The mechanism by which heat treatment improves the flour is
not fully understood, but it is known that during the heat treatment
process, protein denaturation and partial gelatinization of the
starch granules occurs, as well as an increase in batter viscosity
(Neill, Al-Muhtaseb & Magee, 2012). Sorghum flour contains starch
granules and non-starch components including non-starch polysaccharides,
lipids and proteins. By applying heat treatment to the
flour and removing the moisture, it is possible to modify its physical
and chemical properties. Limited research has been performed on
heat treatment of sorghum flour. Therefore, the objectives of the
present study were to investigate the effect of heat treatment on
the properties of sorghum flour and the potential use of heat
treated flour for gluten-free cake and bread production
