| The objective of this study was to evaluate the nutritional value, the oxidative stabilitiy, and consumer acceptance of cakes containing four different concentrations of flaxseed flour (5, 15, 30 and 45%) as partial replacement for wheat flour. The oxidative stability of polyunsaturated fatty acids was evaluated through the lipid peroxidation test (TBARS) in the flour and cakes. Linolenic acid was determined by gas chromatography as well as contents of protein, lipid, ash, and dietary fiber. Consumer acceptance was assessed using a structured hedonic scale of nine points. The oxidative stability of lipid flaxseeds was not affected by the heat treatment during flour processing and cake baking. Cakes made with 5, 15, and 30% of flaxseed flour, the most... |

| AbstractThe Atlantic Forest has species of native fruits, consumed fresh and processed, which have an important contribution to food sovereignty of families that consume it. This study examined the physical and physicochemical characteristics, proximate composition, concentration of carotenoids, vitamin C, vitamin E and minerals in the pulp and kernels of fruits of licuri (Syagrus coronata (Mart.) Becc.). Titratable acidity was analyzed by volumetric neutralization, soluble solids by refractometry, proteins by the micro-Kjeldahl method, lipids by gravimetry using soxhlet, dietary fiber by non-enzymatic gravimetry, carotenoids and vitamin C by HPLC-DAD, vitamin E by HPLC-fluorescence, and minerals by ICP-AES. Pulp were a source of Zn (0.95 mg 100–1), a good... |

| Iron bioavailability was evaluated in three mixtures of cereals, seeds, and grains ("Human Ration"): light, regular, and homemade provided to rats. The animals received an iron depletion diet for 21 days, followed by a repletion diet containing 12 mg·kg-1 of iron for 14 days. The hemoglobin regeneration efficiency and the relative biological value did not differ between the light mixture and control group. The iron bioavailability of the light mixture of cereals, seeds, and grains and the control group were 99.99±27.62 and 80.02±36.63, respectively, while the regular and homemade mixtures of cereals, seeds, and grains showed lower iron bioavailability, 50.12±35.53 and 66.66±15.44, respectively; the iron content of the diet with light cereal mixture light... |

| The soybean is a protein source of high biological value. However, the presence of anti-nutritional factors affects its protein quality and limits the bioavailability of other nutrients. The effect of heat-treatment, 150 ºC for 30 minutes, on hulled and hull-less soybean flour from the cultivar UFVTN 105AP on urease, trypsin inhibitor activity, protein solubility, amino acid profile, and in vivo protein quality was investigated. The treatment reduced the trypsin inhibitor activity and urease, but it did not affect protein solubility. Protein Efficiency Coefficient (PER) values of the flours were similar, and the PER of the hull-less soybean flour did not differ from casein. The Net Protein Ratio (NPR) did not differ between the experimental groups. The... |

| Using packaging and labels to lure consumers and to communicate product benefits directly on the shelf is a competitive advantage factor in the food industry sector. The label is especially effective since besides supplying basic details, such as weight, ingredients, and instructions in compliance with governmental regulations, it attracts consumers' attention and the desire to buy and which often becomes synonymous to the brand name. The objective of this study was to obtain detailed information on consumers' attitudes, opinions, behavior, and concepts regarding guava jam packaging using the focus group technique. The results showed that label color and design, packaging type and information, and brand name and price are determinant attributes in the... |

| Objetivou-se caracterizar as propriedades físico-químicas e a correlação entre a textura instrumental e a aceitação sensorial de massas de pizza fortificadas com farinha integral de soja. Foram desenvolvidas formulações contendo 0%, 30%, 50% e 70% de farinha integral de soja. A análise de textura indicou que a adição de 50% de soja elevou (P<0,05) a dureza, gomosidade, elasticidade e mastigabilidade da massa de pizza. Os teores de proteína, fibra alimentar e dos minerais cálcio, zinco, magnésio, potássio, cobre e fósforo foram maiores (P<0,05) com o aumento da concentração da farinha de soja. O conteúdo de lipídio foi maior (P<0,05) na massa de pizza com 70% de farinha integral de soja. A formulação controle e aquela contendo 30% de farinha... |

| O objetivo deste trabalho foi determinar a composição química, estimar o conteúdo de compostos fenólicos solúveis totais e de fitatos, e avaliar a capacidade antioxidante de grãos integrais de gergelim (Sesamum indicum) creme e preto. Amostras de ambos os tipos de grão foram submetidas a tratamento térmico em estufa de circulação de ar a 150ºC por 10 min e trituradas até granulometria de 20 mesh. O gergelim creme apresentou maior teor de lipídios, carboidratos, fibra alimentar solúvel e valor calórico, enquanto o gergelim preto apresentou maior teor de fibras alimentares insolúvel e total. O gergelim preto apresentou teor de compostos fenólicos solúveis totais de 261,9±7,5 mg em equivalente de ácido gálico (EAG) por 100 g de farinha, aproximadamente duas... |
