The hygroscopic capacity of most of seeds and agricultural grains have already been studied, however, it can be observed in the specialized literature a lack of reports on equilibrium moisture content of seeds of jacaranda-da-bahia (Dalbergia nigra Fr. All.), angico-vermelho (Anadenanthera macrocarpa Benth.) and óleo-copaiba (Copaifera langsdorffii Benth.). This research objectived to determine the desorption curves for these seeds, and to adjust different mathematical models already traditionally used for another seeds, to the experimental data. The equation of Sigma- Copace, with the constants determined for the species of jacaranda-da-bahia and angico-vermelho, was the model that better adjusted to the experimental data, while for óleo-copaiba the of Henderson- Modified equation represented better the experimental data.
