Title: ENRICHMENT OF TRITERPENE ESTERS
Abstract:
A new process for enrichment of triterpene esters, said process comprises the steps of: a) providing a mixture comprising a non-distilled vegetable oil and/or a non-distilled vegetable fat, further comprising triterpene esters, b) performing a mild transesterification with a lower alcohol, c) removing lower alcohol esters by deodorisation, physical refining, evaporation or distillation, and recovering the remaining fraction rich in triterpene esters. Triterpene esters enriched with the method as well as uses of the same are also provided. One advantage is that it is a more economically viable way of achieving higher concentration of TTP esters. There is both the chance to fully keep the natural distribution of TTP esters but in the other end also to replace the natural level of cinnamic and acetic acids-TTP esters with a high level of long fatty acid TTP-esters.
