The continuous growth of world population and its concentration in the urban areas require food supplies that are continuous, sufficient and of good quality. To resolve this problem techniques have been developed for increasing food quantity and quality. The techniques are applied throughout the food chain from production, conservation and during distribution to the consumers (from "the field to the fork"). During handling of food, chemicals are often deliberately added to achieve improved processing and better quality. This is one of the main reasons food undergoes different kinds of contamination. This overview focuses on the application of supercritical fluids as media for handling food materials during processing with the perspective of reducing chemical contamination of food. Examples of developmental applications of this technique and on research work in process are presented. Emphasis is given to extraction and biotransformation techniques.
世界人口的持续增长及其在城市地区的集中,需要持续、充足且优质的食物供应。为解决这一问题,已开发出提高食物数量和质量的技术。这些技术应用于从生产、保存到向消费者配送(从“农田到餐桌”)的整个食物链。在食品处理过程中,常常故意添加化学物质以实现更好的加工和更高的质量。这是食品遭受各种污染的主要原因之一。本综述着眼于减少食品化学污染,重点关注超临界流体作为食品加工过程中处理食品原料的介质的应用。文中介绍了该技术的开发应用实例以及正在进行的研究工作。重点是萃取和生物转化技术。
