During the last two decades, the public and private sectors have made substantial research progress internationally toward improving the nutritional value of a wide range of food and feed crops. Nevertheless, significant numbers of people still suffer from the effects of undernutrition. As newly developed crops with nutritionally improved traits come closer to being available to producers and consumers, scientifically sound and efficient processes are needed to assess the safety and nutritional quality of these crops. In 2004, a Task Force of international scientific experts, convened by the International Food Biotechnology Committee (IFBiC) of ILSI, published recommendations for the safety and nutritional assessment of foods and feeds nutritionally improved through modern biotechnology (J. Food Science, 2004, 69:CRH62-CRH68). The comparative safety assessment process is a basic principle in this publication and is the starting point, not the conclusion, of the analysis. Significant differences in composition are expected to be observed in the case of nutritionally enhanced crops and must be assessed on a case-by-case basis. The Golden Rice 2 case study will be presented as an example of a food crop nutritionally enhanced through the application of modern biotechnology (i.e., recombinant DNA techniques) to illustrate how the 2004 recommendations provide a robust paradigm for the safety assessment of "real world" examples of improved nutrition crops.
在过去二十年中,公共部门和私营部门在国际上已在提高各类粮食和饲料作物营养价值方面取得了重大研究进展。然而,仍有大量人口遭受营养不良的影响。随着具有营养改良特性的新开发作物越来越接近可供生产者和消费者使用,需要科学合理且高效的流程来评估这些作物的安全性和营养质量。2004年,国际生命科学学会(ILSI)的国际食品生物技术委员会(IFBiC)召集的一个国际科学专家特别工作组发表了关于对通过现代生物技术实现营养改良的食品和饲料进行安全性和营养评估的建议(《食品科学杂志》,2004年,69卷:CRH62 - CRH68)。比较安全性评估过程是本出版物中的一项基本原则,是分析的起点而非结论。预计在营养强化作物的情况下会观察到成分上的显著差异,必须逐案进行评估。黄金大米2号案例研究将作为通过应用现代生物技术(即重组DNA技术)实现营养强化的粮食作物的一个例子进行介绍,以说明2004年的建议如何为改良营养作物的“实际”例子的安全性评估提供一个有力的范例。
