A team of scientists is hoping to produce mineral-enriched nutritious flour using high-powered x-rays.
The scientists are from the Rothamsted Research, an institute of Biotechnology and Biological Sciences Research Council (BBSRC).
They are using high powered x-rays from the world famous Diamond Light Source, a third generation synchrotron in Oxfordshire, UK, to carry out fluorescence analysis in favour of traditional staining techniques to identify new wheat varieties with added health benefits.
This rapid approach not only locates several different minerals simultaneously, but also provides information about their chemistry and digestibility.
According to Dr Andrew Neal, who leads the project, "Essentially, we are looking for new healthier grain. Diet deficiency is a big global issue; nearly one million people a year die worldwide as a result of iron and zinc deficiency. Milling methods and our preference for white flour products over wholegrain means that much of the essential mineral content of wheat grains is lost during milling to produce white flour."
"We are looking for ways to increase iron and zinc quantities in white flour, ensuring they end up in our diet," he said.
A wheat grain consists of bran (the outer layer), the germ (or embryo) and white flour (or starchy endosperm).
