Food Analysis with hyperspectral cameras for quality control and automated sorting

In food analysis, NIR spectroscopy for determining chemical constituents has gained importance in recent years. However, commonly fiber-coupled line spectrometer are in use, since they have been the state-of-the-art so far.

Our innovative HSI camera technology will change that fundamentally and open up new ways of analyses. As industrialized HSI systems, they can be integrated into production processes for quality assurance.

The image above shows a hyperspectral image of the porcine meat sample with typical spectral ranges and a principle components analysis (PCA). Clearly visible is the distinction of fat, muscle, cartilage and bone tissue in the spectral range between 500 nm and 1000 nm.

As a further example, the image below shows different potato products.
