    1. Active Packaging System Based on Ag/TiO2 Nanocomposite Used for Extending the Shelf Life of Bread. Chemical and Microbiological Investigations (pages 271–284)

      The Ag/TiO2 based on packaging considerable extends the shelf life and microbiological safety of white bread. The Ag/TiO2 nanocomposite reduces the degradation rates of nutritional compounds and inhibits the microorganisms' proliferation, and thus, the shelf life and microbiological safety of bread are extended. The Ag/TiO2 nanocomposite shows oxygen and water scavenging property.

    2. The Impact of Plasma-modified Films with Sulfur Dioxide, Sodium Oxide on Food Pathogenic Microorganisms (pages 285–292)

      In this study, plasma modification was carried out in barrier discharge under atmospheric pressure. Sulfurdioxide and/or sodium oxide was used as the coating precursor. The results show that the films treated with a mixture of argon and sulfur dioxide inhibited microbial growth considerably better than those with coatings containing argon and sodium oxide. The highest levels of growth inhibition, of 86% for Staphylococcus aureus and 82% for Escherichia coli, were achieved with films carrying a sulfur-containing coating (1.4% SO2).

    3. Toward New Polymeric Oxygen Scavenging Systems: Formation of Poly(vinyl alcohol) Oxygen Scavenger Film (pages 293–302)

      A cobalt-threonine complex is used as oxygen scavenger after incorporation in a polar polymer film based on poly(vinyl alcohol). The complex needs to be activated by water before being efficient allowing an easiest industrial process. The oxygen absorption capacity of the complex after its incorporation in poly(vinyl alcohol) is 2.5 mg of oxygen per gramme.

    1. European Consumers' Perceptions of Time–Temperature Indicators in Food Packaging (pages 303–323)

      Kyösti Pennanen, Caralampo Focas, Vilja Kumpusalo-Sanna, Kaisu Keskitalo-Vuokko, Imke Matullat, Mariem Ellouze, Saara Pentikäinen, Maria Smolander, Virpi Korhonen and Margareetta Ollila

      Sixteen qualitative focus groups and a quantitative survey were conducted in four European countries (Finland, Greece, France and Germany) in 2012 to capture consumers' views on both time–temperature indicator (TTI) technology concept and two commercial TTI applications. The results of the study show that consumers in all countries understand the value of the TTI concept, but the studied applications did not meet the consumers' expectations implying the need for further work to enable the TTI acceptance among consumers.

    2. Capturing the User Mindset – Using the Online Research Community Method in Packaging Research (pages 325–340)

      Article first published online: 22 SEP 2014 | DOI: 10.1002/pts.2106

      This paper presents a case study of using an online research community as a method for collecting information, user experiences, and ideas from packaging users. 137 participants were recruited to a closed online platform. The various discussion topics and tasks were predetermined by the researchers, and new topics were introduced daily over a period of 13 days. The benefits, challenges, and opportunities of the method are discussed in relation to packaging research.

    3. Professionals' View of Consumers' Packaging Interactions – A Narrative Analysis (pages 341–355)

      The article investigates how professionals perceive consumer interactions with packaging. The aims are to provide insight into factors relevant for consumer-centred packaging development in industry and to identify the potential challenges for adopting a consumer-centred model. As a result, five narratives and five challenges for packaging development were constructed.

    1. Modelling of Migration from Printing Inks on Paper Packaging (pages 357–366)

      The migration model of contaminants from inks on paper packaging to food is developed based on the penetration of ink in paper and Fick's diffusion by considering the mass transfer coefficient and partition coefficient in the interface between paper and food. The fitting method is used between the model and the migration experimental data to obtain the diffusion coefficients DP and mass transfer coefficients hm for dibutyl phthalate (DBP) and acetyl tributyl citrate (ATBC). It is found that there exist linear relationships between ln(DP) and 1/T, and also between ln(hm) and 1/T for DBP and ATBC.

    2. Microperforation of Three Common Plastic Films by Laser and Their Enhanced Oxygen Transmission for Fresh Produce Packaging (pages 367–383)

      Laser microperforation of biaxially oriented polypropylene, biaxially oriented polyethylene terephthalate and low-density polyethylene (LDPE) films (neat LDPE and LDPE containing 0.5 wt% of silica-based additive) was investigated. Explanations on different perforation performances and characteristics among these films were contributed to polymer inherent property and its interaction with laser. Based on the measured oxygen transmission rate using the static method, laser perforation appeared to be an effective method for developing high-oxygen permeable plastic films.
