view it has been shown that if <strong>the</strong> <str<strong>on</strong>g>vital</str<strong>on</strong>g> <str<strong>on</strong>g>gluten</str<strong>on</strong>g> doses are not in <strong>the</strong> right variati<strong>on</strong><br />

domain, taking into account <strong>the</strong> flour quality, <strong>the</strong> exogenous additi<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> proteic<br />

substance can lead to a worsening in dough’s rheological behavior (as a result <str<strong>on</strong>g>of</str<strong>on</strong>g><br />

excessive increase in tenacity or P/L ratio).<br />

From <strong>the</strong> point <str<strong>on</strong>g>of</str<strong>on</strong>g> view <str<strong>on</strong>g>of</str<strong>on</strong>g> <strong>the</strong> finishes product – <strong>the</strong> <strong>bread</strong>, <strong>the</strong> additi<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g><br />

<str<strong>on</strong>g>vital</str<strong>on</strong>g> <str<strong>on</strong>g>gluten</str<strong>on</strong>g> promotes a significative improvement in <strong>the</strong> physical properties <str<strong>on</strong>g>of</str<strong>on</strong>g> <strong>the</strong><br />

products, <strong>the</strong> maximum increase in volume being 73.2%.<br />

All <strong>the</strong> results regarding <strong>the</strong> rheological aspect <strong>and</strong> <strong>the</strong> quality <str<strong>on</strong>g>of</str<strong>on</strong>g> <strong>the</strong> finished<br />

product have shown that for low quality flours <strong>the</strong> optimal dosage for <strong>the</strong> <str<strong>on</strong>g>vital</str<strong>on</strong>g><br />

<str<strong>on</strong>g>gluten</str<strong>on</strong>g> is 3%, while higher doses lead to a worsening <str<strong>on</strong>g>of</str<strong>on</strong>g> <strong>the</strong> rheological properties<br />

<str<strong>on</strong>g>of</str<strong>on</strong>g> <strong>the</strong> dough <strong>and</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> <strong>the</strong> <strong>bread</strong> quality.<br />
