The importance of food naturalness for consumers: Results of a systematic review
TLDR
In this paper, a systematic review identified 72 studies conducted in 32 countries involving 85,348 consumers and found that the items used to measure the importance of naturalness can be classified into three categories: 1) the way the food has been grown (food origin), 2) how the food have been produced (what technology and ingredients have been used), and 3) the properties of the final product.Abstract:
Background Consumers’ perceptions of naturalness are important for the acceptance of foods and food technologies. Thus, several studies have examined the significance of naturalness among consumers. Nonetheless, the aspects that are considered essential in perceiving a food item as natural may vary across consumers and different stakeholder groups. Scope and approach This systematic review identified 72 studies conducted in 32 countries involving 85,348 consumers. We aimed to answer the following questions: 1) How has the perceived importance of naturalness for consumers been defined and measured? 2) To what extent is perceived naturalness important to consumers? 3) Are there individual differences regarding the importance given to food naturalness that can be explained by consumers' characteristics? 4) Do consumers’ attitudes toward food naturalness influence their intentions and behavior? Key findings and conclusions The review clearly shows that for the majority of consumers, food naturalness is crucial. This finding could be observed across countries and in the different years when the studies were conducted. Therefore, neglecting the aspect of naturalness in the food industry may be very costly in the end. Our review also reveals differences across studies in how naturalness has been defined and measured. Based on a content analysis of the measurement scales, the items used to measure the importance of naturalness can be classified into three categories: 1) the way the food has been grown (food origin), 2) how the food has been produced (what technology and ingredients have been used), and 3) the properties of the final product.read more

Conflicts between chicken welfare and public health risks in poultry husbandry : stakeholders’ perceptions and moral convictions
TL;DR: In this article, the authors studied stakeholders' views on the conflict between chicken welfare and public health and food safety risks and relevant moral arguments and convictions, and concluded that differences in views between and within stakeholder groups regarding perceptions, moral convictions and judgements and a dilemma in poultry husbandry could be explained by differences in perceptions of chicken welfare, and moral convictions related to chicken welfare; differences in weighing up of moral values; 4) context, i.e. whether or not someone is involved in poultry farming; 5) affect and intuitions; 6) knowledge and experiences related
