本研究以问卷调查的方式，了解消费者对食品添加剂的认知与安全认知。共有430名居住在韩国首尔的消费者参加了此次活动。结果显示，受访者非常关注食品中的防腐剂、着色剂和人工甜味剂。超过三分之二的人表示，有关食品添加剂的信息不足。他们将缺乏信息归因于难以理解食品添加剂的主题，以及教育和公共关系不足。近一半的受访者选择传单和小册子作为首选的信息传播媒介。本研究还通过配对的前后调查评估了信息传播(例如传单和小册子)对消费者防腐剂知识、行为和安全认知的影响。总体而言，知识得分从干预前的67.3%提高到干预后的91.9%。安全感得分显着提高，显示出测试前后60%的差异。与会者表示，传单和海报有助于了解防腐剂的类型和作用。试点前后调查的结果表明，消费者对食品添加剂的安全认知受到消费者意识和知识的影响。这项研究建议，必须开发让消费者熟悉各种类型的食品添加剂的沟通程序，以提高消费者的安全认知，并回应消费者对食品添加剂的信息需求。(C)2011爱思唯尔有限公司。保留所有权利。
In this study, consumer awareness and safety perceptions of food additives were identified via survey questionnaire. A total of 430 consumers living in Seoul, Korea participated. The results showed that the respondents were very concerned about preservatives, colorants, and artificial sweeteners in foods. More than two thirds expressed that information on food additives was insufficient. They attributed this lack of information to difficulties understanding the subject of food additives and insufficient education and public relations. Almost half of the respondents chose leaflets and pamphlets as preferable mediums of information transmission.This study also evaluated the impacts of information transmission (e.g., leaflet and pamphlet) on consumers' knowledge, behavior, and safety perceptions of preservatives using matched pre- and post-surveys. Overall, knowledge scores were improved from 67.3% to 91.9% before and after the campaign, respectively. Safety perception scores significantly increased showing a 60% difference between the pre- and post-tests. The participants indicated that leaflets and posters were useful to understand both the types and functions of preservatives. The results of the pilot pre- and post-surveys implied that safety perceptions of food additives were affected by consumer awareness and knowledge. This study suggests that communication programs familiarizing consumers with various types of food additives must be developed in order to increase safety perceptions and to respond to consumers' information needs on food additives.
