Titre : Experimental and numerical modelling comparison of thermal performance of expanded polystyrene and corrugated plastic packaging for fresh fish Titre original : Comparaison expérimentale et numérique de la modélisation de la performance thermique du polystyrène expansé et de la matière plastique ondulée utilisés comme emballage du poisson frais Type de document : texte imprimé Auteurs : Björn Margeirsson, Auteur ; Radovan Gospavic, Auteur ; Halldór Pálsson, Auteur Année de publication : 2011 Article en page(s) : pp. 573-585 Note générale : Génie Mécanique Langues : Anglais (eng) Mots-clés : Chilled food Temperature variation Insulation Packaging Heat transfer model Index. décimale : 621.5 Energie pneumatique. Machinerie et outils. Réfrigération Résumé : Experiments were carried out to compare the thermal performance of wholesale fresh fish boxes made of corrugated plastic (CP) and expanded polystyrene (EPS). Free standing boxes containing whole, fresh fillets were exposed to dynamic thermal loads. The chilling effect of frozen ice packs was studied by including them in some of the boxes. The frozen ice packs proved efficient for protecting fresh fish fillets against temperature abuse. Furthermore, the results show that the insulating performance of EPS is significantly better than the insulating capacity of CP. Maximum fish temperature of 16.1 °C (CP) and 11.0 °C (EPS) were recorded inside the thermally abused boxes without ice packs, initially at 1.9 to 2.1 °C and stored for 6.1 h at a mean ambient temperature of 19.4 °C. The fish temperature distributions during thermal abuse were studied with a numerical model for both packaging types, applying effective thermal properties of the sandwich-structured CP box. The purpose of the model was to cost effectively improve the packaging design. A satisfactory agreement between numerical results and experimental results was obtained.

Titre : Temperature fluctuations and quality deterioration of chilled cod (Gadus morhua) fillets packaged in different boxes stored on pallets under dynamic temperature conditions Titre original : Fluctuations de température et altération de la qualité des filets de morue (Gadus Morhua) conditionnés dans différents types de caisse et entreposés sur des palettes sous différentes conditions de température dynamiques Type de document : texte imprimé Auteurs : Björn Margeirsson, Auteur ; Hélène L. Lauzon, Auteur ; Halldór Pálsson, Auteur Année de publication : 2012 Article en page(s) : pp. 187–201 Note générale : Génie mécanique Langues : Anglais (eng) Mots-clés : Fish Temperature variation Packaging Pallet Insulation Storage life Résumé : A study was carried out to evaluate temperature variation and quality deterioration of packaged cod fillets as influenced by the box type used and their position on pallets under dynamic temperature storage. Storage life of thermally abused fillets was compared to that of fillets stored at steady temperature. Thermal performance of fish boxes, made of corrugated plastic on one hand and expanded polystyrene on the other hand, was also compared. Fillet temperature at multiple positions on the pallets along with environmental temperature and humidity were monitored during storage. Differences in product temperature of up to 10.5 °C were recorded on the thermally abused pallets stored for 6.4 h at mean ambient temperature of 18.5 °C. A reduction in storage life of 1.5–3 days was observed depending on the box position on the abused pallets compared to steady temperature storage.
