The physicochemical patterns of interactions in the starch-glycerol-epoxidized soybean oil system were studied. On the basis of rheological curves, the effect of plasticizers on the viscosity of glycerin-starch systems was revealed, depending on the shear rate, time of exposure at temperature, and the nature of starch. The effect of epoxidized soybean oil on the viscosity of glycerin-moist starch systems was revealed. On the basis of IR spectroscopic studies and refractive index values, the existence of interactions between the system components was confirmed. The influence of the nature of the plasticizer on the ability to wet the surface of the plasticized starch was determined using the marginal wetting angle.
