Avaliação físico-química e sensorial de fermentado de acerola

Fruit processing for beverage production purposes is a way of adding value to the raw material and of raising the farmer s income by increasing the demand. Thus the objective of this work was the production of fermented West Indian cherry beverages and their physicochemical and sensory evaluation. The beverages were produced based on the Brazilian legislation for fermented fruit beverages and wine. The fermented beverages were produced from West Indian cherry pulp (pulper) and juice (press) and sweetened with sugar to obtain three types of beverage: dry, semidry and sweet. The beverages were submitted to the following physicochemical analyses: pH, alcohol, reducing sugars, total reducing sugars, total acidity, volatile acidity, fixed acidity, dry extract, reduced dry extract, alcohol to reduced dry extract ratio, free sulphur dioxide, total sulphur dioxide and turbidity. In the sensory analysis, the beverages were assessed using a 9-point hedonic scale, evaluating the attributes of appearance, odour, flavour and overall assessment. The chemical and sensory results were submitted to an analysis of variance and the means compared using Tukey s test (5%). Both the raw materials (pulp and juice) and the different sugar concentrations (dry, semidry and sweet) interfered in the sensory and physicochemical parameters of the fermented West Indian cherry beverages, the tasters showing preference for the sweetened beverages.

Padronização e melhoria de processos produtivos em empresas de panificação: estudo de múltiplos casos

An important tool for organizational change is the standardization of procedures for developing standards so that companies have greater control, thus providing a broad view of their processes and needs. This paper presents and analyzes a model of standard processes developed by the bakeries in PROPAN (Support Programme Bakery), detailing each stage of deployment to evaluate both its benefits for companies and employees and its shortcomings, to make proposals for improvements. Five bakeries were selected for this multi-case study, whose methodology consists of qualitative research using semi-structured interviews, on-site observations and document analysis. The main positive points of the model are the possibility of standardized recipes and procedures, a large decrease in wasted raw material and a significant increase in worker productivity. The main challenges are the lack of employee and owner commitment to the project, the lack of materials needed for deployment and the resistance of employees to change.

Biofertilizante bovino, cobertura morta e revestimento lateral dos sulcos na produção de pimentão

The adoption of management practices that reduce water losses is essential to conserve moisture and improve soil temperature, especially in arid and semiarid environments of the Brazilian Northeast, characterized by high evapotranspiration and the adoption of irrigation with saline water, which harms growth and yield of commercial crops. Given these factories, an experiment was conducted in Nova Floresta, Paraiba, from August 2010 to February 2011 in Oxisoil, in order to evaluate the production of bell pepper and soil moisture in grooves with side trim, and application of biofertilizer and mulch cattle. The experimental design was randomized blocks with four replications using a factorial 2 x 2 x 2 for the ground beef with and without biofertilizer, with and without residues of sisal fiber (Agave sisalana), with and without the side facing the grooves, to reduce lateral water losses by infiltration of water with polyethylene plastic film. From the results, the lining of the lateral grooves provided higher values of soil moisture, number of fruits, fruit mass, plant production and productivity, bell pepper plants. It was also found that the combination of biofertilizer and mulch the ground beef remained wetter in the first 15 cm depth.

Cleaner Production initiatives and challenges for a sustainable world: an introduction to this special volume

This special volume of the Journal of Cleaner Production is comprised of articles presented at the 3rd International Workshop Advances in Cleaner Production held in Sao Paulo, Brazil, in 2011. The content underscores the recognition of the pressing and inescapable need for making changes from unsustainable to sustainable production and consumption patterns. The 48 articles from 15 countries provide different, but complimentary approaches to help industrial and societal sectors in advancing on their paths towards sustainability. Initiatives and challenges are included, which systematically address problems affecting raw material changes, technological modifications, product and policy changes. The findings range from proposals for alternative uses of wastes, substitution of raw materials for environmentally friendlier substances, optimization of industrial processes by source reductions of wastes and emissions and documented economic and environmental advantages of a wide array of initiatives. The roles of operational and managerial practices are also stressed, highlighting the role of diverse stakeholders as promoters of implementation and internalization of innovative cleaner technologies within companies. Systemic assessment tools are employed and experimented with in order to more effectively evaluate the environmental performance of systems on the biosphere scale. The methodological procedures and proposals presented can help in the design and management of production systems, for governmental and corporate policy development, for implementing and monitoring CP Programs, prevention and mitigation strategies, and evaluation of the outcomes of CP initiatives in the production and service sectors.
