Interaction of Surface Active Agent with Amylose

Abstract It was found that a specific precipitate is formed when some ionic surface active agents are added to amylose solution and it was confirmed by X-ray diffraction study that this phenomenon is due to the formation of the helical complex between amylose and a surface active agent. It is also inferred that the same complex is formed even in the dissolved state from the study on the effect of the surface active agent on the viscosity of amylose solution and on the absorption spectrum of amylose-iodine complex.
