The overall reaction occurs in sequence of three continuous stages as shown in Figure
3.3. (a) conversion of TGs to DGs, (b) conversion of DGs to MGs and (c) conversion of MGs
to glycerin. R represents FA; R1, R2 and R3 represent the hydrocarbon chains of the fatty
acid alkyl groups of the triglyceride (Ghaly et al., 2010; Marchetti et al., 2008). For each
molecule of triglyceride, three molecules of alcohol are needed to produce three molecules of
fatty esters. The transesterification reaction of acyl-acceptors can involve carboxylic acids, in
which case the reaction would be known as acidolysis, or alcohol, with alcoholysis, or
another ester with interestification. These reactions, alcoholysis and interesterifi
