Developing Food Consumer Attitudes towards Ionizing Radiation and Genetic Modification.

BACKGROUND/OBJECTIVES: This study investigates consumer perceptions and acceptance of ionizing radiation (IoR) as a perishable food stabilisation technology. Consumers' preferences influence the success of emerging food technologies. Therefore, a comprehensive understanding of consumers' behavioural responses and their development over time is essential.

METHODS

This research employs a mixed-methods approach, surveying 313 young adults in New Zealand on their views of both irradiated (IoR) and genetically modified (GM) highly perishable foods. This study explored both participants' attitudes towards these two technologies and also their willingness to consume these foods.

RESULTS

The qualitative research revealed a preponderance of "affective" associations over "cognitive" associations with regard to both IoR and GM technologies. The quantitative research indicated that where consumers were given time to reflect, evaluations of GM improved, while those of IoR did not ( < 0.01). There was a gender divide, with females being more positively inclined towards GM and males towards IoR ( < 0.01). Both technologies were significantly disfavoured compared to non-treated products ( < 0.01). There was a significant discrimination when the two technologies were presented as concepts and as products. GM was more favourably received as a concept than as a product ( < 0.01), while IoR was disfavoured in either form. The two food neophobia scales that were tested showed a divergence in performance, with the more affectively based scale showing a higher level of correlation with behaviour.

CONCLUSIONS

This research reveals that a largely affective (visceral) distrust of both IoR and GM exists within this young food consumer sample. As it is affective in nature, this position will be very resistant to education efforts, particularly if they are "cognitively" based. However, a significant softening of these affective attitudes towards GM products indicates that such efforts may be effective, given time and investment.
