MONTES, EVERALDO et al. MODELS OF DESORPTION ISOTHERMS OF YAM (Dioscorea rotundata). Dyna rev.fac.nac.minas [online]. 2009, vol.76, n.157, pp.145-152. ISSN 0012-7353.
It has been experimentally determined the equilibrium moisture content values for yam (Dioscorea rotundata 9811-089 and 9811-091) at 45, 55 and 70ºC temperatures and moistures between 10 and 67%. Samples were adapted to 6.38 cm diameter and 0.5 cm thickness slices.Employing the experimental technique of dynamic method to determine the desorption isotherm. Obtained data were analyzed for each temperature, being determined isotherms for the studied varieties, which were statistically equal to each other at the same temperature. Desorption isotherms were fixed to GAB, BET, Smith, Oswin, Henderson and Peleg mathematic models and was determined that the Peleg model is the most adequate for correlate the obtained data.
