1. A jojoba wax ester product prepared by the process comprising:
continuously contacting a feedstock with an immobilized lipase enzyme catalyst, wherein the feedstock comprises feedstock wax esters and a feedstock tocopherol, wherein the feedstock wax esters comprise jojoba wax esters and hydrogenated jojoba wax esters; and
continuously reacting the jojoba wax esters and the hydrogenated jojoba wax esters in the feedstock using the immobilized lipase enzyme catalyst to yield a product comprising transesterified product wax esters and the feedstock tocopherol.
