| The present work evaluated and compared the lipid oxidation of charque, taken from, the semi-tendinosus muscle of animals from the Nelore breed (Bos taurus indicus), supplemented with α-tocopherol. Charque was produced submitting the samples to salt moisture, salt drying and exposition to the sun for dehydration until water activity values (Aw) reached 0.75. The statistical analysis of the results showed that there were no significant differences in the values of cholesterol, total lipids, fatty acids and substances relative to tiobarbituric acid (TBARS) and tocopherol as the samples were controlled and supplemented, respectively. Despite this, the values of TBARS and cholesterol were lower in the samples with the supplement of α-tocopherol. The... |

| Os folatos compõem uma classe de vitaminas redescoberta nas últimas décadas pela sua importante associação com diversas funções, nos vários processos metabólicos no organismo humano. As principais fontes descritas na literatura são os vegetais, os cereais e as leveduras. Objetivou-se quantificar o 5-metiltetrahidrofolato (5-metilTFH) em vinhos durante o processamento e conservação. Foram coletadas amostras de vinhos tintos das variedades viníferas Cabernet Sauvignon, Merlot e Pinot noir, e das não viníferas Isabel (tinta) e Niágara (branca) na colheita, no final da fermentação alcoólica, e maloláctica e seguindo-se aos 4, 7, 12 e 24 meses de conservação a partir do início da fermentação. A técnica de Cromatografia Líquida de Alta Eficiência (CLAE) foi... |

| The characterization of wine samples by direct insertion electrospray ionization mass spectrometry (ESI-MS), without pre-treatment or chromatographic separation, in a process denominated fingerprinting, has been applied to several samples of wine produced with grapes of the Pinot noir, Merlot and Cabernet Sauvignon varieties from the state o Rio Grande do Sul, in Brazil. The ESI-MS fingerprints of the samples detected changes which occurred during the aging process in the three grape varieties. Principal Component Analysis (PCA) of the negative ion mode fingerprints was used to group the samples, pinpoint the main changes in their composition, and indicate marker ions for each group of samples. |

| 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... |

| A amora-preta (Rubus sp.) é uma fruta cuja exploração comercial está iniciando no Brasil. Seu cultivo iniciou na década de 70 e vem aumentando com a introdução e adaptação de novas cultivares. Porém, pouco se conhece sobre as disparidades geradas na composição e nas características das frutas dessas novas plantas. O objetivo deste trabalho foi avaliar as características físico-químicas de diferentes cultivares ('Tupy', 'Guarani' e 'Cherokee') e seleções (02/96, 07/001 e 03/001) de amora, que estão sendo estudadas para originar cultivares adaptadas à região Sul do Brasil. Foram analisados a cor objetiva, sólidos solúveis (SS), pH, acidez titulável, composição centesimal e ácidos graxos de amoras. As frutas apresentaram umidade entre 84,8 e 90,3%; proteína... |

| Food industry generates a significant amount of seed wastes from the juice production, frozen pulps and jams. Considering that the characterization of wastes is the first step to determine their potential use, the aim of the present study was to determine the composition and the antioxidant capacity of seeds from pitanga fruits with different flesh colors (purple, red and orange). Chemical composition results revealed that pitanga seeds are a good source of insoluble dietary fiber, with low protein and fat levels, and no relevant differences were found among pitanga seeds from different flesh colors. Pitanga seed extracts had powerful antioxidant capacity that was partially correlated to their high phenolic content and showed some variation according to... |
