Hypothesis
Can Lecitase® Ultra effectively catalyze the direct esterification of glycerol with oleic acid in a solvent-free system to produce 1,3-DAG?
Conclusion
Lecitase® Ultra can rapidly synthesize 1,3-DAG in a solvent-free system with high efficiency and yield.
Supporting Evidence
- The optimal conditions for producing 1,3-DAG were identified as a mole ratio of 1:5 for oleic acid to glycerol, a temperature of 40°C, and a reaction time of 1.5 hours.
- The esterification efficiency reached 80.3% and the 1,3-DAG content was 54.8% under optimal conditions.
- The study demonstrated that a solvent-free system significantly improved the esterification efficiency compared to traditional organic solvent methods.
- Recycling of the enzyme was shown to be effective, maintaining a high level of 1,3-DAG content over multiple runs.
Takeaway
This study shows that a special enzyme can help make a type of oil quickly and without using any harmful solvents.
Methodology
The study involved using Lecitase® Ultra to catalyze the esterification of glycerol and oleic acid under various conditions, including mole ratio, temperature, and enzyme load.
Limitations
The study did not explore the long-term stability of the enzyme or the economic feasibility of the process at a larger scale.
