| Popis: | In this study the native carotenoids composition in kumquat (Fortunella margarita) (peel + pulp) from Brazil was determined for the first time by a HPLC-DAD-APCI/MS (high performance liquid chromatography-diode array detector-atmospheric pressure chemical ionization/mass spectrometry), methodology. Eleven carotenoids were successfully identified and quantified in kumquat: four carotenoids in the free form and seven carotenoids in the esterified form. &beta citraurin-laurate was the carotenoid found in the highest content (607.33 µ g/100 g fresh matter), followed by &beta cryptoxanthin-laurate (552.59 µ g/100 g). The different esterified forms of &beta citraurin and &beta cryptoxanthin represented 84.34% of the carotenoids found, which demonstrates the importance of esterification in natural fruits. &beta carotene and free xanthophylls (&beta cryptoxanthin, lutein and zeaxanthin) represented 5.50% and 14.96%, respectively, of total carotenoids in kumquat. The total carotenoid content of kumquat from Brazil was very high (2185.16 µ g/100 g), suggesting that this fruit could contribute significantly to the intake of important bioactive compounds by the population. |
