The objective of this work was to characterize fruits from the Brazilian savanna by means of physical and chemical analyses. The results obtained for araça peel, araça pulp and marolo pulp, respectively, were: moisture (77.03, 80.41 and 70.56 g.100 g-1), ash (0.65, 0.44 and 0.54 g.100 g-1), protein (1.39, 1.87 and 1.99 g.100 g-1), lipids (0.32, 0.33 and 2.36 g.100 g-1), total carbohydrates (90.88 , 78.25 and 24.55 g.100 g-1), total soluble sugars (8.45, 9.99 and 127.4 g.100 g-1), pH (3.76, 3.99 and 4.49), soluble solids (11° Brix, 8.8 °Brix and 21.4 °Brix) and antioxidant potential (16.33, 12.75 and 34.29 discoloration DPPH/100 mL). Calcium was the predominant mineral in araça (490 mg.kg-1 peel and 485 mg.kg-1 pulp) while magnesium was in marolo (350 mg.kg-1). Citric acid was the predominant organic acid in araça (3125 μg.g-1 peel and 881.25 μg.g-1 pulp) and Malic acid was predominant in marolo (76.68 μg.g-1). Therefore, given their nutrient contents, the consumption of these fruits from the savanna should be encouraged. O objetivo deste trabalho foi a caracterização dos frutos do cerrado, por meio de análises físicas e químicas. Os resultados obtidos, a partir da casca de araçá, polpa de araçá e polpa do marolo foram: umidade (77,03; 80,41; e 70,56 g.100 g-1), cinzas (0,65; 0,44; e 0,54 g.100 g-1), proteína (1,39; 1,87; e 1,99 g.100 g-1), lipídios (0,32; 0,33; e 2,36 g.100 g-1), carboidratos totais (90,88; 78,25; e 24,55 g.100 g-1), açúcares solúveis totais (8,45; 9,99; e 127,4 g.100 g-1), pH (3,76; 3,99; e 4,49), sólidos solúveis (11 ° Brix; 8,8 °Brix; e 21,4 °Brix) e potencial antioxidante (16,33; 12,75; e 34,29 descoloração DPPH/100 mL). O mineral predominante no araçá foi o cálcio (490 mg.kg-1 casca e 485 mg.kg-1 de polpa) e na polpa de marolo foi o magnésio (350 mg.kg-1). O ácido orgânico predominante no araçá foi o ácido cítrico (3125 μg.g-1 casca e 881,25 μg.g-1 de polpa) e no marolo foi o ácido málico (76,68 μg.g-1). Portanto, dado o seu teor de nutrientes, o consumo desses frutos do cerrado deve ser incentivado

Pumpkin seeds are considered waste and its composition has high protein content, being feasible for human consumption, also reducing costs in waste treatment. In this work we provided an alternative to reuse the wastes of pumpkin seed applied in cupcakes formulation as a complementary source to wheat flour. Four formulations with different proportions of pumpkin seed flour were investigated. The effects of partial wheat flour substitution were evaluated using the parameters texture, height, diameter, specific volume, color, proximate composition and scanning electron microscopy. The formulations used in this work consisted of a control, prepared with wheat flour and three provided of 25%, 50% and 75% of pumpkins seed flour in partial in partial replacement to wheat flour. The incorporation of pumpkin seed flour influenced products significantly (p <0.05), providing greater texture, cohesion, pH, soluble solids (Brix). According to results, the formulation with 50% pumpkin seed flour was considered the best proportion due to similarities with the formulation of 100% wheat flour besides high protein.

A challenge to the food sector has been the development of new products incorporating co-products from the food processing industry with minimal impact on their pre-determined structures and adding nutritional quality. In order to add value and develop alternatives for the use of co-products generated during the agroindustrial processing, this work aimed to study the stability of gluten-free sweet biscuits developed with soybean okara, rice bran and broken rice. The formulations were elaborated with increasing percentages of these ingredients and compared with the standard (commercial sweet biscuit) for ten months. The analyses were: weight, diameters (internal and external), thickness, specific volume, instrumental parameters of color, texture, scanning electron microscopy, water activity, proximal composition and isoflavones. The experimental sweet biscuits had characteristics of color, weight, volume and diameters (internal and external) very similar to the commercial, whereas texture, lipids and energy value decreased, and aw, moisture and protein increased during storage. The sweet biscuits showed the same stability when compared to the standard, and the

The objective of this study was to add value to araça and marolo fruits by developing jams and verifying changes in their physical, chemical, and microbiological parameters during storage. The analyses were carried out every 2 months. From the results, it was shown that the levels of moisture (35.89 - 26.34%), lipids (0.43 - 0.27%), sucrose (30.62 - 28.98%), total pectin (0.83 - 0.50%), soluble pectin (0.52 - 0.38%), total phenolic compounds (180.31 - 135.52 mg.GAE 100 g-1), and organic acids (401.1 - 68.5 µg.g-1 citric acid) decreased during storage. However, the levels of protein (0.83 - 0.95%), carbohydrate (62.52 - 72.5%, calories (257,11 - 295,931 kcal), fiber (0.72 - 1.4%), total soluble sugar (62.52 - 70.44%), reducing sugar (32.05 - 41.41%), soluble solids (68.4 - 72.18 °Brix), consistency (0.33 - 0.44 N), total antioxidant potential (11.3 - 22.63%), and color (a* 7.56 - 9.49, and b* 8.63 - 10.49) increased during 1-year storage. The quality of the fruit jams studied was in accordance with the microbiological standards established by the Brazilian legislation. It was concluded that the mixed araça and marolo jam can be stored for 1 year without the addition of additives.

The objective of this work was to characterize promising fruit crops and to explore opportunities for the sustainable and commercial use of flours obtained from fruits as an ingredient in snack bars. The fruit selected was Jeriva, which grow from north to eastern Brazil, and can be found in the Savanna biome. The fruit flour was obtained from dehydrated pulps and the proximate composition, dietary fiber, vitamin C, % scavenging free radicals, mineral composition, pH, ºBrix, titratable acidity and sensory analysis were determined. The flour was incorporated into the formulation by partial substitution of the standard ingredients of snack bars. The presence of increasing amounts (up to 20%) of Jeriva fruit flour resulted in sensory accepted snack bars, with 7.02 average in the scores evaluated, without significant differences among the formulations and significantly increased the protein at 7.12%, vitamin C 40.81 mg.g-1 and fiber contentes showed values at 6.66% for dietary fiber. Moreover, the results of free radical scavenging confirmed the greater antioxidant activity proportional to the increment of flour. Therefore, Jeriva fruit flour could be an alternative sensorily acceptable, for obtaining of snack bars
