TGase had negative effect on the specific volume of breads at
both levels; however, guar gam had positive role in enhancing their
specific volume. Guar gum addition alone did not have any effect on the breads’ texture, but its simultaneous incorporation by TGase at level 1 u g1 pro had positive effect and at 10 u g1 pro had negative effect on their texture. Guar gum addition resulted in texture softening on the production date, but TGase addition and its dose elevation led to more crumb hardness of the bread samples at this time. Overall, we can conclude that high quality gluten-free breads could be prod uced by addition of 30 g kg1 of guar gum and1ug1 pro of TGase enzyme to the formulation.
