As the sugar beet harvest continues through the winter, a new way of processing it is being trialled which could allow more farmers to grow it. Sugar extraction is currently only done by one company - British Sugar - and is concentrated in the east of England. Most growers are within 60 miles of a processing plant. These huge factories heat the beet and get 95% of the sugar out. But we visit York University, where scientists are looking at a different way of extracting the sugar syrup which can be done on a much smaller, local scale, anywhere in the country.
