| Research Abstract |
We examined the flavor-enhancing effects of aroma fractions of some vegetables, celery and celeriac in soup-preparation using techniques of chemical analyses and sensory evaluation. The evaluations focused on the favorable complex flavor expressed as "koku" of chicken broth. We ascertained the importance of the odor substances of cooked celery and celeriac for the flavor-enhancing effects on chicken broth, and identified how the odor substances stimulate our sensation and produce the changes in the flavor of chicken broth. The effect of the volatile part of celery and celeriac were shown to be more significant than those of other vegetables. Potent odorants of celery and celeriac were determined by GC-MS-Olfactometry and three kinds of phthalides such as 3-buthylphthalide, sedanenolide, sedanolide were identified as the common potent odorants and 2-methoxy-4-vinylphenol was found as the characteristic odorant of boiled celeriac. Sedanenolide and phthalides mixture which component was the same as celeriac exhibited almost the same effects as celeriac volatiles. To elucidate the contribution mechanism of the phthalides to enhancing the flavor, the head gas of the phthalides were supplied retronasally into the oral cavity for tasting together with a separately supplied chicken broth. The flavor of chicken broth was enhanced by the head gas of the phthalides. These results showed that the volatiles of celery and celeriac enhance the flavor of chicken broth not gustatorily but olfactively.
