What is the fatty acid composition of palm olein versus palm stearin post fractionation?
The resulting two components of the palm oil fractionation (see ‘What is fractionation’) is palm olein (liquid) and palm stearin (solid). The fatty acid composition of palm olein is approximately 45% saturated fat and 55% unsaturated fat. The main saturated fatty acids are 40% palmitic acid and 5% stearic acid. The unsaturated fatty acids are 43% oleic acid (monunsaturates) and 12% linoleic acid (polyunsaturates). The fatty acid composition of palm stearin is approximately 60% saturated fat and 40% unsaturated fat. The main saturated fatty acids are 54% palmitic acid, 5% stearic acid, and 1% myristic acid. The main unsaturated fatty acids are 33% oleic acid (monounsaturates) and 7% linoleic acid (polyunsaturates). The main saturated fats in both palm olein and palm stearin are palmitic acid and stearic acid which may be neutral fats on cholesterol (see ‘Which is better trans fats or saturated fats?’).
