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 b-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 b-carotene, showed the highest concentrations of total anthocyanins.

This work aimed to increase, through the reduction storage temperature, the post-harvest conservation time of the early dwarf cashew tree peduncle of clones CCP 76 and END 183. It was carried out in the Postharvest Physiology and Technology Laboratory of the Embrapa Agroindústria Tropical in Fortaleza (State of Ceará, Brazil) using a factorial scheme in a randomized design with three replications of the factors (clones and storage duration: 0, 5, 10, 15, 20, 25 and 30 days). The fruits evaluated were manually harvested in a farm located in the Municipality of Beberibe, State of Ceará, transported in plastic containers to the Laboratory and stored in extruded polystyrene trays at the temperature of 3,4 ± 0,6ºC and relative humidity 85 ± 11% under modified atmosphere. The parameters evaluated were weight loss; appearance; peel color; pulp firmness; total soluble solids (TSS); pH; total titratable acidity (TTA); TSS/TTA ratio; ascorbic acid; total soluble sugars; anthocyanins and phenolics. The analyses showed that the shelf life of the CCP 76 peduncle clone is 18 days while that of the END 183 clone is of 28 days, both with slight loss of mass, firmness and total anthocyanins.

A fabricacao de biscoitos constitui setor substancial da industria de alimen- tos, ja e consolidado em todos os paises industrializados e esta se expandin- do mundialmente. A producao de biscoitos abastece tanto o mercado interno brasileiro quanto o externo, exportando para cerca de 120 paises (BACK, CA- MARGO, ALBANO, 2012; BRAZILIAN BISCUIT, 2010).
