Abstract

AbstractThe effect of a number of physical methods for the removal of sulfur compounds from canola oil was investigated. The methods tested included laboratory deodorization and use of catalyst and of bleaching earth. Nine temperature‐time combinations were used for the deodorization. Bleaching earth had little effect on the removal of sulfur compounds from the oil. Other methods removed part of the sulfur. High temperature, longer time and high vacuum for deodorization facilitated the complete removal of volatile sulfur compounds. Treatment of oil with catalyst removed most of the volatile sulfur and part of the Raney nickel sulfur.
