1. A process for enriching triterpene esters comprising:
providing a mixture comprising at least one non-distilled vegetable oil or non-distilled vegetable fat, wherein the mixture further comprises at least one triterpene ester,
performing a mild transesterification with at least one lower alcohol at a temperature equal to or lower than the boiling point of the mixture, to obtain lower alcohol esters,
removing the lower alcohol esters by at least one procedure chosen from deodorization, physical refining, evaporation and distillation, and
recovering the remaining fraction rich in triterpene esters.
