An enzymatic route to synthesize lutein esters was investigated using a lipase-Pluronic conjugate as the catalyst. For the synthesis of lutein palmitate, the enzymatic process gave a conversion of 85 % for lutein and a product purity of 96 % at 50 °C within 12 h, whereas the free lipase catalyzed process achieved a conversion below 10 %. To demonstrate the generality of this enzymatic process, lutein...
We report the first example of enzymatic synthesis of lutein dipalmitate in organic solvents by using a commercial immobilized Candida antarctica lipase B (Novozyme 435) as the catalyst. At the optimized condition, by using 20 mg/mL of lutein, 100 mg/mL of vinyl palmitate as the substrates, and 20 mg/mL of Novozyme 435 as the catalyst, the enzymatic synthesis in toluene achieved...
