8E.2.1 Signal Recording and Processing in GC-Olfactometry

Generally speaking, the main purpose of the GC-O research is to list and rank the

aroma compounds present in the foodstuff according to their potential importance

in the food flavor. The ways in which these lists are built differ among the different

GC-O techniques, which can be classified into three broad categories:

1. Based on determination of threshold concentration: Aroma Extract Dilution

Analysis (AEDA) (Schieberle and Grosch 1987; Ullrich and Grosch 1987), and

Charm analysis (Acree et al. 1984)

2. Based on the measurement of the frequency of citations (Ruth et al. 1995; Pollien

et al. 1997)
