Okara, a by-product of soybean (Glycine max L.) processing, is rich in nutrients, including proteins, fibers, lipids, minerals, and bioactive compounds. However, its high moisture content (70–80%) makes it susceptible to spoilage. This study investigated the effects four drying methods (using equipment such as conventional electric oven, microwave forced air convection homemade dehydrator) on color, microbiological safety, nutritional composition, percentage yield, technological properties...
The use of colorants in products animal origin is justified by the improvement color foods since this attribute considered a quality criterion. These additives can be produced using industrial effluents as substrates and appropriate organisms, such Rubrivivax gelatinosus. Oxycarotenoids represent class carotenes responsible for pigmentation animals vegetables. R. gelatinosus grows fish industry effluent with resulting production bacterial biomass containing oxycarotenoids. purpose study was...
Rhodocyclus gelatinosus R1 grew photoautotrophically in poultry slaughterhouse wastewater inside glass columns (90x670 mm) during 7 days at 31 ± 4ºC, under anaerobiosis and lightness supplied by daylight plus 3 (100W) incandescent 4 (40W) fluorescent lamps. The culture was centrifuged (4,500xg/20 min) lyophilized to originate a bacterial biomass with 7.1% moisture content. Chemical composition investigation showed 67.6% crude protein, 27.6% total carbohydrate, 0.6% lipids 4.2% ash (dry...
O objetivo deste experimento foi avaliar a influência da variação do nível de energia metabolizável na dieta frangos corte, associada uma proporcional densidade nutricional ração, sobre o desempenho das aves e composição fração lipídica carne. Foram avaliados separadamente machos fêmeas linhagem Cobb 500. Para análise desempenho, utilizado um delineamento inteiramente casualizado em esquema fatorial 6x3, sendo seis níveis ração (2.800, 2.900, 3.000, 3.100, 3.200 3.300kcal kg-1) três idades...
The effects of Rubrivivax gelatinosus biomass inclusion in diets Dekalb White laying hens were assessed. traits studied yolk colour, consumer preference and hepatic renal function. Broken-line regression was used to assess the requirements for colour attributes. Hens fed one six experimental formulated with bacterial at 0 (control), 1.5, 3.0, 4.5, 6.0 7.5 g/kg into a corn–soybean meal basal feed 30 days. All tested concentrations caused darkening increased redness yolks but did not affect...
O objetivo deste trabalho foi avaliar o efeito da utilização de óleo linhaça, em substituição ao soja, sobre a produtividade e qualidade carne frangos corte ambos os sexos. Foram utilizadas 320 aves, um arranjo fatorial 4x2 - quatro combinações dos períodos fornecimento soja linhaça dois sexos repetições. desempenho produtivo avaliado por pesagens ração das aves com 1, 21, 42 dias no momento do abate, aos 49 idade. Após rendimento carcaça sua composição: cortes, vísceras gordura abdominal....
O Brasil é o maior exportador e terceiro produtor mundial de carne frango. A fim manter a competitividade, setor produtivo deve estar sempre alerta às exigências dos consumidores preocupação com bem-estar animal uma tendência crescente. Aspectos envolvendo são particularmente críticos no abate frangos corte. Este estudo avaliou insensibilização em câmara atmosfera enriquecida CO2 para reduzir estresse das aves, comparação elétrica cuba d’água, método atordoamento mais usual frangos. Foi...
Four cultures of photosynthetic bacteria isolated from poultry slaughterhouse wastewater were identified as Rhodocyclus gelatinosus based on the following properties: reddish color in synthetic medium, presence motility, slightly curved Gram-negative rods morphology, gelatin liquefying activity, utilization citrate carbon source and production bacteriochlorophyl a carotenoids spirilloxanthin alternative series. R. may represent nutrients pigments with application feed.
Biomass of the photosynthetic bacterium Rhodocyclus gelatinosus was used at different levels in laying hens' rations as a xanthophyll source. Sixty-four hens were experiment that investigated effects biomass concentrations on weight gain, egg production, weight, and yolk color compared with control group received no supplementation ration. Yolk scored by means fan. All tested able to provide scores higher than those provided group. The pigment deposition began after 24 h administration...
The color of the egg yolk depends on absorption and deposition carotenoids in hen diet represents a visual characteristic great effect product acceptance. Corn is commonly used as an energy value ingredient for formulations, but its pigmenting potential should also be considered color. objective this research was to optimize proportions between yellow red corn-based rations provide maximization yolk's For our study, Dekalb laying hens were individually allotted cages receive 15 experimental...
Brazil stands out in the ranking of broiler chicken production, holding positions world's largest exporter and third producer, scores that demand continuous attention to market requirements with regard product quality, including search for alternative sources feed ingredients. This research's goal was examine effects using Rubrivivax gelatinosus biomass broilers on proximate composition, cholesterol content, fatty acid profile meat cuts. Two hundred Cobb 500 male chicks were randomly...
The proteins recovered by ultrafiltration (UF) represent a co-product of fish industrialization and can be used as protein ingredient in the fortification food formulations. objective this study was to evaluate quality surimi fishburger elaborated with UF from wastewater generated production surimi. water washing operations trims farmed tilapia (Oreochromis niloticus) were filtered 30 kDa polyethersulfone membrane. dehydrated spray dryer added at 5 10% into fishburgers made evaluated for...
We evaluated the influence of dietary inclusion corn gluten meal, apocarotenoic acid ethyl ester (APO-EE), canthaxanthin, and Rhodocyclus gelatinosus R1 biomass on broiler carcass color. These oxycarotenoid sources were used as pigment supplements to a basal ration containing yellow sole source xanthophylls. Objective color values L (lightness), C (chroma), h (hue) measured skin meat surfaces carcasses. On both surfaces, R. oxycarotenoids enhanced chroma (color saturation), compared...
Foi avaliado o efeito da utilização de óleo linhaça na ração, em substituição ao soja diferentes proporções, e vitamina E, até nível 400mg/kg sobre desempenho a composição carcaça frangos corte. O produtivo foi com base pesagens das aves ração aos 21 49 dias idade. No 49º dia, as foram abatidas, os rendimentos dos principais cortes comerciais porcentagem vísceras gordura abdominal avaliados. A fração oleosa forma geral, não interferiu nos parâmetros avaliados (P>0,05). Os machos...
This research aimed at studying the effects of different washing conditions (distilled water x distilled + NaHCO3 NaCl) and cryoprotectants (NaCl saccharose sorbitol sodium tripolyphosphate) for production tilapia surimi. The experiment used a factorial design 2 variables analyzed were proximate composition, non-nitrogen protein (NNP) removal, texture, color yield. moisture contents surimi influenced neither by washings nor cryoprotectants, while ash content was higher when NaCl as yield...

A carne de capivara tem conquistado espaço no mercado carnes exóticas, justificando estudos que auxiliem conhecimento suas características e aperfeiçoamento do seu processo obtenção. Com esse objetivo, neste trabalho, os músculos Longissimus dorsi Semimembranosus provenientes animal macho, com idade entre 12 18 meses, foram submetidos a procedimentos analíticos visando avaliar comportamento quanto aos aspectos tecnológicos. apresentou um baixo teor gordura, 0,4% 0,3% para L. Semimembranosus,...
A padronização da textura é um dos principais problemas relacionados à qualidade carne bovina. Por isso, a avaliação objetiva maciez, por métodos mecânicos, vem sendo estudada há muitos anos. Para que instrumental seja uma ferramenta efetiva nos estudos envolvendo maciez carne, necessário minimizar as causas de variação envolvidas na análise. Atualmente, força cisalhamento Warner-Bratzler o método mais amplamente empregado para essa finalidade. O protocolo padrão dessa técnica analítica...
