Question 2: No flavor analysis was done! Only headspace
analysis. They are very different.
Thanks for your helpful comments. In the revised version of page 16,
”3.5 Determination of flavor”, the flavor analysis was carried out by
headspace sampling using Flavour Spec®, Gesellschaft für Analytische
Sensor systemembH, Dortmund, Germany. The flavor analysis was performed
by headspace injection using Flavour Spec®, Gesellschaft für Analytische
Sensor systemembH, Dortmund, Germany. To avoid misunderstanding, the
term ”headspace vial” has been replaced with ”headspace sample vial”
throughout the text.
