VISCOSITY OF GLUCOSE SOLUTIONS PREPARED IN WATER SUBJECTED TO AN ELECTROMAGNETIC FIELD

Abstract

The paper presents the results of a study of the rheological properties of glucose solutions prepared using water exposed to an electromagnetic field with a frequency of 30 to 200 MHz. The studies were carried out with solutions with a concentration of 20%, the shear rate varied in the range of 100–1000 s-1. As a result of the study, a distinct influence of the influence of the electromagnetic field was found, while the quantitative response depends on the shear rate, frequency of the electromagnetic field and the time of exposure of water from the moment of field exposure to preparation of the solution. In the overwhelming majority of cases, there is a decrease in the viscosity of solutions at a shear rate of 1000 s-1 as a result of exposure to an electromagnetic field. A quantitative correlation between the change in viscosity and the frequency and time of post-field exposure was not found. In some cases (shear rate 200 and 500 s-1), there is a multidirectional change in viscosity versus exposure time. The results are compared with those previously obtained for agar solutions. A unidirectional change in the viscosity of glucose and agar solutions was found as a result of the action of an electromagnetic field on the solvent, which can serve as evidence of its structural reorganization. An explanation for the observed dependences is proposed, which is based on a change in the hydration interactions of glucose molecules in solution and, as a consequence, a change in the force and energy characteristics under shear stresses.
