[Kinetic regularities of the interdiffusion process in a water-biopolymer system].

Kinetics of the process of interdiffusion in the system water-biopolymer has been investigated. Optical interference micromethod have been used to determine the interdiffusion coefficients in water-gelatin system. The average meanings of Dv for the water-gelatin system with gelatin concentration of 0-25% and temperature range of 293-328 K are 0.
