Is it easy to tell the difference between an immature and a ripe banana? Yes, but this can now be done electronically. IRIS is an imaging system that analyses both the colour composition of an object as well as other surface characteristics, such as size and circularity. The pixel-based part of the program can of course not only usable on bananas, but has the possibility to follow all colour changes in a product: bananas, meats, cheeses, cosmetics, tablets and many other materials.
Again, the strongest part of the system might well be the AlphaSoft software that enables a quantitative and statistical evaluation of the measurement results using the statistical data processing and chemometric analysis package, which over time will reduce or eliminate the necessity of a sensory panel.
