1. A process for the maintaining of a ratio of stereoisomers of carotenoid compounds of formula (I) wherein R1 and R2 are independently of each other wherein the compounds of formula (I) are mixed with less that 1 wt-%, based on the total weight of the compound(s) of formula (I), of at least one alkali and/or earth alkali metal salt of an organic acid. |
