Abstract

The invention discloses milk quality detection equipment and a milk quality detection method. The milk quality detection method comprises the following steps: firstly, selecting three types of carrier gases for detecting volatile gases produced by n types of milk samples so as to obtain n w1s related to the milk content of milk powder; secondly, constituting points (w1, E) from the w1s and the milk content E of the milk powder related to the w1s; thirdly, according to the n points (w1, E), fitting a detection model, and computing the fitting precision R; fourthly, selecting a milk quality predetection model; and finally, computing the milk powder content E of the milk K by a computer according to the milk quality predetection model, and computing the milk powder content. The milk quality detection equipment and the milk quality detection method have the characteristics of capability of quickly detecting the milk powder contents in the milk samples, and relatively high detection accuracy and higher reliability.

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, instrumental analysis and principal component analysis are used to detect milk quality; however, physical and chemical testing and instrumental analysis have the disadvantages of time-consuming, high cost, and complicated operations, and inspectors generally require professional training The above-mentioned detection method is difficult to realize rapid and large-scale detection, and only a small number of samples can be extracted for detection. The limitation of the number of samples detected causes the accuracy and representativeness of detection to decline; [0003] Figure 4 A plot of the results of the analysis of various milk samples using principal component anal...
