Progress and analysis of detection methods of milk quality

High-quality milk is the inevitable development direction of dairy industry in China,which makes detection methods of milk quality necessary.A preliminary evaluation is done on milk quality by detecting the sensory index firstly.Then a further judgment is made by obtaining its physicochemical and microbiological indexes. The sensory detection is the most direct and easiest methods to evaluate the quality of milk,and detection of physicochemical indexes is widely used methods including freshness and nutrition indicators,while detection of microbiological indexes is one of the important ways to reflect edible value of milk. These methods for determining milk quality have different merit or shortcoming on accuracy,operational process,analysis efficiency,cost,environmental protection,etc. In this paper,detection methods of milk quality were reviewed mainly focusing on three aspects,including sensation,physical and chemical properties,and microbial properties,in expection of providing dairy industry with theoretical basis.
