Aproveitamento de sementes de abóboras (Cucurbita sp) como fonte alimentar

Brazil processes much of its fruit by producing natural juices, candy preserves, extracts and pulps; however, almost 60% of their total weight derives from peels, leaves and seeds. As a result, the emphasis lies most strongly on the use of waste, especially waste that is not commonly used by the food industry or by consumers. The use of seeds would increase the viable sources of raw materials, lower operating costs of industries and would promote the development of new food products, since they are our main sources of protein, fat, fiber, functional compounds, vitamins and minerals salts. This paper presents alternatives for the use of pumpkin seeds (Cucurbita sp), which are often underutilized or discarded. It also demonstrates the bioactive and anti-nutritional compounds and their health effects.

Efeito da fermentação fúngica no teor de compostos fenólicos em casca de café robusta

Coffee husk is an abundant by-product generated by the coffee industry and it can be used for the production of-value-added phenolic compounds. Currently, this residue has no commercial use due to the presence of anti-nutritional compounds and it is returned to the soil or burned. The aim of this study was to evaluate the content of phenolic compounds in Robusta coffee husk, the adequacy of this residue as substrate for fermentation processes, as well as evaluating the influence of fungal solid state fermentation to obtain phenolic compounds from this residue. In the present study, the use of different solvents for the extraction of polyphenols was evaluated and the content was found to be in the range of 96.9-159.5 mg of galic acid (GA).g(-1) substrate, depending on the solvent used. The best solvent was acetone, therefore it was selected for extraction. Studies were carried out to evaluate the effect of solid-state fermentation in the release of phenolic compounds, using the filamentous fungi Penicillium purpurogenum. The total phenolic content increased from 159.5 up to 243.2 mg GA.g(-1) substrate as a result the solid-state fermentation.

Exoenzimas em rações de frangos de corte

The study aimed to evaluate performance, relative weight of the small intestine, digestibility and deposition of minerals in the bone of broilers supplemented with enzymatic complex (carbohydrases and phytase) in sorghum-based diets or sorghum and millet. In the experiments based of sorghum and sorghum and millet were used 912 day-old male and female Hubbard Flex chicks (50:50) were distributed in a completely randomized design in a 2x2 factorial arrangement (Feed Control base Sorghum (Contcs); FeedReducedbase Sorghum (RedS); Feed Control base sorghum + Enzymatic Complex (Contcs + Enz);. Feed reduced base sorghum + Enzymatic Complex (RedS + Enz) in the study of feed basis of sorghum and millet the design was similar (Feed Control base sorghum + millet ( ContSM); Reduced feed based on Millet + Sorghum (RedSM); Feed Control based Sorghum + Millet + EnzimaticComplex (ContSM + Enz); Reduced Feed base Sorghum+ Millet + Enzimatic Complex (RedSM + Enz). At 35 and 42 days of age were determined performance data: feed intake (CR), body weight (BW), feed conversion (FC), viability (VIAB), relative weight of the small intestine and deposition of minerals in the bone. The digestibility was evaluated sorghum grain size (crushed and whole) with and without exoenzimatico complex. They used 32 birds, eight birds per treatment, in periods from 17 to 21 (initial) and 31 to 35 days of age (fattening). The exoenzimático complex used in feed favored the weight gain results, feed conversion and bone mineralization when compared to a control diet not added to enzymes, demonstrating its effect on non-starch polysaccharides and phosphorus phytic present as anti-nutritional factors in these diets, increasing the digestibility and supply of metabolizable energy, essential amino acids, methionine and lysine and calcium and phosphorus for bone formation. It is concluded that a safe strategy for inclusion in feed is based on the reduction of energy levels, essential amino acids, methionine and lysine and calcium and phosphorus in the expected result of the constant activity of the enzymes of this exoenzimático complex.
