In this work, the influence of the variables which can affect oil extraction from soybean enzymatically pretreated grit using hexane, were studied. From the experimental results, a mathematical model for calculating the extraction yield was proposed. The statistical tests used to obtain this model showed that the yield does not depend on the enzymatic incubation pH but on the temperature and time of enzymatic treatment and on the interaction between time and temperature. The proposed model fit the experimental data well.
