科学看待食品添加剂

近几年接连出现的食品安全问题,让消费者对食品添加剂倍加关注。食品添加剂是为改善食品色、香、味等品质,或为防腐保鲜而加入食品中的人工合成或天然的物质。经国家批准生产、按照有关标准使用食品添加剂,应该是安全的。我们日常使用的味精、鸡精、食盐、食用碱、点豆腐的卤水等,都属于

Creating Value for Customers,Clients, Partners and Society: An Introduction to the Special Issue on Food Waste

ABSTRACT

Roughly one-third of edible food produced in the world is wasted, that is, it is never consumed by humans, despite the persistent demands for nutrition throughout the world. The American Marketing Association defines marketing as “…the activity, set of institutions, and processes for creating, communicating, delivering, and exchanging offerings that have value for customers, clients, partners, and society at large.” When it comes to food, an increasing number of these key stakeholders question how a global marketing system that routinely wastes a startling fraction of its product comports with “…value for customers, clients, partners, and society at large,” and whether the food marketing system can do more to sustainably convert scarce planetary resources into global nutrition. We introduce the articles in this special issue, which provide an intellectual and empirical basis for exploring how the global marketing system generates a substantial amount of food waste and how the food marketing system can do more to reduce the amount of wasted food.     

Australian Exports of Horticultural Crops with Special Reference to Fresh Citrus Fruits

Abstract

Exports of horticultural products, in particular fresh citrus fruits, are becoming increasingly important in terms of export earnings for Australia. However, Australian fresh citrus exports account for about 12 per cent of the total production of citrus. About 57 per cent of total exports is sold on Asian markets. The purpose of this study is to examine the problems and prospects for fresh citrus exports on world markets and, in particular, in the Asian region. The findings of the study reveal that higher freight and labour costs have made Australian citrus less competitive on world markets. Thus, producers have an incentive to sell over 80 percent of the total production of citrus on domestic markets. However, there is scope for greater market opportunities in the Asia-Pacific region for Australian fresh citrus fruits. Australia should increase the yield per tree, improve the quality of citrus fruits and identify the need for market promotion and research in order to increase the volume of citrus exports on world markets, especially in the Asia-Pacific region.

The impact of lifestyles and food knowledge on the food patterns of German children

The German youth is relatively well informed about healthy eating, but does not act in accordance with this knowledge. It is also known from empirical studies that there is an association between lifestyles, food knowledge and the eating patterns of older teenagers. However, is there a similar correlation in regard to younger children? This article shows results of a study addressing this issue by empirically investigating leisure time activities, food intake and food knowledge. The study conducted with 907 children, on average 12 years old, out of an urban region in northwest Germany using a written questionnaire, implies that food patterns and food knowledge have to be improved because they are – on average – only marginally acceptable. On this level, they are not in line with a healthy future. For the first time in Germany, food patterns and food knowledge of seventh grade pupils were analysed in relation to their lifestyles. The study revealed four lifestyles. One family‐oriented lifestyle and three non‐family oriented lifestyles: outdoor and sociable youth, culture‐oriented youth, and multimedia kids. The family‐oriented lifestyle influences the children's food patterns in a positive way; the three found non‐family‐oriented lifestyles lead to less preferable food patterns. The results imply that there is a phase of unhealthy food patterns at the beginning of the second life decade, which seems to be linked to the detachment from the parents and the gained independency, expressed by the first self‐chosen lifestyles. As lifestyles have such a vital influence on healthy eating, and family is no longer the place where children get their everyday competencies, school has to enable pupils to make healthier food and lifestyle choices.     

建立有机食品安全快速检测全程可追溯系统的探究

随着经济的不断发展,人民生活水平的不断提高,人们对食品的关注重点也从"吃饱"向"吃好"转变,对"舌尖上的安全"有了更高的要求。于是促进了有机农业、生态农业、自然农业、再生农业等一系列关乎自然环境、生态文明建设的新型农业领域的兴起。国家"十三五"对于食品安全提出了更高要求,要求建立食品安全全程可追溯体系,建立"一站式"食品安全监测平台,使食品安全检测海量信息实时传输、存储、分析、运用成为可能。对食品安全进行风险监测、评估和预警,也必将促进我国在保障食品安全问题上又上一个新台阶。
