Background. The effects of boiling and frying on the bioaccessibility of all-trans-?-carotene in biofortified BRS Jari cassava roots have not been investigated, although these are conventional methods of cassava preparation. Objective. The aims of the present study were to investigate B-carotene micellarization efficiency of yellowfleshed BRS Jari cassava roots after boiling and frying, as an indicator of the bioaccessibility of this carotenoid, and to apply fluorescence microscopy to investigate B-carotene in the emulsified fraction. Methods. Uncooked, boiled, and fried cassava roots were digested in vitro for the evaluation, by reversedphase high-performance liquid chromatography (HPLC), of the efficiency of micellarization of all-trans-B-carotene in BRS Jari cassava roots. Fluorescence microscopy of the micellar fraction was used to confirm the presence of B-carotene in the emulsified fraction and to observe the structure of the microemulsion from the boiled and fried cassava samples. Results. Fried cassava roots showed the highest (p < .05) micellarization efficiency for total carotenoids and alltrans-B-carotene (14.1 ± 2.25% and 14.37 ± 2.44%, respectively), compared with boiled and raw samples. Fluorescence microscopy showed that after in vitro digestion there were no carotenoid crystals in the micellar fraction, but rather that this fraction presented a biphasic system compatible with emulsified carotenoids, which was consistent with the expected high bioavailability of B-carotene in this fraction.
