摘要：以定西地区9个主栽马铃薯品种为研究对象,对淀粉和还原糖含量分别采用旋光法和3,5-二硝基水杨酸比色法进行了分析测定。结果表明,不同品种的淀粉和还原糖含量差异很大,由于马铃薯所含成分的不同而有不同的用途,可将新大坪分为菜用型和淀粉加工型品种,陇薯3号、陇薯5号和陇薯6号分为淀粉加工型品种,定薯1号和陇薯4号分为淀粉加工型和薯条薯片加工型品种,黑美人为菜用型品种,大西洋和夏波蒂为薯条薯片加工型品种。
The paper, which uses the nine varieties of potatoes produced in Dingxi as objects of study, does a survey on the content of reducing sugar and starch in them respectively by the method of polarimetry and 3,5-dinitrosalicylic acid reagent colorimetry. The result shows the contents of reducing sugar and starch varies greatly in different types of potatoes. According to the differences in element and function, Xindaping can be divided into vegetable-based type and starch-possessing type, Longshu 3,5,6 falls into the type of starch producing, Dingshu 1 and Longshu 4 can be divided into starch producing type and chips-and-shreds producing types, Heimeiren belongs to vegetable-based type, Daxiyang and Xiabodi belong to chips- and-shreds producing type.
