| This study was carried out to obtain more information about the physicochemical properties, composition, and antioxidant activity of pitanga fruits (Eugenia uniflora L.), particularly fruits from the State of Rio Grande do Sul, Brazil. Pitanga with different flesh colors (purple, red, and orange) from tree selections cultivated at Embrapa Clima Temperado (RS-Brazil) were analyzed. Only slight differences were observed in the quality parameters and in the proximate and fatty acid compositions among the fruits studied. The extracts from purple-fleshed pitanga had the highest total phenolic and anthocyanin contents along with the highest antioxidant capacity. The antioxidant capacity (DPPH and FRAP assays) of methanolic pitanga extracts was highly correlated... |

| This study investigated the effects of hydroethanolic E. japonica seed extracts (EJSE) as inhibitors of lipid and protein oxidation on fish pates subjected to refrigerated storage. Five fish pate formulations were developed. These formulations included two control pates (water-control and ascorbic acid-control) and three pates with added EJSE (0.1, 0.2 and 0.4g of seed 100g-1 product, equivalent to 3.4, 6.8 or 13.6mg phenolic compounds kg-1 product), which were then stored under refrigeration for 35 days. Conjugated dienes (CD) and peroxide (PV) values increased along with the storage time; however, these values decreased and were similar among all samples at the end of 35 days of analysis (P<0.05). However, the thiobarbituric acid reactive substances... |

| O objetivo do presente estudo foi avaliar o efeito da aspersão de extratos de Lippia alba na estabilidade lipídica de filés de carpa húngara armazenados a -18±2°C. Filés não tratados (controle sem aspersão) ou aspergidos (1mL 10g-1 de filé) com água destilada (controle água destilada) ou com extratos de L. alba (0,10g mL-1) hidrometanólico ou aquoso foram analisados durante o armazenamento nos dias zero, 90 e 180. Independente do tempo de congelamento, o extrato hidrometanólico reduziu os valores de dienos conjugados (DC) dos filés em relação aos demais tratamentos, além de reduzir os valores de ácidos graxos livres aos 90 dias (P<0,05). O extrato aquoso resultou em maior teor de peróxidos após 180 dias de congelamento comparado aos demais tratamentos... |
