What is it about?
Starch granules have a conspicuous Maltese Cross when viewed using a polarizing microscope (there are many pictures in food science journals). But with a fully equipped polarizing microscope many other interesting features can be observed - like interference colors determined by the molecular structure of starch granules. Measuring things is a good way to understand them - hence colorimetry of the interference colors.

Why is it important?
Although photomicrographs of the Maltese Crosses on starch granules appear in many food science journals, I doubt whether many researchers really understand what they are looking at.
