Cereal crop feedstocks

Grain crops, specifically cereal crops, are major feedstocks for the food and fermentation industry because of their high starch and protein content. Cereal crops are by far the most important crops cultivated globally. In 2009 about 2.5 billion tonnes of cereals were produced worldwide (FAO, 2010). Wheat, com, barley and sorghum are the common starch sources that have been traditionally used in food and industrial bioproduct manufacturing. Straw and stocks from cereal crops are also important as lignocellulosic feedstock for bioproduct manufacturing. 

Straw and Other Crop Residues Crop residues are another source of renewable feedstock that do not find their way into milling processes, especially the residues which are already separated from the crop during or directly after harvesting. For most cereals and oil crops, this Hgnocellulosic biomass is called straw, for example, wheat straw, rice straw, or barley straw. The crop residues of maize are known as corn stover. 

Renewable raw materials (RRM) as industrial feedstock for the manufacture of chemical substances and products, such as oils from oilseed crops, starch from cereals and potatoes, and cellulose from straw and wood, have recently received attention from policy makers. By...

Whole crop biorefineiies use various types of feedstock such as cereals, maize, rye, wheat, and triticale. Grain and straw are first separated from one another via suitable mechanical...
