In the manufacture of products such as bread and cream-crackers mechanical development and long fermentation processes are used to develop dough. A rheological study of cream-cracker doughs made using both types of process has shown that fermentation weakens, but does not rearrange, intermolecular i

Abstract
The addition of aminoโacids to wheat flour doughs results in increased browning of the crust of the baked bread. Doughs to which glycine and lysine have been added show a decrease in gas production. An explanation for this decrease is offered by the assumption that the formation of Nโsubstituted glycosylamines from the added aminoโacids and the reducing sugars in the dough is responsible.

## Abstract Different quantities of additives (sodium chloride and oxalic acid) and antisolvent (ethanol) were used in order to define their influence on crystallization of glycine from aqueous solutions. The solubility curves were determined for all process conditions but the nucleation points onl
The clavicepamines are lysine-rich basic proteins isolated from saprophytic culture of ergot (Claviceps purpurea), having human pharmacological importance. Based on structure determinations, it was demonstrated that the 1-lysine (poly)peptides are the fundamental structural units of clavicepamines.
