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 also found in the azuki beans, and they are very important mainly due to their function as cofactors in metabolic reactions. Phenolic compounds and flavonoids corroborated with other studies and contributed to the antioxidant activity. The principal components multivariate analysis allowed distinguishing the cultivars, and the two principal components could explain 92.28% of data variance.

Food bars are consumed heavily, especially because of their practicality; however they cannot be ingested by celiac patients and present low contents of essential nutrients. The goal of this study was the development and physical-chemical, nutritional and sensory evaluation of a gluten-free food bar containing amaranth and linseed. Gluten fractions were not detected in the food bar formulations. Crude protein and total lipid contents ranged from 68.32 to 76.60 and 74.56 to 82.06 g kg-1 of food, respectively. The polyunsaturated/saturated and n-6:n-3 fatty acid ratios ranged from 0.45:1 to 0.55:1 and 1.44:1 to 2.50:1, respectively. Calcium, magnesium, copper, iron, manganese and zinc were the principal minerals. Application of multivariate analysis enabled sample B to be distinguished according to its mineral and alfa-linolenic acid content. All food bar formulations had good sensory acceptance and high purchase intent.

The aim of this study is the provision of informations regarding the antioxidant molecules content in methanolic extracts of ten fruits through the correlation of total phenolic compounds with antioxidant capacity. The former was determined through the Folin-Ciocalteu assay while the latter was measured by the DPPH· radical inhibition method. It was verified that the fruits possess positive correlation (R2 = 0.6169) of total phenolic compounds in their compositions. Among the analyzed fruits, jambul and acerola showed the greatest values of antioxidant capacity (20.94 and 24.48 mg mL-1) and total phenolic compounds (635.32 and 675.73 mg gallic acid equivalent/100 g of sample). The results that were obtained in this study are useful for consumers, nutritionists and institutions which formulate food policies.

The effects of slaughter weight (28, 32, 36, and 40 kg) on muscle composition and fatty acid profile were determined in an experiment using samples of the Longissimus dorsi (LD) of 20 ram lamb (½ Bergamacia and ½ Corriedale). Mean weight was 12.1 ± 1.05 kg at the beginning. Lambs were fed with a mixture of 30% corn silage, 35% soybean meal, 34% oat hay, and 1% vitamins and minerals, ad libitum. Samples of Longissimus dorsi muscle were analyzed for their content in moisture, ash, crude protein, total lipids, and fatty acid profile. Oleic acid (18:1n-9) was in greater concentration than other fatty acids in all samples investigated. The concentration of saturated fatty acids (SFA) increased (p < 0.05) with an increase in slaughter weight, while monounsaturated and polyunsaturated fatty acids (PUFA) decreased. Lambs slaughtered at either 28 or 36 kg had an n-6/n-3 ratio (2.9 and 2.85, respectively) close to the recommended for humans (4.0 maximum). The overall results showed that slaughtering lamb at 28 kg resulted in the best meat quality as shown by nutritional indexes for humans (PUFA/SFA and n-6/n-3 ratios) and concentrations of crude protein (16.02%) and total lipids (13.24%).

Os cordeiros com peso médio inicial de 12,1 ± 1,05 kg foram alimentados com uma mistura de 30% silagem de milho, 35% farelo de soja, 34% de feno de aveia e 1% de vitaminas e minerais, ad libitum. As amostras de Longissimus dorsi foram submetidas as análises de umidade, cinza, proteína bruta, lipídios totais e perfil de ácidos graxos. O ácido graxo majoritário em todas as amostras foi o oleico (18:1 n-9). A concentração de ácidos graxos saturados (AGS) aumentou (p < 0,05) com o peso de abate, enquanto os monoinsaturados e poli-insaturados (AGPI) diminuiram. Os cordeiros abatidos com 28 e 36 kg apresentaram razão n-6/n-3 (2,9 e 2,85, respectivamente) dentro das recomendações para humanos (máximo 4,0). Os resultados globais mostram que o abate de cordeiros com 28 kg resultou em melhor qualidade da carne como demonstrado por índices nutricionais para uso humano (AGPI/AGS e razão n-6/n-3) e concentrações de proteína bruta (16,02%) e lipídios totais (13,24%).

The fatty acid profile of the carcass of Nile tilapia (Oreochromis niloticus) fingerlings fed diets enriched with different soybean, canola, sunflower, flaxseed, rice, and corn oils was examined. The results showed that palmitic (16:0), stearic (18:0), oleic (18:1n-9), linoleic (18:2 n-6), and linolenic (18:3 n-3) acids were the predominant fatty acids in all vegetable oil, diet, and fish carcass samples analyzed. Flaxseed oil presented the highest amount of linolenic acid (45.63%), while the other vegetable oils had percentages lower than 5.0%. Neither of the vegetable oils used affected the performance of tilapia fingerlings and they can be utilized in Nile tilapia fingerling diets. However, in relation to the carcass fatty acid profile, the use of flaxseed oil in Nile tilapia fingerling diet is recommended. Foram examinados o perfil de ácidos graxos nas carcaças de alevinos de tilápia do Nilo (Oreochromis niloticus) alimentados com dietas enriquecidas com diferentes óleos vegetais (soja, canola, girassol, linhaça, arroz e milho). Os resultados indicaram que o ácido palmítico (16:0), esteárico (18:0), oléico (18:1n-9), linoleico (18;2n-6) e linolênico (18:3n-3) foram os ácidos predominantes em todas as frações analisadas (no óleo vegetal, dietas e carcaças dos peixes). O óleo de linhaça apresentou o maior valor de ácido linolênico (45,63%), quanto aos outros óleos vegetais tiveram uma percentagem menor que 5,0%. Todos os óleos vegetais não afetaram a performance dos alevinos e podem ser utilizados nas dietas, entretanto, em relação a qualidade nutricional o uso do óleo de linhaça é recomendado em dietas de alevinos de tilápia.
