The purpose of this investigation was to study the feasibility of using a polarized light detector (PLD) for measuring starch … WebbStarch phase transitions, birefringence, and swelling were measured in those containing highly unsaturated oils. Samples dispersed in added oil mixtures of oil, starch, and water containing oils of differing saturation, were examined microscopically. Some birefringence was present at the end fatty-acid chain length, and conformation.

WebbIf the starch granules, in a water suspension, are observed microscopically under polarized light, the highly oriented structure causes the light to be rotated so that a Maltese cross pattern on each granule is observed. This phenomenon is called birefringence. The pattern disappears when the starch mixture is heated and the structure disrupted.
