Objetivou-se avaliar as alterações de b-caroteno, ácido ascórbico e antocianinas totais na polpa de frutos de clones de aceroleira conservada por congelamento. Os frutos dos clones BRS 152 (Sertaneja) BRS 235 (Apodi), BRS 236 (Cereja), BRS 237 (Roxinha), BRS 238 (Frutacor) e II 47/1 foram colhidos no estádio de maturação comercial (vermelho maduro) em Limoeiro do Norte, Ceará, Brasil, transportados para a Planta Piloto de Processamento de Frutos da Embrapa Agroindústria Tropical, despolpados, acondicionada a polpa em sacos de polietileno (100 g), congelada, mantida em freezer a -20 °C, e avaliada a cada 30 dias durante 12 meses. O experimento foi realizado em delineamento experimental inteiramente casualizado em esquema fatorial 6 x 13 (clones x tempo), com 3 repetições. A concentração de beta-caroteno foi estável no clone Cereja, enquanto, nos demais, houve decréscimo durante todo o período do experimento. Houve pequeno decréscimo no teor de ácido ascórbico em todos os clones estudados durante o armazenamento, provavelmente devido à alta acidez da polpa, que auxilia na manutenção deste nutriente. O teor de antocianinas totais foi estável nos clones Frutacor e Sertaneja, enquanto nos demais houve diminuição. O clone II 47/1 foi dentre os estudados o que apresentou maiores teores de ácido ascórbico e antocianinas totais, mantendo estas características durante todo o armazenamento. De um modo geral, os clones em que se determinou menor teor de beta-caroteno foram observadas as mais elevadas concentrações de antocianinas totais. The objective of the work was to evaluate b-carotene, ascorbic acid and total anthocyanins alterations in fruit pulp of acerola tree clones conserved by the cold. The fruit clones BRS 152 (Sertaneja), BRS 235 (Apodi), BRS 236 (Cereja), BRS 237 (Roxinha), BRS 238 (Frutacor) and II 47/1 were harvested in a commercial maturation stage (ripe red) in Limoeiro do Norte, Ceará, Brasil, carried to Planta Piloto de Processamento de Frutos da Embrapa Agroindústria Tropical, unpulped, the pulp was storaged in polietilin bags (100 g), frozen, kept in a freezer at -20 °C, and evaluated every 30 days for 12 months. The experiment was carried out with experimental delineament totally casualized in a factorial scheme 6 x 13 (clones x time), with 3 repetitions. The concentration of beta-carotene in the Cereja clone was stable, while the other ones were decreased during the whole time of the experiment. There was a small decrease in the ascorbic acid level in all the clones in the study during the storage, probably due to the high acidity of the pulp, which helps maintain its nutrient. The total anthocyanins level were stable in the Frutacor and Sertaneja clones, however, it decreased in the other ones. The II 47/1 clone was, among all the studied clones, the one that presented the highest levels of ascorbic acid C and total anthocyanins, keeping these characteristics during the whole storage. In conclusion, the clones that presented the lowest level of beta-carotene, showed the highest concentrations of total anthocyanins
