Fig.1 Principal component analysis of milk mixed with different volumes of water

The 14-sensor iNose electronic nose is used to distinguish between different brands of milk powder: the experimental results show that whether using PCA or LDA analysis, in the iNose electronic nose model of 14 sensors built, different brands of milk powder samples The analytical data points are distributed in their respective regions. Except for the partial overlap of Beinmei and Youcon, the distance between the other samples is larger. The 14 sensors' iNose electronic nose can accurately identify and distinguish different brands of milk powder.

Figure 2 Bright milk powder adulteration test

14 sensors of iNose electronic nose for the detection of adulterated milk powder: experimentally available, 14 sensors of iNose electronic nose test data showed by PCA and LDA analysis, blended with 20% soy flour, urea and vegetable fat At the end of the day, the electronic nose map of Bright Milk Powder also changed significantly. The use of 14 sensors of iNose electronic nose for the detection of adulterated milk powder is based on the influence of the odor of the admixture, and the second is the decrease in the content of the milk powder due to the incorporation of other substances.

Figure 3: Odor distribution of yogurt in different storage periods

The application of 14 sensors of iNose electronic nose in the differentiation of yogurt in different shelf life: as the storage time increases, the odor of the sample will change, and the 14 sensors iNose electronic nose can accurately identify the 6 samples. The characteristic smell and can distinguish it.

Figure 4 Distribution of high quality raw milk and odor raw milk

The application of 14 sensors of iNose electronic nose in distinguishing different odor raw milk: the odor of high quality raw milk and odor raw milk samples is quite different, 14 sensors of iNose electronic nose can accurately identify the two samples Characteristic odors and can distinguish them.

Figure 5 Analysis of the main components of the three original cheeses

Application of 14 sensors for iNose electronic nose technology in cheese identification: The 14-sensor iNose electronic nose reflects the overall information of the sample odor. The experimental results show that the three cheeses belong to different regions, and the 14 sensors of the iNose electronic nose can be easily distinguished.
