牛奶比重计主要用于牛奶 马奶  羊奶 豆浆的密度的测量。

奶中加水检出法:  鲜奶中加水则稀薄,比重常低于1.028,这种奶有掺水的可能。掺水量可用下公式计算: 掺水的百分数=(正常奶的比重-被检奶的比重)/正常奶的比重*100 例如:正常奶比重1.031,被检奶比重1.027 掺水量百分比=(1.031-1.027)/1.031*100=13% 奶中加淀粉的检出法:  牛奶加水后变稀薄,有人便加入淀粉使奶变得比重接近正常奶。检验方法:取被检奶5毫升放入试管,加入碘水2-3滴,如有淀粉则有蓝色出现。(碘水用1克碘化钾溶于少量蒸馏水中,在此溶液中溶解0.5克结晶碘,再移入100毫升水中) 奶中加豆浆的检出法:  取被检奶5毫升,放入试管中,加入乙醇与乙醚混合液3毫升,再加入28%氢氧化钾溶液2毫升,在5--10分钟内观察颜色的变化,如呈微黄色则有豆浆,其所含的皂角素与氢氧化钾作用。 牛奶是否脱脂的检出法:  牛奶脱脂后变得稀薄略带蓝色,验时乳脂率低,而奶的比重升高,总的干物质含量降低。
