Effect of fractional crystallization on composition and thermal behavior of coconut oil

This study was aimed to fractionate coconut oil into its high-and low-melting fractions and determine the composition and thermal property changes. A sample of coconut oil was cooled down in a state of a solution in acetone, and allowed to crystallize isothermally at 10oC for 6 h. When the crystalli...
