Characterization of some seed oils of fruits for utilization of industrial residues

Cíntia Nanci Kobori Neuza Jorge About the authors

The purpose of this study was to characterize the extracted oils of the seeds of tomato, orange, passion fruit and guava with the objective of using industrial residues. The oils were extracted from the seeds with a Soxhlet extractor, using petroleum ether as solvent, and were characterized by standard methods for oil and fat analysis (free fatty acids, peroxide value, refractive index, iodine value, saponification value, unsaponifiable matter and oxidative stability). The analyses accomplished indicate that these oils possess similar physicochemical characteristics as some edible oils, them they can be a new source of oils for human consumption.
