Title: Variation in the carotenoid composition of acerola and its processed products
Author: Porcu, OM

Abstract: Acerola is now commercially produced and processed in Brazil. Known for its very high vitamin C content, this fruit is also a good source of beta-carotene. The present study was carried out to verify variation in the carotenoid composition along the food chain. Neoxanthin, violaxanthin, lutein, P-cryptoxanthin, a-carotene and beta-carotene were found in the acerola fruit. beta-Carotene predominated with mean concentrations of 12.4 and 38.1 mu g g(-1) in the ripe fruit, 8.8 and 30.1 mu g g(-1) in the peeled ripe fruit and 5.4 and 12.0 mu g g(-1) in the partially ripe fruit of an undefined variety taken from home gardens and the commercial cultivar Olivier, respectively. Aside from beta-carotene, beta-cryptoxanthin increased significantly in both garden and commercial fruits and violaxanthin in the latter fruits during ripening. Peeling reduced beta-carotene in both garden and commercial lots, violaxanthin decreased in the commercial fruits, and the other carotenoids remained virtually unchanged. Four brands of frozen pulp and three brands of processed juice had variable and markedly lower carotenoid levels than those of the fresh fruit, indicating that the processing should be improved.
