Developing beta glucan barley sustainable

项目摘要

Spring barley plays an important role in sustainable rotations, requiring lower inputs of nitrogen fertilizer, herbicides, fungicides and plant growth regulators than winter wheat and facilitates either over-winter stubbles for wildlife or use of cover crops. In recent years there has been an increase in the spring barley area in England, mainly to help control black-grass, a predominately autumn-germinating weed. The UK produces over 7m tonnes of barley each year, predominantly for use in animal feed, brewing, distilling and export. The food industry uses little barley even though barley can deliver equivalent health benefits to oats. These are largely due to inherently high levels of beta-glucan: a non-starch, non-cellulosic polysaccharide which is found in the cell walls of cereal grains. This remains undigested in the human small intestine, acting as a soluble fibre which confers significant dietary health benefits, through actively lowering blood cholesterol and slowing post-prandial glucose release. New food markets for barley would increase economic and social sustainability by providing farmers with higher value markets for an established crop, and by improving population health by reducing risk of type-2 diabetes and cardio-vascular disease. Our project aims to support the development of healthier wholegrain barley as a food ingredient, by increasing our understanding of the genetic and environmental factors that can impact on beta-glucan levels.

春季大麦在可持续旋转中起着重要的作用，需要比冬小麦要较低的氮肥，除草剂，杀真菌剂和植物生长调节剂的投入，并促进过冬季的残茬用于野生动植物或使用覆盖作物。近年来，英格兰的春季大麦地区有所增加，主要是为了控制黑草，主要是秋天的杂草。英国每年生产超过7m吨的大麦，主要用于动物饲料，酿造，蒸馏和出口。即使大麦可以为燕麦带来同等的健康益处，食品行业也很少使用大麦。这些很大程度上是由于固有高水平的β-葡萄糖：一种非淀粉，非纤维化多糖，它在谷物谷物的细胞壁中发现。在人类的小肠中，这仍然无法消除，充当可溶性纤维，通过积极降低血液胆固醇并减缓后源性葡萄糖的释放来赋予饮食健康益处。大麦的新食品市场将通过为农民提供较高价值的农作物市场，并通过降低2型糖尿病和心血管疾病的风险来改善人口健康，从而提高经济和社会可持续性。我们的项目旨在通过增加对可能影响β-葡聚糖水平的遗传和环境因素的理解来支持更健康的全麦大麦作为食品成分。
