A contaminação dos alimentos servidos nos hospitais pode ocorrer durante o preparo, transporte, armazenamento e administração. As fórmulas infantis à base de leite são produtos, líquidos ou em pó, destinados à alimentação de crianças ou recém-nascidos quando não puder ser utilizado o leite materno ou humano. No hospital, essas fórmulas são geralmente manipuladas no lactário ou em Unidades Centralizadas de Produção terceirizadas. A manipulação de fórmulas infantis deve receber atenção especial considerando que os pacientes a quem são destinados são, geralmente, mais suscetíveis a infecções, a desidratação e suas conseqüências. O objetivo do estudo consistiu em avaliar a carga microbiana de fórmulas infantis segundo parâmetros da RDC 63 e RDC 12 em diferentes intervalos de tempo e faixas de temperatura por até 40 horas após o preparo. Os resultados mostraram que fórmulas preparadas em condições higiênicas sanitárias adequadas garantem a qualidade final das formulações por até 40 horas após o horário de preparo, quando mantidas sob-refrigeração com temperaturas entre 2 a 80 C. E, as formulações podem ficar até 6 horas à temperatura ambiente média de 23 a 250 C. Podemos concluir que este estudo ratificou a necessidade da aplicação efetiva de pré-requisitos higiênico-sanitários utilizados durante a cadeia produtiva de preparo das fórmulas infantis para lactentes resultando em um produto seguro do ponto de vista microbiológico.
Recycling of lignocellulosic agro-industrial residues waste is the key of the environmental sustainability. So, the goal of the present study was to utilize artichoke (Cynara cardunculus L.) bracts as a potential source of bio-active compounds or as a carbon source during bio-production of ethanol and to evaluate its nutritive value for livestock feeding by using in vitro gas production technique. The chemical composition, phenolic compounds, and radicals scavenging property of extracts were determined. Silage production and acid hydrolysis on conversion of lignocellulosic artichoke was studied. Also, the acid hydrolysate of lignocellulosic components as a carbon source was investigated during bio-production of ethanol using Saccharomyces cerevisiae and simultaneous saccharification fermentation process. The obtained results revealed variation in proximate composition and mineral content among treatments of artichoke bracts used here. The blanching processing of artichoke bracts had higher total phenolic content (935.43 mg GAE /100 g DW) and 89.64% inhibition of DPPH radical with an IC 50 value of 6.23 mg/ml. The highest reducing sugar content was obtained by using sulphuric acid (3%) for 20 min at 120°C. Fermentation of the hydrolysates gave the highest ethanol yield of (10.02 g/L), which corresponds to volumetric productivity of ethanol being 1.52 g /L/h with fermentation efficiency of 97.39% and biomass of 4.64 g/L after 48 hr. The results of the present study suggest that adding sugar beet molasses to the fermentation medium enhanced production of bio-ethanol (14.01g/L). The results also showed that the nutritional value of the artichoke bracts is similar to that of good roughage as hay in terms of metabolizable energy (8.42 MJ/kg DM), net energy (3.15MJ/kg DM), short chain fatty acids (99.48 mM), microbial protein synthesis (76.49 g/kg) and organic matter digestibility (63.41 %).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
