OLIVEIRA, R. G. A.; CARVALHO, M. J. L. de; NUTTI, R. M.; CARVALHO, L. V. J. de; FUKUDA, W. G..
The assessment of the variability of total carotenoid, ß-carotene, all-E, and 13 and 9-Z-ß-carotene isomers in twelve bitter yellow cassava was carried out, as well its degradation in five varieties after flour processing and during storage. HPLC and UV/ visible spectrophotometry were used in sample analyses. Varieties of bitter yellow cassava presented variation in the total carotenoid contents from 1.97 - 16.33 ?g/ bg and the ß-carotene contents varied from 1.37 - 7.66?g/ g. The 13, 9-Z and all-E-ß-carotene isomers were found in all varieties, being all-E-ß-carotene the predominant one. The mean degradation among the roots after processing was of 50%. Total carotenoid complete degradation was observed with less than 30 storage days. It was also observed...
