Determinação do valor energético em bebidas de maracujá

The objective of this work was to calculate the energetic values in passion fruit commercial beverages (whole juices, reconstituted juices, tropical juices, and nectars) by their centesimal composition. Then, the energetic values were compared to the caloric values as described on the nutritional facts from the beverageslabels. Analyses of moisture, protein, lipids, ashes, and carbohydrates were done in 25 commercialbeverages samples. In order to calculate the energetic value of each sample, the following conversion factors were used: 4 kcal.g-1 for carbohydrates, 4 kcal.g-1 for proteins and 9 kcal.g-1 for lipids. To allow the comparison of the results, the energetic values printed on the labels were converted into kcal.100g-1 usingthe beverages density. Overall, the commercial beverages calculated energetic values were similar to the nutritional facts.

Suco integral de amora (Morus nigra L.) obtido através de prensagem e despolpamento: rendimento e caracterização físico-química

Mulberry (Morus nigra L.) is a fruit with a great potential for technological uses, which could be employed to manufacture of syrups, ice cream, candies, yoghurts, beverages, jam, etc. Only the leaf from mulberry trees is commercially used for silkworm feeding. This tree is cultivated on many agricultural environments such as small rural proprieties and settlements. Small farmers waste a great amount of their production for not knowing about mulberry technology. Thus, the objective of this work was to access extraction yield and physical-chemical properties of mulberry whole juice from ripe, green and a mixture of both by using press and depulper. Statistical analysis of results was carried by media and standard deviation calculations. 173 kg of mulberry were picked being 49.31% ripe and 50.68% green. Press delivered greater extraction yield of whole juice (80.50% to 81.60%) when compared to press (71.43% to 77.50%). Whole juice obtained from both equipments has shown the following values: soluble solids 7.45% - 12.11%, titrable acidity 0.45 – 1.23%, ratio 6.03 – 26.84, pH 3.69 – 4.35, total reducing sugar 4.05% – 9.96%, reducing sugar 3.95% - 9.15%, sucrose 0.00% - 0.04%, turbidity 221.25 NTU - >4,000 NTU. Whole juices obtained from both equipments has shown similar physical-chemical characteristics except turbidity. The authors concluded that press was the best extraction equipment due to its greater yield and whole juice quality regarding turbidity

The current competitive market requires companies to adapt so that they can meet the needs of customers in an agile manner and aimed at the lowest possible cost in their manufacture, be it a product or service. The Toyota Production System is aimed at higher profits through lean manufacturing practices with reduced spending, smaller lots and inventories, generated by market demand. The variety of products makes the setup of the equipment a critical point and it should be reduced as much as possible so it does not affect productivity. The rapid exchange of tools allows with few actions and a modification that time does not exceed one digit on your total time. In this study, a case study showed that only with standardization and use of cheap improvements made it possible to reduce setup time in bottle labeling machine by 98 minutes for a final time of approximately 10 minutes with little investment, demonstrating the feasibility the displayed and a monthly gain tool in bottles at approximately 120,000, generating a performance gain and budget of approximately R$ 94,000.00 per month

Avaliação do desempenho ambiental e racionalização do consumo de água no segmento industrial de produção de bebidas

A região Amazônica, detentora de grande potencial hídrico, tem atraído indústrias que promovem uso intensivo de água, por isso, existe uma emergência por instrumentos que administrem essa tendência. Neste trabalho foi diagnosticado o nível de racionalização do uso da água pelo setor industrial de produção de bebidas no estado do Pará, assim como as causas do comportamento do setor. As variáveis dependentes (de comportamento) foram classificadas de acordo com quatro dimensões (gestão ambiental, manejo da água, manejo dos efluentes e medidas avançadas de racionalização) que compõe o nível de racionalização da gestão industrial hídrica. As variáveis independentes foram associadas ao: porte, ramo, tipo de embalagem utilizada, disponibilidade hídrica e valor econômico da água. Os dados levantados mostraram que a produção de bebidas tem uma grande pegada hídrica operacional total (acima de) 15.250 m³/dia, com as pequenas empresas apresentando o maior consumo relativo por unidade produzida (maior que 7 L de água/L de bebida). O setor como um todo apresenta baixo nível de racionalização do uso da água, a dimensão mais eficiente é a de gerenciamento da água; entretanto algumas medidas avançadas podem ser visualizadas, especialmente a recirculação da água em torres de resfriamento. A análise das variáveis de estudo demonstra que o nível de racionalização é dependente diretamente do ramo e do porte da empresa. Conclui-se que o consumo tende ao desperdício; em resposta a este quadro, devem ser priorizadas políticas públicas voltadas para internalização dos custos ambientais embutidos no processo.

Cambios en la distribución minorista de alimentos y bebidas en Argentina 2001-2003 : Hacia nuevas horizontalidades territoriales

Se presentan en este trabajo los principales cambios en la distribución minorista de alimentos y bebidas en la Argentina iniciados con la crisis económica, política y social del año 2001. El territorio usado por parte de los actores sociales involucrados, como las empresas de diferentes tamaños (desde hipermercados a almacenes), y las personas (consumidores), ya no solo responderá a un orden global y a verticalidades territoriales, sino que muchas de estas nuevas tendencias estarán comandadas por normas locales relacionadas con la horizontalidad territorial. Entre estos cambios, son los más importantes: el consumo orientado a las ofertas; a empaques más chicos; a segundas y terceras marcas; a marcas propias de supermercados; a una nueva frecuencia en la realización de las compras; a la combinación de varios canales de distribución con el fenómeno denominado "vuelta al barrio", y a compras de productos sueltos.
