PO blend with 50% of PB-DAG, not only, had the required
concentration of DAG (more than 40%) to exert beneficial effects
but also, had very close SFC profile with the commercial palm-based
shortening (unpublished data).
Slow crystallization of PO as well as formulation containing high
content of PO (Aini & Miskandar, 2007) may cause post-hardening in
palm-based margarines during storage which is clearly undesirable in
palm-based refrigerated margarines (Duns, 1985). Thus, from
the standpoint of potential application, using high concentrations of
PB-DAG (N40%) in palm-based refrigerated margarines not only is of
nutritional interest but also, might be of technical interest to inhibit
post-hardening in such products.
