Ultrasound-assisted oil extraction from Ricinus communis L. seed
Abstract The aimed of this work was to determine the optimal conditions for oil extraction of Ricinus communis L. seed by means of ultrasound. The effect of 3 factors over oil yield extraction were evaluated: 1) seed pretreatment 2) ultrasound time and 3) solvent mixture ratio compared to conventional Soxhlet extraction. The optimal conditions for oil extraction were obtained with a pretreatment that consisted in washing and drying of the seed, with a 2.5 h exposure to ultrasound in a mixture of hexane/isopropanol solvents (1:1 v/v). The extraction yield was 73.5% with an extraction rate of 1.8 g.h-1.
