Abstract

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 0.3 x 10(-10) m2/s to 1.57 x 10(-10) m2/s depending on the temperature and kind of gelatin.
