The past twenty years have seen the application of biotechnology to generate nutritionally improved food crops. Biofortified rice, cassava, maize, sorghum and other staple crops biofortified with essential micronutrients have great potential to benefit the world's poor, in terms of both health and economics. This paper describes the use of genetic modification to generate crops that are biofortified with zinc. Examples of zinc-enhanced crops which have been developed using biotechnological approaches will be discussed, and new approaches for research and development will be outlined. The impact of these biofortified crops on human health and well-being will be examined. This paper will conclude with a discussion of the obstacles that must be overcome to enable zinc-fortified crops to be accessible for the world's malnourished.
过去二十年见证了生物技术在营养改良食物作物中的应用。生物强化大米、木薯、玉米、高粱和其他主要作物强化了必需的微量营养素，在健康和经济方面都有很大的潜力造福世界贫困人口。本文描述了利用遗传修饰来生成富含锌的作物。将讨论使用生物技术方法开发的富含锌的作物的例子，并概述新的研究和开发方法。还将研究这些生物强化作物对人类健康和福祉的影响。本文最后将讨论克服使富锌作物能够为世界上营养不良的人所获得的障碍。
