AbstractThe barrier solutions presently available on the market all have their
drawbacks, e.g. cost, water‐sensitivity, opacity or perceived environmental
bad‐will. At the same time there is a trend to use more plastic‐based packaging
materials for different applications, e.g. as replacements for metal and glass
containers. This situation has stimulated the industry to provide new, more
efficient ... hiện toàn bộ

AbstractThe health benefits of probiotic functional foods have been widely
reported. However, manufacturers face great challenge in guaranteeing delivering
beneficial numbers of viable probiotic bacteria through to the end of the
product shelf life. The oxygen toxicity of some probiotic species has been shown
to contribute to reduced viable counts. The packaging system favoured by
manufacturers ma... hiện toàn bộ
AbstractThe long‐term influence of electron beam irradiation on food packaging
materials (OPP) was studied. After irradiating the material at dose levels of 2,
5 and 10 kGy, we have shown a partial or complete disappearance of the
antioxidant (Irganox 1010 and Irgafos 168) over time and a release of five new
compounds resulting from antioxidant degradation. All of these degradation
compounds have ... hiện toàn bộ

AbstractTo measure the biodegradability of packaging materials, a scientific and
methodological approach is proposed, using the results obtained with cellulosic
materials as models. Their degradation was evaluated using a respirometric
method based on the measurement of CO2 released by microorganisms (Pseudomonas
fluorescens and a mixture of cellulolytic bacteria). Our study was conducted in
confi... hiện toàn bộ

AbstractProbiotic bacteria, added to yoghurt to impart health benefits, require
a low‐oxygen environment for maximum viability. The aim of this experiment was
to produce yoghurt with minimal oxygen content using packaging systems. Three
packaging systems were evaluated for the effect they exert on the dissolved
oxygen content of two types of yoghurt. High‐impact polystyrene (the Australian
yoghurt... hiện toàn bộ
