In a previous report, we presumed that the amount of "fat-by-hydrolysis" may affect the viscosity of starch pasts. To confirm this presumption, we experimented with the effects of "fat-by-hydrolysis" on physical properties of starch paste using a Bravender Amylograph.It was shown that the gelatinization temperature and viscosity curve of starch paste rises slightly in proportion to the increase of the quantity of "fat-by-hydrolysis".Investigation of the introduction of fatty acid into the starch by surface active agents has shown that physical properties of starch treated by surface active agents are considerably different from original starch depending upon the kinds of surface active agents used. It has been shown that there is a formation of the amylose complex with surface active agents, when the starch is treated with thosh agents.When sodium salt of fatty acid is introduced into starch, it forms a complex with amylose, and the treated starch shows a distinctive corve on the Amylograph.
