This paper reviews the current literature on consumers’ buying intentions in relation to organic food purchases, and finds a critical research gap in relation to exploring the role of marketing communications. Consequently this paper develops a conceptual model. The paper examines the central role of marketing communications as moderated through the variables of personal values, trust and perception about organic food. The paper argues that further empirical research is required to explain the divergence between consumers’ generally positive attitudes towards organic food and their relatively low levels of purchases.
