2. 1. Antioxidant-Impregnated Polymers / Antioxidant Ability and Interactions with Food

   Author : Carolina Wessling; Avdelningen för livsmedel och läkemedel; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Food and drink technology; shelf-life; interactions; packaging; polymers; BHT; antioxidants; a-tocopherol; Livsmedelsteknik;

   Abstract : Interactions between antioxidant-impregnated low-density polyethylene (LDPE) and polypropylene (PP), and oxygen-sensitive foods have been investigated. BHT and a-tocopherol are two antioxidants commonly used in both foods and polymers. In general, BHT was rapidly lost from LDPE film in contact with various foodstuffs. READ MORE

4. 2. Dynamically predicted shelf-life service : Exploring and evaluating a potential sustainable food supply chain innovation

   Author : Malin Göransson; Förpackningslogistik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Supply chain; Packaging logistics; Food quality; Food waste; Sustainable innovation; supply chain; Packaging logistics; Food quality; Food waste; Sustainable innovation;

   Abstract : Roughly one third of all the food produced worldwide goes to waste. The global goals for sustainable development set by the United Nations in 2015 call for a 50% reduction of food waste per capita by 2030. We thus face several major food waste challenges that need academic and practical attention. READ MORE

5. 3. Dispersion Coating for Active Food Packaging: Aroma Interactions and Oxygen Scavenging

   Author : Anna Nestorson; Lars Järnström; Anders Leufvén; Caisa Andersson; José M. Lagaron; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active food packaging; Dispersion coating; Latex; Aroma compounds; Oxygen scavenging; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

   Abstract : ABSTRACTActive packaging materials prolong the shelf life or preserve the quality of packed food by absorbing oxygen, ethylene, moisture or odours, or by releasing antimicrobial agents, antioxidants or flavours. In dispersion coating, a latex is applied onto paper or paperboard to form a barrier film against water, water vapour, oil or gases. READ MORE

6. 4. Packaging methods and storage time : effects on beef quality

   Author : Åsa Lagerstedt Norström; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : Consumers base their purchasing choices on perceived quality and a bright red colour of beef is to many a sign of freshness and good meat quality, making colour the most important quality attribute for retailers. The most common consumer packaging types for beef in Sweden is high-oxygen modified atmosphere packaging (MAP), with the gas composition (80% O₂; 20% CO₂). READ MORE

7. 5. Quality Aspects of Modified Atmosphere Packaged Broccoli

   Author : Annelie Jacobsson; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; heat transfer; mass transport; quality; flavour; aroma; modified atmosphere packaging; broccoli;

   Abstract : The modified atmosphere packaging (MAP) of vegetables is used with the aim of prolonging the shelf-life of the packaged produce. The packaging material consists of a permeable film and as a result of the respiration of the produce and gas diffusion through the film, the O2 decreases and the CO2 increases inside the package.
