Moisture sorption isotherms of whey powder spray in the temperature range of 10oC -- 40oC

Original language description

The paper presents results of water sorption tests of whey powder spray carried out under laboratory conditions and mathematical analyses of sorption isotherms. Moisture equilibrium data were investigated at air temperatures in the range of 10 - 40oC andwater activity ranging from 0.3 to 0.99. The experimental procedure used was a gravimetric dynamic method with the continuous registration of sample weight changes. A special laboratory drying device has been developed for the purpose. Sorption capacitydecreases as temperature increases. Rehydration of the dried material results in hysteresis but this phenomena was small. Four models of equilibrium moisture content/water activity (Chung-Pfost, Halsey, Henderson, and Oswin) were evaluated for their ability to fit data for the samples tested. The Henderon´s equation was a good model for moisture adsorption and desorption of whey powder spray.
