This paper was aimed to set a simple and highly-efficient method for lactose adulteration detection in raw milk. After pretreatment using trichloroacetic acid as precipitant,at 589.30-589.44nm,the optical rotation was measured by polarimeter to create standard curve about standard lactose solution. So as to establish a polarimetric method for quantitative detection of the lactose adulteration in raw milk based on standard curve. The correlation coefficent（R^2） of this regression equation acquired in our study was equivalent to 0.9993;the aver...
