Abstract
This study explored the solid fat index (SFI) of structured lipids (SLs) synthesized by lipase-catalyzed (Lipozyme TLIM) interesterification using hydrogenated coconut oil (HCO), palm oil (PO) and palm stearin solid (PSS). SLs were produced using three blends of HCO/PO (60:40, w/w), HCO/PSS (40:60 and 60:40, w/w), and HCO/PO/PSS (32:48:18, w/w/w) to find a desirable confectionary fat by monitoring melting and crystallization behaviors of SFI of SLs using differential scanning calorimetry (DSC). SFI of HCO/PSS (60:40) and HCO/PO/PSS (32:48:18) at $25^{\circ}C$ were 70% and 68%, respectively. These results suggest that HCO/PSS (60:40) and HCO/PO/PSS (32:48:18) may be useful as potential SLs of a confectionary fat.
