Abstract
The invention concerns a method of reducing the organoleptic effect of undesirable aldehydic components in a triglyceride or derivative thereof by addition of a reaction product of an amine and an organoleptically acceptable aldehyde. The triglyceride may be a food or food component such as an edible fat or a surface active agent such as a detergent. The reaction product may be incorporated in the perfume or flavor to be added to the triglyceride or derivative thereof without distorting their organoleptic effect.
