摘　　要：研究原料乳中硫氰化物掺假物质定性检测的方法，通过向原料乳中人为添加定量硫氰化物，在酸溶液中硫氰酸根与三价铁离子反应生成可溶于水及乙醚的血红色化合物，根据样品中硫氰酸根含量的多少，所显示的颜色不同。通过颜色反应判定原料乳中是否添加硫氰化物掺假物质。实验结果表明，该方法用于检测原料乳中硫氰化物质量分数在0．005％以上，具有良好的可操作性，同时方法操作简单，结果便于观察，适用于乳制品企业进行原料乳质量验收检验。The raw milk sulfur in cyanide adulterate material qualitative detection method, through to the raw milk which artificial add quantitative sulfur cyanide, in acid solution thiocyanic acid root and ferric iron ion reaction generate soluble in water and ethyl ether sanguine compound, according to samples thiocyanic acid root content of how many, shows different colors. Through the color reaction determine whether raw milk add sulfur cyanide adulterate material. Through the experiment discovered, and the results show that this method is mainly used in the detection of raw milk sulfur in cyanide mass fraction in more than 0.005% have good maneuverability, and at the same time, methods the operation is simple, the result for observation, suitable for dairy products enterprise to carry out the raw milk quality acrceptance inspection.
