Q. Development of off-flavours and objectionable taste in fats?
Autoxidation leads to the development of off-flavours and objectionable taste in fats. The initial oxidation products that are formed are hydroperoxides and are measured by iodimetric methods. The peroxide value of the freshly deodorized fat should be nil and a fat received directly from a processor should seldom exceed a peroxide value of 1.0. Most fats are deemed rancid when their peroxide values are between 10 and 20.
