在英国,铁和锌等必需矿物质摄入不足是一个公共健康问题,尤其是对女孩和年轻女性而言。在英国饮食中,大约30%和50%的锌和铁分别是由谷物提供的。在小麦中,大部分铁和锌都包含在糊粉细胞层中;然而,糊粉在小麦加工成白面粉的过程中被去除。而单质铁粉添加回白面粉在磨粉阶段,没有恢复锌。元素铁粉具有非常低的生物利用度,因此,在我们目前的生物技术和生物科学研究委员会饮食和健康研究产业俱乐部资助的项目中,我们正在研究糊粉作为一种生物可利用的矿物质来源的潜在用途,可以添加到小麦基食品中。这项工作与食品工业相关,并可能确立糊粉作为功能性食品成分用于强化一系列谷物食品的用途。
Inadequate intake of essential minerals such as iron and zinc is a public health concern in the UK, particularly for girls and young women. Approximately 30% and 50% of the zinc and iron, respectively, in the UK diet is provided by cereals. In wheat, most of the iron and zinc is contained within the aleurone cell layer; however, aleurone is removed during processing of wheat into white flour. While elemental iron powder is added back into white flour at the milling stage, there is no restoration of zinc. Elemental iron powder has very low bioavailability, and therefore, in our current Biotechnology and Biological Sciences Research Council Diet and Health Research Industry Club‐funded project, we are investigating the potential use of aleurone as a bioavailable source of minerals that could be added to wheat‐based foods. This work has relevance for the food industry and may establish the use of aleurone as a functional food ingredient for fortification of a range of cereal‐based food products.
