Starch¯alcohol complexes

Properties of starch complexes prepared from potato starch with methanol, 1-propanol and 1-pentanol are presented. These complexes were prepared from air-and oven-dried starch. It is demonstrated that alcohols penetrated the interiors of starch granules and expelled the amorphous content of the granules through the hilum. In this manner, original structure of granules is irreversibly changed.
