Local and organic food on wheels: exploring the use of local and organic food in the food truck industry

An exploratory study approach was used in this research to examine the use of local and organic food in Toronto’s food truck industry, the rationale for its use, and the challenges that food truck owners face in sourcing it. Results showed that all-but-one of the food trucks sourced local or organic food for their menu and were motivated by fresh taste/quality, social responsibility and customer preference. While there were challenges with utilizing organic/local food due to seasonality and cost, food trucks found they can derive benefits by way of increased patronage, menu differentiation, and competitiveness.

Food or ‘virtual’ food? The construction of children's food in a global economy

This paper explores the pattern of change and development in the marketization and reconstitution of food products for children. It is in the past few decades that global corporations’ search for new markets has come to focus intensely on children. In the eyes of global corporations, children are a huge, multibillion dollar market. Childhood may be understood as a social construction but its form is historically specific. At present, the market is defining and reconstituting cultural meanings of childhood without being contested by other significant groups in society. The paper goes on to explore how transnational corporations have transformed the production and marketing of food. The paper discusses the food risks and the challenges faced by the fast food industry which specifically targets children. The reconstitution and the rebranding of popular children's food is producing ‘virtual’ food rather than real food. We live in an era where childhood offers untold opportunities in the northern hemisphere. However, the global market has come to dominate and define the social construction of childhood. Other cultural forms of identity outside of consumerism are not making the same impression. The food risks associated with the global processing of food and the health risks that have been linked to these new food forms ultimately has consequences not only for children but for society as a whole.     

The role of newly emergent wholesalers in the food and drink industry in Japan,c.1880 to 1940: Focusing on the case of Kokubu

Abstract

This article explores the historical development of Japanese wholesalers in the food and drink industry in modern Japan. Despite many criticisms of Japanese wholesalers as being “multi-layered,” “old-fashioned,” and “outmoded,” there were historical reasons for the existence of wholesalers. While the traditional wholesalers remained even after the Meiji Restoration, the new wholesalers emerged by dealing with new products that appeared for the first time in modern Japan. Utilizing the historical conditions of both producers and retailers, the newcomers such as Kokubu boosted their development by innovative activities and gradually superseded the traditional wholesale market, firmly establishing their position as general wholesalers before the Second World War.
