含量进行测定,并对其中10种矿物元素进行主成分分析,建立矿物元素主成分方程,并进行综合评价。结果显示,6种蔬果中蛋白质、灰分、不溶性膳食纤维、Na、Ca、Mg、Fe、Zn含量最高的均为芭菜,维生素A含量最丰富的是紫芽青萝卜(579 mg/100 g),维生素C含量最丰富的是淮安红椒(1.4×10~2 mg/100 g),K、P、Mn含量最丰富的是蒲菜。主成分分析也表明,这6种蔬果按矿物元素含量综合分析排序为黑芭菜、蒲菜、杨花萝卜、草莓、红椒、紫芽青萝卜。可见,黑芭菜可作为补充Ca、Na、Mg、Fe、Zn,蒲菜可作为补充K、P、Mn,红椒可作为补充维生素C等元素的重要食物。
In order to fully understand the nutritional value of six characteristic vegetables and fruits in Huai'an City,Jiangsu Province,and to provide scientific basis for further rational development,the national standard method was used to determine the content of basic nutrients,vitamins and minerals in six vegetables and fruits,namely,Typha latifolia L.,Raphanus sativus,C.annuum var.Grossum,Brassica campestris L.,Fragaria×ananassa Duch.and Raphanus sativus L.,and the principal component analysis of 10 mineral elements was carried out to establish the principal component equation and comprehensively evaluate.The results showed that among the six vegetables,Brassica campestris L.had the highest content of protein,ash,insoluble dietary fiber,Na,Ca,Mg,Fe and Zn,Raphanus sativus had the highest vitamin A content(579mg/100 g),C.annuum var.Grossum had the highest vitamin C(1.4×102 mg/100 g),and the most abundant K,P,Mn content was Typha latifolia L..The principal component analysis also showed that the six kinds of vegetables and fruits were ranked as Brassica campestris L.,Typha latifolia L.,Raphanus sativus L.,Fragaria×ananassa Duch.,C.annuum var.Grossum and Raphanus sativus.It could be seen that Brassica campestris L.could be used as a supplement of Ca,Na,Mg,Fe and Zn,Typha latifolia L.could be used as a supplement of K,P and Mn,and C.annuum var.Grossum could be used as an important food to supplement vitamin C and other elements.
