Consumer opinions and practices related to food additives in the purchase situation

The aim of this study was to describe consumer opinions and behaviour in the purchase situation. Sixty female customers, who had bought one of the food items chosen as focus foods (milk snacks, bread, beverages, condiments) of the study, were interviewed in six supermarkets in the metropolitan area of Helsinki. The subjects most often quoted good taste and familiarity as grounds for the selection of focus foods, but not the additive content. The majority of subjects considered Finnish foods to be mainly good and safe although 17 expressed some concern about food additives. The general concern of the subjects about additives did not conform with their actual buying behaviour.     

可持续粮食系统背景下粮食损失与浪费

全球粮食损失与浪费问题已广受关注。根据粮农组织统计,全球范围内供人类食用的粮食产量中,近三分之一(每年约13亿t)遭受损失浪费。受多重因素影响,我国目前在粮食产后储存、运输、加工、消费等环节也一直存在较为严重的损失浪费,粮食资源利用效率不高。因此减少粮食损失与浪费是当前加强粮食安全、减少粮食系统对环境影响过程中面临的紧迫任务。     

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.

Children's perception of food and healthy eating: dynamics behind their food preferences

Childhood obesity epidemic has been a popular topic for research as it has become a major health concern in many countries. As the focus of earlier studies has been predominantly on food marketing to children, there is still limited research on what other factors, apart from food marketing, influence their food preferences and eating habits. Bringing in children's perspectives as well as those of parents and guardians, this study aims to fill this gap by shedding light on further dynamics that can be influential on children's preferences. Through a qualitative inquiry, focus groups and individual interviews were conducted with children between the ages of 7 and 11. Aiming to investigate both meanings and practices, these sessions also included interactive and participatory research methods such as drawing, word games and role playing. Moreover, in-depth interviews were carried out with teachers and mothers to gain an understanding of their perspective on the topic. The findings show the different appeals and social influences behind children's food preferences, among which sensory and fun appeals as well as the influence of parents come forward. By revealing these different appeals of food and social influences, the study brings a new perspective to the discussions on childhood obesity and food marketing.
