Abstract
The chemical composition of 92 Spring barley samples (81 of 2-row and 11 of 6-row type) grown in Sweden was investigated. Sugars, consisting of glucose, fructose, sucrose and fructosans, and starch were analysed by enzymic methods. Crude protein, crude fat, ash and crude fibre were determined with standard methods and total fibre was calculated by difference. Only small differences in chemical composition were observed between 2- and 6-row barleys. The dry matter of barley grains contained about 60% starch, 20% total fibre, 11 % crude protein, 3% crude fat, 3% crude fibre, 2% ash, 2% sucrose and small amounts of glucose, fructose and fructosans. The range of variation for starch was 14% -units, for total fibre 11 % -units and for crude protein 5%-units. When the content of starch increased, the content of all constituents analysed, except sucrose and fructosans, decreased.
