Barley, corn, oats and wheat grains are products obtained by drying after heat treatment (steam) and crushing. In Flake (muesli), the main goal is to gelatinize the starch in order to increase the starch digestibility of the grains. Flake (muesli) grains are more delicious and pleasant to smell than unprocessed grains. Therefore, especially cattle and ovine cattle are consumed with love. Because it is heat treated in the process, it is free from harmful microorganisms. For this reason, it is a product that is consumed safer than unprocessed grain grains. According to the processed product, it is called Corn Flake, Barley Flake, Wheat Flake, Oat Flake. The implementation of this process in the form of classical annealing and crushing process is called grain crushing. Of these, the most consumed in the market is barley paste. Flake grains for ruminants are considered to have higher starch digestibility than grains obtained by other methods (broken, paste).
