Organic food labels as a signal of sensory quality—insights from a cross-cultural consumer survey

Organic food labels are promising tools to transmit the positive image of organic products to consumers. Besides health-related aspects and environmental concerns, declaration of organic quality may have a positive impact on consumers’ taste perception. Many studies have proven the positive image of organic products, but very few have considered the link between labeling a product as organic and the consumer’s evaluation of sensory quality. This paper therefore investigates how organic consumers from six European countries (Germany, France, Italy, Poland, Switzerland, and the Netherlands) are influenced by the information that strawberry yogurt is produced organically or conventionally. Within the framework of a European Union-funded research project, a cross-cultural survey with a total of N = 1,797 respondents was conducted between October 2010 and February 2011. Standardized computer-assisted interview techniques were combined with sensory tests. Results show that the presence of an organic label may lead to an enhancement of taste perception. With the exception of Italy, consumers evaluated the same product sample slightly better when an organic label was shown. For the evaluation of conventional products, the opposite effect was found for three out of six countries. These findings reveal that the positive sensory image of the organic food branch transfers to single organic products, resulting in a better taste evaluation. However, the relatively weak label effect observed in all study countries suggests that an improvement of the sensory image of organic products is advisable. This can be addressed by enhancing the sensory performance of food products as well as by implementing extensive sensory marketing activities.

Background/Aims Persistent incidents of food fraud in China have resulted in low levels of consumer trust in the authenticity and safety of food that is domestically produced. We examined the relationship between the concerns of Chinese consumers regarding food fraud, and the role that demonstrating authenticity may play in relieving those concerns. Methods A two-stage mixed method design research design was adopted. First, qualitative research (focus groups n = 7) was conducted in three Chinese cities, Beijing, Guangzhou and Chengdu to explore concerns held by Chinese consumers in relation to food fraud. A subsequent quantitative survey (n = 850) tested hypotheses derived from the qualitative research and theoretical literature regarding the relationship between attitudinal measures (including risk perceptions, social trust, and perceptions of benefit associated with demonstrating authenticity), and behavioral intention to purchase “authentic” European products using structural equation modelling. Results Chinese consumers perceive food fraud to be a hazard that represents a food safety risk. Food hazard concern was identified to be geographically influenced. Consumers in Chengdu (tier 2 city) possessed higher levels of hazard concern compared to consumers in Beijing and Guangzhou (tier 1). Structural trust (i.e. trust in actors and the governance of the food supply chain) was not a significant predictor of attitude and intention to purchase authenticated food products. Consumers were shown to have developed ‘risk-relieving’ strategies to compensate for the lack of trust in Chinese food and the dissonance experienced as a consequence of food fraud. Indexical and iconic authenticity cues provided by food manufacturers and regulators were important elements of product evaluations, although geographical differences in their perceived importance were observed. Conclusions Targeted communication of authenticity assurance measures, including; regulations; enforcement; product testing; and actions taken by industry may improve Chinese consumer trust in the domestic food supply chain and reduce consumer concerns regarding the food safety risks associated with food fraud. To support product differentiation and retain prestige, European food manufactures operating within the Chinese market should recognise regional disparities in consumer risk perceptions regarding food fraud and the importance of personal risk mitigation strategies adopted by Chinese consumers to support the identification of authentic products.
