Some Observations on the Stability of Amylose and Amylopectin in Aqueous Solution

Results are presented for a series of light-scattering experiments on the stability of the starch components, amylose and amylopectin, in 0.33 M KCl. Potato, regular maize amylose, and the amylose from two amylomaize starches have been studied. The findings are generally in agreement with previous studies in this area, but in the case of amylopectin, contrary to the findings of Čeh and Vene, no retrogradation has been observed.
