The influence of packaging materials on the dissolved oxygen content of probiotic yoghurt
Packaging Technology and Science - Tập 15 Số 3 - Trang 133-138 - 2002
Craig W. Miller, Minh H. Nguyen, Michael L. Rooney, Kaila Kailasapathy
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
The control of dissolved oxygen content in probiotic yoghurts by alternative packaging materials
Packaging Technology and Science - Tập 16 Số 2 - Trang 61-67 - 2003
Craig W. Miller, Minh H. Nguyen, Michael L. Rooney, Kaila Kailasapathy
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
Recent innovations in barrier technologies for plastic packaging—a review
Packaging Technology and Science - Tập 16 Số 4 - Trang 149-158 - 2003
Jakob Lange, J.‐A. E. Månson
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
Biodegradability of packaging materials using a respirometric method
Packaging Technology and Science - Tập 7 Số 2 - Trang 87-98 - 1994
Véronique Coma, Yves Couturier, B. Pascat, G. Bureau, Stéphane Guilbert, J.L. Cuq
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
Effects of electron beam irradiation on commercial polypropylene: Kinetic study of antioxidant degradation
Packaging Technology and Science - Tập 5 Số 4 - Trang 197-204 - 1992
F. Bourgés, G. Bureau, B. Pascat
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
