Microemulsion-based peanut oil extraction using surfactant solution

Nowadays, vegetable oil is an alternative for the substitution of biodiesel. Vegetable oil extraction is more favourable by using surfactant compared to hexane which is hazardous to human. In this study, extraction efficiency and physical appearance of oil extracted by Brij-30, GE-460 and their mixt...
