Furthermore, JM combined with air classification is available to separate starch from protein matrix (Graveland and Henderson, 1991) [ 20 ].

STARCH DAMAGE Megazyme

2019-1-2  The milling of wheat causes physical damage to a proportion of the starch granules of the flour. The level of starch damage directly affects water absorption and dough mixing properties of the flour and is thus of technological significance. Furthermore, damaged granules rapidly hydrate and are hydrolysed by α- and β-amylases, yielding fermentable sugars. In the latter stages of traditional long-fermentation procedures, when the natural sugars present in the flour have been fermented by yeast, maltose produced by amylolysis of damaged starch

2020-9-1  Flour samples milled by IM had a lower damaged starch content, higher trough viscosity, higher final viscosity and higher values of setback compared to samples processed by HM. After repeated milling of IM, the damaged starch content of the endosperm granules could be controlled below 1% (P < 0.05). There was a gap between H1 and H2 in the
