Physico-chemical properties of palm olein fractions as a function of diglyceride content in the starting material

Crude olein preparations with different amounts of diacylglycerols (DAG) were refined, bleached and deodorized (RBD) prior to the dry fractionation process. The RBD olein samples with different amounts of DAG were then individually fractionated into low-melting (super olein) and high-melting fractio...
