Wheat starch production

Wheat Starch Production, Properties, Modification and Uses... 

Estimated annual world wheat starch production was 2.11 million tons in 1993 and increased to 2.36 million tons in 1996.28 Because of significant expansion in manufacturing capacity in several countries, wheat starch production rose to 4.67 million tons in 2007 (Table 10.2).42 However, this production figure for wheat starch represents only a small fraction of the total world starch production of 60 million tons 41 By raw materials, wheat represents only 8% of world starch production, while potato, cassava and other crops contribute 4%, 14% and 1%, respectively com dominates at 73%. Approximately 52% of world starch is produced in the USA, 17% in the EU and 31% in other places 43 Wheat starch (<0.5% protein) is commercially produced in about 59 manufacturing plants in some 30 countries. The top 10 producers are France, the United States, Germany, The Netherlands, Australia, the United Kingdom, Belgium, Canada, Japan and China.

While the major aim in industrial wheat starch production is to produce a refined grade of A-starch, the production of a purified B-starch may also have commercial significance because of its unique uses, as described later in this chapter. In Europe, a new process was developed to separate B-starch into two fractions a high-purity, small granular starch and a feed fraction.53 The process involves enzyme treatment followed by high-pressure treatment and purification on fine screens, separators and decanters. Large and small wheat starch granules are marketed in Japan.85... 

The latest technological developments in wheat starch production are the high-pressure disintegration (HD)53,94-97 and the Tricanter 97 processes. The HD process, which is based on a highly sheared batter and on centrifugal forces for separation, was jointly developed by the Technical University of Berlin and Westfalia Separator.
