Refined, Bleached and Deodorized Palm Stearin (RBDPS) is a solid fraction obtained from Refined, Bleached and Deodorized Palm Oil after fractionation by crystallization at controlled temperature. Fractionated RBDPS was found to be enriched with C16 fatty acids, lacking in trans fat and has a high melting point. The fractionated RBDPS produced had an iodine value of 13.1 gI2/100g, C16 content of 79.7% and melting point 60?C. These characteristics indicate fractionated RBDPS has potential as a rumen bypass fat as well as providing desirable carbon chain composition for good milk characteristics.
