Peels of tucumã (Astrocaryum vulgare) and peach palm (Bactris gasipaes) are by-products classified as very high carotenoid sources

In this study, for the first time, both the extraction of carotenoids from the peel of tucumã and peach palm fruits and their carotenoid profile were investigated. The carotenoid contents of the peel of both fruits were higher than those found in the pulp. The highest yield of carotenoids from both fruit peels were obtained at the solid-liquid ratio of 1:7 (w/v), 80 min of shaking and by adding 30% of ethyl acetate in acetone, being β-carotene the major carotenoid (7.8 and 7.3 mg/100g for tucumã and peach palm, respectively), followed by γ-carotene and δ-carotene. Thus, peels of tucumã and peach palm fruits were classified as very high carotenoid sources to be used by any potential interested industry.
