Citric Acid under Polarizing Microscope

The image below of Citric Acid was captured by Jan l'Amie in the Netherlands. Jan used the BYO-500T microscope, which is a University level trinocular Siedentopf microscope. He captured the image using a PL 10x objective lens with a polarizing filter. The Canon EOS 50D DSLR camera was connected to the microscope with a photo tube fitted with a 2.5x photo eyepiece.

Citric acid is a natural preservative that is present in citrus fruits. Citric acid is also used to add an acidic or sour taste to food or drink. Citric acid is known as a commodity chemical, as more than a million tons are produced every year by fermentation.
