Fat Acidity -- Rapid Method, for Small Grains

VIEW METHOD

Objective
Natural fats are mixtures of esters of fatty acids with glycerol. They are essentially neutral. Unfavorable storage conditions may cause partial hydrolysis of the glycerides. The resultant free fatty acids increase the acidity, which is an indication of deterioration in quality. This method determines total fatty acids in small grains by a rapid titrimetric procedure.
