Kpangnan butter solvent fractionation
Acetone fractionation was used to remove high melting and low melting
TAGs from the Kpangnan oil to obtain a higher proportion of SOS in the
final fractions. The ratio of Kpangnan oil: acetone was 1:4 w/w to
fractionate at three different temperatures of 16, 22, and 25 °C. In the
first acetone crystallization step, most of the SOS was fractionated,
while the second and the third fractionations were used to remove low
melting TAGs (SOO and OOO) and increasing SOS concentration.
