3.9. Characterization of control and optimized PHGG bread
Bread supplemented with partially hydrolyzed guar gum at 1.59% concentration increased the values of specific volume, total dietary fiber (TDF), insoluble dietary fiber (IDF) and soluble dietary fiber (SDF) content of bread (Table 4). Firmness of bread fortified
with PHGG decreased from 321.5 to 302.7 which may be due to more water absorption of bread dough upon PHGG supplementation. Specific volume of PHGG bread showed a higher value as compared to control bread. No significant difference in overall acceptability of control and optimized PHGG bread was observed.PHGG supplementation at 1.59% concentration showed a significant increase in TDF and SDF whereas no significant difference was observed in IDF content of control and optimized PHGG bread.
