江苏不同产地芡实营养成分比较分析

Comparative Analysis on Nutrient Component of <i>Euryale ferox</i> Salisb. from Different Growing Regions in Jiangsu

芡实是一种特色水生蔬菜,俗称鸡头米,具有很高的营养保健功能。近年来,原产苏州的苏芡在江苏省内大力推广种植。通过对产自苏州、金湖、泗阳的苏芡芡米进行营养成分的比较分析,旨在为苏芡产地的合理选择、产品的合理开发提供一定的理论参考。结果表明:原产地苏州的芡米中蛋白质、锌及VC含量显著高于其他产地,水分、钙、VB2等其他营养成分含量也较高,综合表现较好。金湖的芡米中矿质元素钙、镁、锰含量高,矿物质含量丰富。泗阳的芡米中总糖含量最高,水分和灰分含量最低,镁、锌、铁、锰等矿质元素及维生素含量均处于中间水平。可见不同产地的芡米各有突出的营养成分,可用于针对性地开发不同类型的功能性食品。

Qianshi, referred to as Gordon Nut, is the kernel seed of Euryale ferox Salisb. It is a special aquatic vegetable, which has highly nutritional and healthy protection value, also named Jitou (chicken head). In recent years, South Euryale ferox (Su Qian), which is originally cultivated in the suburban district of Suzhou, is introduced widely in Jiangsu Province. Making comparative analysis on nutrient components of Su Qian from Suzhou, Jinhu and Siyang, this study was to provide theoretical references for choosing growing regions and developing products appropriately. The result showed: Gordon Euryale Seed from Suzhou has highest Protein, Zn and Vc contents, which was significantly higher than that of the others. It’s also with high content in other nutrients such as moisture, Ca and VB2. So the comprehensive performance is better. Gordon Euryale Seed from Jinhu is abundant in mineral elements including Ca, Mg and Mn. Gordon Euryale Seed from Siyang contains more sugar and less moisture and ash than others. The contents of Mg, Zn, Fe, Mn and Vitamins are in the middle. In conclusion, Gordon Euryale Seed from different growing regions has different nutrient components so that it can be applied to different functional foods.
