Abstract
A method of processing agricultural oil in which non-toxic reagents are used, so that a waste stream is evolved suitable for use as a nutrient source and wherein the non-toxic reagents include nutrient source and wherein the non-toxic reagents include nutrient components whereby the nutrient value of the waste stream is enhanced. A variation of convention refining is detailed in which potassium hydroxide is used as refining caustic instead of conventional sodium hydroxide. The resulting process exhibits improvements in waste wash characteristics, more complete oil recovery, less oil in the soapstock, reduced interlayer formation, more soap removed from the refined oil into the soapstock stream, and a less viscous soapstock.
