Resumen
The effects of process variables on the oil extraction from passion fruit seeds by three techniques, ultrasound shaker, and soxhlet, and of environment-friendly solvents are evaluated. Ratio variables of seed weight, solvent volume (R), time of extraction (T), and type of solvent (S) were evaluated. The significant variables for oil extraction from passion fruit seeds were R and S by ultrasound and shaker techniques and T for soxhlet extraction. Comparison of the three techniques showed that the soxhlet technique had the highest yield with 65% of total oil in the initial matrix.
