The invention discloses a milk quality detecting device and method. The detecting method comprises the following steps: first, selecting three carrier gasses to detect volatile gases generated in n milk samples to obtain n w1 associated with the milk content of milk powder, then constituting points (w1, E) through w1 and the associated milk content E of the milk powder, fitting a detection model according to n points (w1, E) and calculating fitting precision R; selecting a milk quality forecasting model; and calculating the milk powder content E of milk K through a computer by virtue of the milk quality forecasting model and then calculating the milk powder content. The milk quality detecting device and method disclosed by the invention have the characteristics of capability of quickly detecting the milk powder content in the detected milk sample and high accuracy and reliability of detection.
Description
technical field [0001] The invention relates to the field of dairy product quality detection, in particular to a milk quality detection device and a detection method that can quickly and accurately detect the content of milk powder in milk. Background technique [0002] Usually, physical and chemical testing methods, instrumental analysis methods and principal component analysis methods are used to detect milk quality; however, physical and chemical testing methods and instrumental analysis methods have disadvantages such as time-consuming, high cost, and complicated operations, and inspectors generally require professional training ;The above detection methods are difficult to achieve rapid and large-scale detection, and only a small number of samples can be extracted for detection. The limitation of the number of samples tested causes the accuracy and representativeness of detection to decline; [0003] Figure 4 A plot of the results of the analysis of various milk sample...
