Abstract
|
|
|
|
This study was performed to investigate flavor modification effects of β-cyclodextrin (β-CD) inclusion complex on the flavor of Doenfang (Korean traditional fermented soy paste) with various substitution levels of 10, 20, and 30%. Water and protein contents of the substituted samples showed significantly lower values compared to those of control(p<0.05). Results of DSC(Differential Scanning Calorimetry) showed that significantly higher ΔH values (386.03 and 304.23) in the 20 and 30% substituted samples represented the stabilized internal cell structures(p<0.05). Internal structures observed with the scanning electronic microscope tended to be less rough and organized making even and ordered internal cell structures as the substitution levels were increased. Results of sensory evaluation showed significantly higher savory flavor and significantly lower bitter and astringent flavors with the substituted samples compared to those of control(p<0.05). Results from this study showed the substitutions of β-CD could possibly modify unfavored flavors of Doenjang while keeping the unique, nutritional and functional properties when β-CD was used as a flavor modifier.
