From the article ....."Fructose is a sugar that naturally occurs in fruits, while sucrose is usually extracted from sugar cane or sugar beets".
The packets sometimes have ( I think it is Silver Spoon as Tate and Lyle usually says cane sugar) a description of where it comes from and how it is made from Beet ,saying how good it is on Carbon Footprint /Food Miles etc etc because it is "Local Uk " rather than from abroad .
