Abstract

Different models of equilibrium moisture content of seeds: D’Arcy-Watt (DAW), Chung-Pfost (CHP) and Socorro (SOC) were compared in this paper. The cultivars used were beet (Beta vulgaris L. cv: PK-7); eggplant (Solanum melongena L. cv: FHB-1); cabbage (Brassica oleracea L. cv: Georgia L-9); lettuce (Lactuca sativa L. cv: GR-30); pepper (Capsicum annum L. cv: Chay L-3) y carrot (Daucus carota L. cv: P-29). Soybean seed moisture content values (Glycine Max L.) at 20 and 30 oC were used from references for fitting with Henderson-Thompson model. The equations of Oswin-Modified and Socorro were mathematically unified to obtain a new equation (OSW-SOC) with the temperature dependence directly. The OSW-SOC equation was compared with a regression comparative analysis, with respect to D’Arcy-Watt coefficients, using cotyledons of cowpea (Vigna sinensis Enal), faba bean (Vicia faba L.) and peanut (Arachis hypogaea L.). The fit by DAW, CHP and SOC model with high adjustment coefficients was obtained, as well as HTH model was appropriate for soybean grains. This allows us a model adequate selection for each species in the elaboration of informatic tools to manage these variables during the storage process. The new equation (OSW-SOC) obtained, was fitted regarding DAW with a high percentage on the respective cotyledons of the three species used.
