| Abstract: |
| Five transesterification products obtained at different flow rates (34,63,87,103,120 mL/min)were prepared by Lipozyme TL IM lipase transesterification of soybean oil with fully hydrogenated palm oil in packed bed reactor (PBR). The solid fat content (SFC), melting and crystallization properties of the raw material physical blend and products under different temperatures were characterized by differential scanning calorimetry (DSC) and pulse nuclear magnetic resonance (p-NMR). The results showed that the contents of UUU and SSS in transesterification products decreased, and the contents of SSU and UUS increased. The melting points and crystalline starting points of transesterification products were lower than those of raw material physical blend, which were 53.81?℃ and 3719?℃. The SFC of transesterification products were lower than that of raw material physical blend at temperature higher than 25?℃. The transesterification rate achieved 91.32% at flow rate of 103 mL/min (production yield 130 kg/d). The results were helpful for the high efficiency industrial production of margarine based oil. |
