Análise Microbiológica de Embalagens para o Acondicionamento de Medicamentos e Cosméticos

Microbiological Control of Packaging Materials for Medicines and Cosmetics. Several consumers and official agencies, associated with the necessity of more efficient, safety and good microbiological quality packaging materials, conducted to the challenge of having packages which assure both the integrity of products and consumer's health. However, the packaging material can be an important source of microorganisms when does not fulfill the microbiological quality requirements. The objective of this work was to study the microbiological quality of different types of packaging materials for medicines and cosmetics. The microbial quality studies were conducted by analyzing representative samples by bioassay. The packing materials were analyzed for microbiological quality to verify presence of viable microorganisms. They showed the analyzed packaging materials for medicines are in agreement with RDC # 481 on 23/9/1999 of ANVISA. However, the packages to store cosmetic material are not fulfilling this RDC. The microbiological quality control of packing materials has fundamental importance for public health.

Postharvest conservation of the tuberous roots of Pachyrhizus Ahipa (Wedd) Parodi

O objetivo deste trabalho foi avaliar o período de armazenamento em diferentes temperaturas e embalagens na conservação das raízes de Pachyrhizus ahipa. As raízes foram colhidas, lavadas e armazenadas em bandejas de isopor, no refrigerador, câmara fria e à temperatura ambiente. As embalagens utilizadas foram PVC, saco plástico e sem embalagem (controle). As bandejas foram retiradas do seu ambiente de armazenamento e analisadas quanto a acidez total titulável, sólidos solúveis totais, pH, teores de cinzas, lipídios, carboidrato total e proteínas em base seca. A menor perda de massa das raízes foi em câmara fria e em saco plástico. A ATT manteve-se maior nas raízes armazenadas em câmara fria e na embalagem de PVC; os menores teores de SST foram observados em câmara fria não variando entre as embalagens. em todos os tratamentos a porcentagem média de carboidratos foi 84,9%. A porcentagem de lipídios foi maior nas raízes armazenadas em temperatura ambiente, entretanto, o teor de proteína e cinzas foram maiores nas armazenadas na geladeira. A melhor condição para o armazenamento das raízes é em câmara fria e embaladas com saco plástico, onde as raízes mantiveram a qualidade apropriada para comercialização durante até 30 dias de armazenamento.

Aumento da capacidade produtiva por meio da padronização de embalagem

Currently the market share gains and complying fully with the demand in the market is considered essential for the companies survival against the competitors. This work aims to analyze the packing standardization as a strategy to increase production capacity. As result it was implemented a project to standardize the primary packaging of products offered, so it was possible to reduce inventory, increased productivity, improved workload of line operators and decrease the complexity of the planning of the primary packaging and production planning as well, all these factors contributing to cost reduction and increased competitiveness

Structure characterization of molecular complexes for non-linear optical materials. II. 1 : 1 complexes of 4-methyl-morpholine-N-oxide (1) and 3-picoline-N-oxide (2) with 2,4,6-trinitrophenol, studied by X-ray, AM1 and DFT calculations

(1) C6H2N3O7- center dot C5H12NO2+, Mr = 346.26, P2(1)/c, a = 7.2356(6), b = 10.5765(9), c = 19.593(2) angstrom, 3 beta=95.101(6)degrees, V = 1493.5(2) angstrom(3), Z = 4, R-1 = 0.0414; (2) C6H2N3O7- center dot C6H8NO+, Mr = 38.24, P2(1)/n, a = 7.8713(5), b = 6.1979(7), c = 28.697(3) angstrom, beta = 90.028(7)degrees, V = 1400.0(2) angstrom(3), Z = 4, R-1 = 0.0416. The packing units in both compounds consist of hydrogen bonded cation-anion pairs. The (hyper)polarizabilities have been calculated for the crystallographic and optimized molecules, by AM1 and at the DFT/B3LYP(6-31G**) level.
