1. Análise de simulantes para produtos ácidos acondicionados em embalagens metálicas / Analysis of simulants to acidic products conditioned in meal package
Tin-plate cans represent most of the cans for canned food. Since they are not inert, during the storage period, interaction occurs with the product and metal dissolution can occur, especially when it is acid food. To minimize this interaction it is used organic coatings, and epoxy-phenolic resin is the the most used. As the foods are complex biochemical syst

2. Polipropileno clarificado recoberto com filme de carbono amorfo hidrogenado pelo processo PECVD / Clarified polypropylene coated with hydrogenated amorphous carbon film by PECVD process
This work aimed to study the feasibility of application of clarified polypropylene (cPP) coated with hydrogenated amorphous carbon films (a-C:H) deposited by Plasma Enhanced Chemical Vapour Deposition (PECVD) in food packaging, mainly targeting the segment of bottles for carbonated beverages. For the deposition of films of a-C:H using different deposition pa

3. Avaliação dos tipos de processamento na descontaminação e na degradação do polipropileno reciclado / Evaluation of types of processing in the decontamination and degradation of recycled polypropylene
Polypropylene is one of the most used polymers worldwide, especially by the disposable packaging industry, causing serious environmental problems. Despite the fact that recycling this polymer has become common in Brazil due to its growing market, there are still some restrictions regarding its use in direct-contact food packaging. Therefore, in order to eval

4. Simulação numérica da migração de elementos metálicos e do monômero -caprolactama de embalagens poliméricas irradiadas para simulantes de alimentos / SIMULATION STUDY OF -CAPROLACTAM MONOMER AND METALLIC ELEMENTS MIGRATION FROM IRRADIATED POLYMERIC PACKAGING INTO FOOD SIMULANTS
For decades migration study of chemical compounds from packaging into food, such as metals, residual monomers and additives, is a very important issue, concerning public health and minimize chemical contamination. In this work, it was done irradiations of packagings taken in contact with food simulant, and it was studied this migration through a mathematical

5. Migração de plastificantes e avaliação de propriedades mecânicas de filmes de poli(cloreto de vinila) para alimentos / Migration of plasticizers and evaluation on mechanical properties in poly(vinyl chloride) film into foods
The migration of packaging compounds can compromise the chemical and mechanical proprieties of the material, as well as causing toxicological problems with the consumer. The purpose of this work was to evaluate migration of plasticizers di-(2-ethylhexyl)phthalate (DEHP), di-(2-ethylhexyl)adipate (DEHA) and acetyl tributyl citrate (ATBC) used to produce poly(

6. Implicações nutricionais decorrentes do uso de panelas brasileiras de aço inoxidavel, ferro e pedra-sabão (esteatito). / Decurrent nutricionais implications of Brazilian the stainless steel pan use, iron and rock-soap (esteatito).
Soapstone, clays, glass, iron, aluminum, stainless steel, are among the different materials used to make cookware. It is known that during food preparation interactions between the food and cookwares do occur, some of them being positive, some null, while others could be harmful for our health. This study evaluated the nutritional implications that result fr

7. Bacillus Spore Inactivation Methods Affect Detection Assays
Detection of biological weapons is a primary concern in force protection, treaty verification, and safeguarding civilian populations against domestic terrorism. One great concern is the detection of Bacillus anthracis, the causative agent of anthrax. Assays for detection in the laboratory often employ inactivated preparations of spores or nonpathogenic simul
