✦ Synopsis
Two standard titrimetric procedures for determination of free fatty acids in vegetable oils and in oils extracted from oilseeds were examined using rapeseed oil, illipe nuts and fat, and groundnuts and groundnut oil as test materials. Both procedures involve dissolution of the fat in an organic solvent and titration with standard alkali solution using phenolphthalein as indicator. Results obtained using each of the two methods agree closely in most cases and certainly for commercial contractual purposes the two methods are interchangeable. Suggestions are made for modification of these methods particularly in regard to solvents and allowed variation in analysis results.
