- •
A cleanup method for the identification of carotenoid esters by LC–MS is proposed.
- •
Carotenoid ester profile of murici is reported for the first time.
- •
Only after cleanup, 29 out of 35 carotenoids from murici were identified.
- •
83% of the carotenoids present in murici fruits are found in the esterified form.
