As palmitic acid is the major fatty acid present in palm oil, it was
decided to investigate the effect of monopalmitin (MP) on the palm
oil crystallization behavior, because of its high degree of similarity
with the crystallizing palm TAGs. In their review, Smith et al.
criticize the fact that studied additives are mostly referred to by
their trade name and are not adequately analyzed while the precise
composition might vary, even from batch to batch. In this study, it
was decided to work with pureMP (>99%). In this way, the composition
was well known and observed effects could be completely attributed to
the MP. The influence of pure MP on palm oil crystallization has been
studied before, as well as the influence of monoglycerides of fully hydrogenated
PO, which contain a substantial
amount of MP. Miura, Yamamoto, and Konishi and Miura,
Yamamoto, and Sato only concluded that pureMP in a concentration
of 1% did not affect the solid fat content when crystallization
occurred at 5 °C. Moreover, all studied blends never had an emulsifier
concentration higher than 2%.
