The energy availability of palm oil, palm olein and palm stearin was determined by growth responses of young rats under conditions of energy restriction. The energy values are found to be 8.92 kilocalories per gram (kcal/g) for refined, bleached and deodorised (RBD) palm oil, 9,06kcal/gfor RBD palm olein and 8.55kcal/gfor RBD palm stearin, based on the energy availability of 8.93kcal/g established for cottonseed oil. These findings indicate that for practical purposes, the traditional use of 9.0kcal/g as the energy availability of edible fats is appropriate for RBD palm oil and RBD palm olein.
