This instrument can perform a high-sensitivity qualitative and Analysis of Flavor and Fragrance Components Using the FFNSC 3 Library
quantitative analysis of highly volatile components including
the fragrance components in food products. Flavor and fragrance components in samples were scanned using GC/MS, and then subjected to a similarity search using the FFNSC 3 library,
enabling them to be identified. Flavor and fragrance components can be identified with high accuracy by using this library, which contains
High-Speed Performance information on 3,462 flavor and fragrance compounds.
It is equipped with the functions needed for high-speed
analysis, and can improve both throughout and productivity. Similarity Search Using the FFNSC 3 Library
Excellent Versatility
With simple operations and no need for special pretreatment, a Headspace Analysis System
variety of samples from solids to liquids can be analyzed. With this analysis system, a sample is placed in a vial, which is then
sealed and heated for a set period. The volatile components that are
expelled in the gas phase are taken into the instrument, loaded into a
gas chromatograph or gas chromatograph mass spectrometer, and
separately detected. 100 % 178

Source: Shimadzu Application News No. M271.
In the analysis of food product samples involved in off-flavor complaints, it was confirmed that four components are more often found in off-flavor
products than in normal products. The four components detected were further analyzed using the off-flavor analysis database, and concentration and
odor threshold values as well as odor characteristics were confirmed. From the results, 2,4,6-trichloroanisole was identified as an odor-causing substance.
