Abstract

The method consists in dissolving in a mixture of diethyl ether and ethanol of the oil extracted for the determination of the "oil contend" of the seeds (see ISO 659), and then titrating of the free fatty acids present using an ethanolic potassium hydroxide solution. It is not applicable to cotton seeds with adherent cotton linters, or to palm or olive fruits.
