摘要
Aroma extract dilution analysis (AEDA) was performed on an extract prepared from chicken soup stock and 9 aroma-active compounds were selected. On the basis of high flavor dilution (FD) factors in combination with the results of the identification experiments, methylpyrazine, 2-ethyl-4-methylthiazole, 3-(methylthio)propanal, and (E,E)-2,4-decadienal were suggested as primary aroma compounds of chicken soup stock. Recombination and omission experiments of the identified aroma-active compounds in taste-reconstituted chicken soup stock revealed the main flavor profile of each compound as "roast", "roast meaty", "boiled meaty", and "fatty", respectively. A comparison of the overall flavor of the recombined mixture and the chicken soup stock revealed a high similarity, suggesting that these four compounds are important contributors to the aroma of chicken soup stock.
