BACKGROUND: The influence of monoacylglycerol Rimulsoft Super(V) and L-glutamic acid added to wheat flour dough was studied. Properties of the doughs were evaluated on the basis of chemical analysis and rheological measurements on a farinograph. Bakery products made from these doughs were subsequently subjected to sensory analyses. RESULTS: It was found that L-glutamic acid influenced the water absorption in dough more (50.0 g kg(-1); water absorption 56.6%) than monoacylglycerol Rimulsoft Super(V) (50.0 g kg(-1); water absorption 55.0%). Farinograph measurements showed that doughs with the addition of L-glutamic acid resembled flour containing high-quality gluten, but dough with the addition of monoacylglycerol Rimulsoft Super(V) corresponded to 'weak' flour.Sensory analyses revealed that, in comparison with the control sample of French loaf, the saliva-absorbing capacity increased in the French loaf with the highest addition of L-glutamic acid (30.0 g kg(-1)). Deterioration in quality and texture in French loaf with addition of L-glutamic acid (8.0 g kg(-1), 30.0 g kg(-1)) was noted. No other statistically significant differences were found. CONCLUSION: It is acceptable to add both additives to dough in order to modify its rheological properties.
