This study aims to evaluate conceptual considerations of the sociology of agriculture and food from inside and outside of the literature in relation to transnationalization and its claim on the emergence of a transnational state. Although the history of the literature can be traced back to mid-1970s, its development corresponds to 1990s which is also the period that witnessed the hegemony of the concept of globalization in social sciences. This study argues that the claim on transnationalization reflects the intimate relationship of sociology of agriculture and food with the globalist interpretation of the concept of globalization or globalization theory which suffers from methodological and theoretical problems mainly in relation to the analysis of immanent contradictions and distinctive features of capitalism. With the criticism of the concepts of globalization and transnationalization, this study aims to break the intimate relationship of the sociology of agriculture and food with the globalization theory and suggests that the concept of imperialism is a powerful analytical concept in comprehending the transformation of capitalist relations, particularly the agrifood relations since late 1970s. In other words, this study aims to reevaluate the concepts (agrifood system and food regime) and problematics formulated in the sociology of agriculture and food literature within the theoretical framework based on the concept of capitalist imperialism exemplified in the analysis of transformation of agrifood relations since 1980 in the case of Turkey.
