Extraction of Phytosterols from Jatropha seed oil by the Saponification and Acid hydrolysis method in chemical engineering

摘要

In this paper by means of orthogonal array design, the effect of sulphuric acid, time, temperature on the extraction rate of phytosterols was discussed with chemical technology. The optimal parameters for extracting phytosterols of Jatropha oil were as follows: 25g Jatropha oil with 0.25mL sulphuric acid by the 3.5h extraction at 55°C. Under the optimal conditions, the yield of phytosterols was up to 199mg/10g.
