Abstract This research aimed to assess the properties of biodegradable films prepared with lyophilized myofibrillar proteins (LMP) from fish filleting residues, fatty acids (stearic, palmitic, and caproic), and surfactant (SLS). The films were characterized to assess the effects of adding those components. Adding fatty acids and SLS resulted in more flexible films with higher elongation values compared to the LMP film. The films prepared with 5% stearic acid and 10% SLS and with 10% palmitic acid and 20% SLS had higher tensile strength compared to the LMP film. Solubility reached 100% in the films added with 10% fatty acids with and without SLS. Increasing the concentration of fatty acids and SLS led to less transparent films. Microscopy analysis showed changes in the morphological structure of the films added with fatty acids and SLS, resulting in whitish films when greater SLS contents were used.

Buscou-se avaliar as condições higiênico-sanitárias da dieta branda servida em um hospital geral da cidade de Belém, Pará, através da análise microbiológica de seus componentes (coliformes fecais, Staphylococcus aureus e Salmonella) e dos utensílios, equipamentos e mãos de funcionários (coliformes fecais, Staphylococcus aureus), bem como elaborar um Relatório Técnico de Inspeção da Unidade de Alimentação e Nutrição do hospital, baseado no Anexo II da Portaria 1428 de 26/11/1993, para a implantação das Boas Práticas de Fabricação. Em nenhuma das amostras foi detectada a presença de Salmonella ou Staphylococcus aureus; entretanto, os componentes da dieta, equipamentos e utensílios apresentaram 100% de coliformes fecais, assim como as mãos de duas funcionárias. Os principais pontos observados para o relatório técnico foram: padrão de identidade e qualidade, condições ambientais, instalações e saneamento, equipamentos e utensílios, recursos humanos, tecnologia empregada, controle de qualidade, garantia de qualidade, armazenagem, desinfecção e desinfestação. Através desta avaliação foram constatadas as péssimas condições higiênico-sanitárias da referida Unidade de Alimentação e Nutrição.

The objectives of this work were to evaluate the hygienic and sanitary conditions of a light diet of a hospital in the city of Belém, state of Pará (Brazil), using microbiological analysis of its compounds (fecal coliforms, Staphylococcus aureus and Salmonella) and of utensils, equipment's and employees' hands (fecal coliforms, Staphylococcus aureus), and to provide an inspection technical report of the hospital Food and Nutrition Unit, according to Annex II of the 1428th Regulation (11/26/1993) of the Ministry of Health to verify the implementation of the Good Manufacturing Practices. None of the samples presented Salmonella or Staphylococcus aureus; however, the compounds, utensils and equipments presented 100% of fecal coliforms contamination, as well as two workers' hands. The main points identified for the technical report were: Identity and Quality Standard, Environmental Conditions, Building Maintenance and Sanitary-Conditions, Equipments and utensils, Human Resources, adapted Technology, Quality Control, Quality Assurance, Storage, Disinfection and disinfestation. It was concluded that the evaluated Food and Nutrition Unit presented very bad hygienic and sanitary conditions.
