1. Post-harvest conservation of Passiflora alata fruits under ambient and refrigerated condition
Abstract Brazil is the world's largest producer of passion fruit, a perishable fruit with reduced post-harvest shelf life, which limits its commercialization. For sweet passion fruit, Passiflora alata, there is little information about its postharvest conservation and shelf life under different storage conditions. Thus, the objective of the present study wa

2. Whey protein-based films incorporated with oregano essential oil
Abstract This study aimed to prepare whey protein-based films incorporated with oregano essential oil at different concentrations, and evaluate their properties and antimicrobial activity. Films were more flexible with increasing the concentration of oregano oil and water vapor permeability was higher in the films with oregano oil. Increasing the concentrati

3. Recycling assessment of multilayer flexible packaging films using design of experiments
AbstractThe viability of recycling post-industrial packaging waste, compounded from multilayer laminated PET-PE films, for production of polymer blends with good physico-mechanical performance is analyzed. Initially, several PET-PE model-blends were prepared from fresh polymers and were compounded with different formulations, based on design of experiments (

4. Optically transparent membrane based on bacterial cellulose/polycaprolactone
Optically transparent membranes from bacterial cellulose (BC)/polycaprolactone (PCL) have been prepared by impregnation of PCL acetone solution into dried BC membranes. UV-Vis measurements showed an increase on transparency in BC/PCL membrane when compared with pristine BC. The good transparency of the BC/PCL can be related to the presence of BC nanofibers a

5. Avaliação dos efeitos da radiação por feixe de elétrons na resistência de embalagens a Lasioderma serricorne, Plodia interpunctella e Sitophilus zeamais / Radiation effects evaluation for electrons sheaf in packages resistance in a Lasioderma serricorne, Plodia interpunctella and Sitophilus zeamais
As pragas de produtos armazenados constituem um problema para o homem, depreciando produtos e causando prejuízos econômicos. Dentre estas pragas temos o Lasioderma serricorne (F. 1792), Sitophilus zeamais (M. 1855) e Plodia interpunctella (H. 1813) conhecidos por infestar produtos armazenados como: grãos, farelos, farinhas, café, fumo, frutas secas e esp

6. Embalagens ativas de fonte renovável / Active packaging from renewable source
Active biodegradable packaging foams type were developed, obtained from cassava starch, to increase the shelf-life of minimally processed fruits. For this, active agents that prevent the proliferation of fungi, weight loss and, still, provide a visual indication (change of packaging color) of the packaged product quality, were added to the renewable packagin

7. OBSOLESCENCE AND PLEASURE: ELEMENTS FOR A CONTEMPORARY THEORY OF ALIENATION / OBSOLESCÊNCIA E PRAZER: ELEMENTOS PARA UMA TEORIA CONTEMPORÂNEA DA ALIENAÇÃO
This work aims to study contemporary alienation on the basis of two of its elements: obsolescence and pleasure. The first originates from the conditions to which are submitted not only the produced commodities, but also the worker, in face of the abolishment of worker¿s rights legislation operated by flexible accumulation. It is possible to suggest that the

8. Characterization of biofilms produced from pea (Pisum sativum) starch associated with xanthan gum and glycerol / Caracterização de biofilmes obtidos a partir de amido de ervilha (Pisum sativum) associado à goma xantana e glicerol
In the past few years, the attempt to obtain degradable flexible packaging has increased considerably. In this sense, starches obtained from different botanical sources have been evaluated to produce films. Most of these films present good mechanical characteristics and provide a good barrier to oxygen. Nevertheless, some limitations have been observed in re

9. Efeito de embalagens flexíveis na qualidade de leite pasteurizado e na sua aceitabilidade / Effect of flexible packaging on the quality of pasteurized milk and its acceptability
Este trabalho teve como objetivos avaliar quatro embalagens flexíveis para aplicação em leite pasteurizado e verificar sua influência na vida de prateleira desse produto. Primeiramente, avaliaram-se os filmes quanto à permeabilidade ao oxigênio, transmissão de luz, elasticidade e tração. Verificou-se, ainda, o número de camadas de cada embalagem, a

10. Empirical models for end-use properties prediction of LDPE: application in the flexible plastic packaging industry
The objective of this work is to develop empirical models to predict end use properties of low density polyethylene (LDPE) resins as functions of two intrinsic properties easily measured in the polymers industry. The most important properties for application in the flexible plastic packaging industry were evaluated experimentally for seven commercial polymer
