| ABSTRACT Free films of pullulan-polymethacrylate associations were produced by casting process to develop a novel target-specific material. For characterization, tests of water vapor permeability, swelling index, infrared absorption spectroscopy, thermogravimetric analysis, scanning electron microscopy and mechanical analysis were performed. The polysaccharide concentration directly influenced vapor permeability and swelling, increasing the values of the latter up to five times when added in a proportion of 20% (per weight). The individual properties of each polymer were maintained, and chemical interactions were not detected. The films were found to be thermally stable and they had unaltered mechanical properties with the addition of the polysaccharide.... |

| The aim of this work was to perform the microbiological and physicochemical characterization of surimi made from waste of piramutaba filleting. The results of physicochemical characterization of the waste and surimi were: moisture (76.37 and 79.11%), total lipids (5.35 and 0.74%), proteins (14.92 and 10.79%), ash (3.03 and 2.35%), pH (6.9 and 7.4), caloric value (109.15 and 77.86 kcal.g-1), and water activity (both 0.98), respectively. The results of the levels of total volatile bases were 7.29 mgN/100-1 g (waste) and 7.01% carbohydrate (surimi). The values of total lipids and proteins were reduced during the preparation of surimi, probably due to successive washes during the processing. Waste and surimi were examined microbiologically and are in... |

| The objectives of this study were to physicochemically characterize and determine the antioxidant activities and anthocyanin contents of organic Rabbiteye blueberries grown in Southern Brazil and its derived products, in order to investigate the utility of food processing wastes as raw materials for developing products with beneficial health properties. The antioxidant capacity of the blueberries was superior to that of other fruits and juices. The pomace exhibited high activity, albeit lower than that of the fruit, while the flour and the dried blueberries lost 66% and 46% of the original antioxidant activity, respectively. The average anthocyanin contents of the fruits were moderate compared to other sources and species of blueberries. The pomace... |

| 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... |
