Preferred information strategies for food allergic consumers. A study in Germany, Greece, and The Netherlands

Optimising the delivery of food allergy information. An assessment of food allergic consumer preferences for different information delivery formats

“…2 In Voordouw et al (2011), the average preference difference between the ideal types of booklet, label and ICT were at least 0.3 on the 7-point scale. A preliminary power analysis indicated that the sample size should be about 60 in order to find significant differences.…”

“…The third scenario consisted of a handheld electronic ''scanner''-in this case a small information terminal with bar-code scanner-which could be used to identify potential allergens through scanning the ingredient traceability information provided by the bar code. The different information delivery scenarios were assessed by (self-reported) food allergic consumers, including those from the Netherlands, and Germany, using an web-based online survey to identify preferences for the different characteristics within each type of information delivery tool (Voordouw et al, 2011). The use of conjoint analysis enabled identification of the most preferred approach to information provision within each generic information delivery scenario.…”

“…However, the conjoint analysis survey did not allow consumers to assess the actual use of ''prototypes'' of each of the three most preferred information delivery tools (Cornelisse-Vermaat, Voordouw, Yiakoumaki, Theodoridis, & Frewer, 2008b;Voordouw et al, 2011).…”

“…''Ideal'' profiles of information included for each tool have already been identified in previous research, although presented as a series of scenarios rather that as actual prototype information devices (Voordouw et al, 2011). The aim of the research presented here was to compare the preferences of food allergic consumers for the different ''ideal'' information strategies, once the results of the previous research had been translated into prototypes which could actually be tried and tested against actual ''products''.…”

A food recall case study in Australia – Towards the development of food safety applications for consumers

“…A review of recent research literature into the use of information technology to improve consumer food safety identifies evidence that labels, information sheets, barcodes, 2D barcodes and RFID tags have been researched in relation to nutritional information but a number of gaps remain including detail on preferences of consumers in the use of QR codes and/or NFC tags with mobile devices (Chrysochou, Chryssochoidis, & Kehagia, 2009). There is however some evidence (Voordouw et al, 2011) suggesting that some consumers' preference for the use of labels and information sheets is linked to their educational and technological backgrounds, although it is unclear whether these insights are culturally constrained or can be applied to Australian consumers. Based on the results of the study conducted by Reid, Li, Bruwer, and Grunert (2001), it appears that application of food related lifestyle consumer categorization is also an important dimension.…”
