Among the fruit species that can be used to develop new products is the umbu-caja tree (Spondias spp.) due to the economic potential of its fruits, good processing characteristics, pulp yield of more than 50% as well as pleasant sensory properties of smell and taste. Belonging to the family Anacardiaceae, the umbu-caja fruit tree is native to northeastern Brazil and still in the domestication phase. It originated from possible natural cross-breeding between the umbu (S. tuberosa Arr. Cam.) and the caja (S. mombim L.), which exhibits marked variability as a function of morphological variations between leaves and fruits (Lira Júnior et al. 2005). Its fruit, the umbu-caja, is a drupe with smooth epicarp, thin-skinned and color ranging from yellow to yellowish-green when ripe. The juicy mesocarp varies from highly acidic to sweetened in some genotypes, whereas the endocarp, the innermost layer, is fibrous (Carvalho et al. 2008).
