It is considered that, in the amylose-iodine complex, the helical amylose moiety polarizes the trapped iodine molecules, generating blue color in the product'. The stability of the complex depends2 on such factors as the temperature, the pH, and the additives. The standard free-energy, enthalpy, and

In aqueous solutions of the amylose-iodine complex the concentration of free iodine [Illv after reaching equilibrium (or closely approximating it) is determined by the following factors: temperature, pH, concentration of iodide ions and amylose, and f% of amylose. In the present paper the role of te
## Abstract Using a potato amylose fraction of 8 × 10^5^, molecular‐weight viscosity studies were carried out at 25°C on solutions containing 0.176–0.042% polymer, 8.67 m__M__ KI, 1% ethanol, and different concentrations of iodine. By a novel extrapolation method, the intrinsic viscosities of the a
