| Objetivou-se com este trabalho avaliar o efeito das formas de processamento e do alecrim na defumação dos troncos e filés sem pele de tilápia do Nilo sobre o rendimento e as características organolépticas. Independente da forma de processamento aplicada, os filés defumados na presença do alecrim apresentaram menor rendimento. Foi também observado que os filés obtidos a partir dos troncos defumados proporcionaram maiores rendimentos. Analisando a forma de processamento dos filés defumados, os provadores apresentaram maior aceitação para filés (FIL) (2,88) em relação aos filés a partir dos troncos defumados (FTD) (2,63). A presença de alecrim nos filés, independente da forma de obtenção do produto final, não foi significativo para aparência, cor, aroma e... |

| ABSTRACT: This study evaluated the yield, color, and chemical composition of commercial cuts (tail, sirloin cut, back fillet, and thigh) of Pantanal caiman meat in both sexes. The yield of tail was higher than other cuts, and the yield of females (17.0%) was higher than males (15.9%). The thigh of males had lower protein content (20.8%) compared with other cuts. Females showed a higher lipid content in the tail (2.4%) and thigh (0.8%) compared with males (1.7% and 0.4%, respectively). The tail presented the greatest content of monounsaturated fatty acids (45.2%) and higher n6/n3 ratio (4.6). Although lightness was not different among cuts or between sexes, there were differences in color. Males have more yellowish meat compared with females. Thigh and back... |

| Eight Holstein cows with body weight 570 ± 43 kg and 60 ± 20 lactation days were distributed in a double Latin square design with four 21-day periods to determine the effects of feeding ground or whole flaxseed with or without monensin supplementation (0.02% on a dry matter basis) on fatty acid profile of butter stored for 15 and 45 days. Ground flaxseed supply, in comparison to whole flaxseed, reduced relative percentages of 16:0, cis7-16:1, 17:0, and cis10-17:1 but it increased those of cis9,trans11-18:2, cis3-18:3, and omega 3 fatty acids in butter fat, reducing relative percentage of medium-chain fatty acids and increasing the content of polyunsaturated fatty acids. Supplementation with monensin increased relative percentages of cis9,trans11-18:2 and... |

| The objective of this study was to quantify alpha-linolenic acid (LNA, 18:3n-3) of dried wheat leaves, harvested at different development stages (20, 40 and 80 days), to determine the antioxidant potential and the total phenolic compounds of leaves harvested at 80 days, as well as to perform mineral analysis (Na, K, Fe, Ca, Mg, P, Zn, Cu and Mn). It was observed a predominance of polyunsaturated fatty acids (PUFA) compared to saturated fatty acids (SFA) in the lipid fraction of leaves. Leaves collected in all periods presented ratios of PUFA/SFA, omega-6 and omega-3 fatty acids (n-6/n-3) considered suitable for food. The highest content of LNA was found in leaves harvested at 60 days, corresponding to 2.146,72 mg 100 g-1 dried matter. The range time... |

| This study was conducted to evaluate the performance, carcass characteristics and chemical composition of Longissimusmuscle (LM) of the bulls. Twenty-four Nellore bulls were used in a complete randomised design. The bulls were randomly assigned to one of the three diets containing 0, 5 or 12% glycerin. Final BW and ADG were similar (P>0.05) between the bulls fed with 5 or 12% of glycerin but were higher (P<0.10) compared to the bulls fed without glycerin. DMI and feed efficiency was not affected (P>0.05) by glycerin level. Hot carcass weight increased (P<0.10) when glycerin was fed at 5%. Glycerin level did not affect (P<0.05) the dressing percentage and fat thickness. LM increased (P<0.10) when glycerin was fed at 12%. Dietary... |

| The objective of this study was to evaluate the incorporation of omega-3 fatty acids (n-3 FA) on male Swiss mice livers receiving diets based on linseed oil (LO) for up to 56 days. The mice were sacrificed at 7, 14, 28, 42, 56 days and FA concentration was analyzed by gas chromatography. A total of 13 FA were identified on LO feeds presenting alpha-linolenic acid (LNA) contents of 26.97 %. A total 22 FA were identified in the livers of the mice. Part of the LNA was converted into n-3 FA (20:3n-3, eicosapentaenoic acid-EPA, 22:5n-3, and docosahexaenoic acid-DHA), and some of the LNA was stored in the liver. LNA, EPA and DHA concentrations (mg/g total lipids ) from 0 days for up 56 days increased from 1.29 to 18.90 (LNA), 0.20 to 18.90 (EPA) and 41.26 to... |

| ABSTRACT Azuki beans are small red grains rich in several essential nutrients used in traditional dishes in Asia that, nowadays present many applications around the world. This work aimed at evaluating angularis and niponensis cultivars from south region of Brazil. Both cultivars presented proximal composition similar to literature and the majority fatty acids were 18:2n-6, 16:0 and 18:3n-3. All samples showed polyunsatured fatty acids prevalence and nutritional indices and ratios considered adequate for biological system maintenance of a healthy organism. The grains presented significant contents of tocopherols and vitamin E activity, resulting in a high contribution to the dietary reference intake. Significant contents of iron, manganese and zinc were... |

| Abstract: The objective of this work was to analyze the proximate and fatty acid composition of the dorsal and ventral muscles of wild pirarucu (Arapaima gigas) captured from a Brazilian Amazonian lake. Dorsal and ventral muscles were dissected out, freeze-dried, vacuum-packed, and had the proximate and fatty acid composition analyzed. Ash, total proteins, and lipids were inversely proportional to moisture and had higher levels in the ventral muscles. Twenty-seven fatty acids were quantified in both muscles without significant differences between them, except for the heneicosylic, palmitoleic, γ-linolenic, and dihomo-γ-linolenic acids. Saturated and monounsaturated fatty acids were predominant in both muscles. The eicosapentaenoic (EPA) and docosahexaenoic... |

| The objective of this work was to compare the physicochemical characteristics of quinoa and flaxseed bread. Sensory acceptance, color and texture were also appraised. They showed appropriate balances between their content of polyunsaturated and saturated fatty acids and low levels of trans fatty acids. Flaxseed bread had larger amounts of mono and polyunsaturated fatty acids, omega-6 and omega-3, as well as a more balanced omega-6/omega-3 ratio. Quinoa bread, on the other hand, had the advantage of presenting smaller contents of saturated fatty acids. With regard to color and texture, quinoa bread had similar characteristics to the flaxseed bread. The quinoa bread was well accepted by the consumers, who expressed high interest in buying it. |
