CHEMICAL CHARACTERISTICS AND FATTY-ACID COMPOSITION ON OILS AND FATS STORED IN DIFFERENT PACKAGING MATERIALS

Bleached cottonseed oil, partially hydrogenated palm oil and margarine were stored in metal (tin) cans and white plastic (polyethylene) bodi es with air in head space and served at room temperature during the wh ole period of investigation. The analytical techniques used to analyse these materials has been done at zero time storing (control), after l our and seven months oi storage. This study showed that storing oils i n metal cans have better results than plastic packages specially for b leached cottonseed and hydrogenated oils.
