AI Technical Summary
The lack of efficient methods for purifying and separating lutein monoesters in existing technologies results in low bioavailability and poor stability in the human body, failing to meet the needs of those with rapid absorption or weak digestive and absorptive functions.
By employing a specific solvent for the first cooling crystallization, combined with a lipase hydrolysis reaction and a second cooling crystallization, and by controlling the reaction conditions and washing steps, the purity and yield of lutein fatty acid monoesters can be improved.
High-purity extraction of lutein fatty acid monoesters was achieved, with a purity of over 70%, making it suitable as a nutritional supplement or food additive, and exhibiting good stability and bioavailability.
