Melting thermogram differential thermal analysis (DTA) results showed that, up to about 25% moisture content, all the water in dough is of the bound type. Above this moisture content, approximately one-third of the additional water was bound and the remaining two-thirds was free (freezable) water. Doughs from flours (wheat cultivars) of different mixing strength contained approximately the same amount of bound water. Flour protein content, amount of damaged starch, dough-mixing time, and added chemicals (sodium chloride, N-ethylmaleimide, potassium iodate, ascorbic acid, and cysteine) did not affect the amount of bound water as determined by the malting mode DTA.
