Abstract
Processes for transesterifying wax esters. Implementations may include: providing a feedstock including wax esters, contacting the feedstock with a lipase, and catalytically transesterifying the wax esters in the feedstock with the lipase to form a transesterified product. An oxidative stability index (OSI) of the transesterified product may be greater than an OSI of the feedstock.
Claims20
A process for enzymatically transesterifying wax esters with one another, the process comprising the steps of:
- contacting a feedstock with a transesterification enzyme catalyst, wherein the feedstock comprises a) feedstock wax esters that comprise jojoba wax esters and hydrogenated jojoba wax esters, and b) an original amount of a feedstock tocopherol, and wherein the transesterification enzyme catalyst comprises a lipase enzyme catalyst;
- and
- enzymatically transesterifying the feedstock wax esters using the transesterification enzyme catalyst to cause transesterification of the feedstock wax esters with one another to form a reaction product mixture comprising enzymatically transesterified wax esters and the original amount of the feedstock tocopherol, and wherein the reaction product includes 5 weight percent or less fatty methyl esters and free fatty alcohols.
A process for preparing a randomized wax ester composition comprising enzymatically randomized wax esters and an antioxidant, comprising the steps of:
- contacting a feedstock with a transesterification enzyme catalyst, wherein the feedstock comprises a) feedstock wax esters that comprise jojoba wax esters and hydrogenated jojoba wax esters, and b) the antioxidant, and wherein the transesterification enzyme catalyst comprises a lipase enzyme catalyst;
- and
- enzymatically randomizing the jojoba wax esters and the hydrogenated jojoba wax esters in the feedstock with one another using the lipase enzyme catalyst to provide the randomized wax ester composition comprising the antioxidant and the enzymatically randomized wax esters, and wherein the reaction product includes 5 weight percent or less fatty methyl esters and free fatty alcohols.
