摘要
为探讨不同品种的营养品质,筛选马铃薯主食化加工的区域适宜品种,分别采用减压干燥法、旋光仪法、3,5-二硝基水杨酸(DNS)比色法、双缩脲法、高效液相色谱法(HPLC)、电感耦合等离子体-发射光谱法(ICP-OES)等检测方法,对定西市引进试种的10个品种马铃薯样品的干物质、淀粉、还原糖、蛋白质、VC等一般营养成分及矿物元素进行了分析测定。结果表明,10个马铃薯品种中,AGRICO-5淀粉含量和干物质含量明显高于其他9个品种,蛋白质、VC及钾、镁、钙和铁等矿质含量均处于较高水平,与对照品种大西洋接近,而还原糖含量显著低于其他9个品种及对照,作为主食化品种具有较好的加工品质,符合营养要求,适宜在该地进行区域推广。
In order to research nutritional quality of different varieties potato, the suitable potato cultivars as the staple food develepment were introduced. The dry matter,starch,reduceing sugar,protein,VC and mineral elements of 10 diferent varieties potato from domestic were compared by decompression drying method,rotator method,3,5-dinitrosalicylic acid(DNS)colorimetry,double condensation urea method,high performance liquid chromatography(HPLC), inductively coupled plasma-emission spectrometry(ICP-OES) and other detection methods. The results showed that the starch and dry matter content of AGRICO-5 in 10 potato varieties were significantly higher than those of 9 other varieties,and protein,VC,potassium,magnesium,calcium and iron was at a high level,which was close to that of the control sample Atlantic Ocean. The content of reducing sugar is significantly lower than that of other 9 varieties and controls. As a staple food,it had a good processing quality and met the nutritional requirements,and was suitable for local promotion.
