Abstract

A new process for enriching triterpene esters comprising: providing a mixture comprising a non-distilled vegetable oil and/or a non-distilled vegetable fat, further comprising triterpene esters, performing a mild transesterification with a lower alcohol, removing lower alcohol esters by deodorization, 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 triterpene esters. There is both the chance to fully keep the natural distribution of triterpene esters but in the other end also to replace the natural level of cinnamic and acetic acids-triterpene esters with a high level of long fatty acid triterpene-esters.
