This article introduces a method for analyzing the odor of mineral water using solid phase microextraction (SPME) and gas chromatography/mass spectrometry (GC/MS). The samples were analyzed using multivariate analysis software (Mass Profiler Professional), and 26 components with statistically significant differences were selected. This method can extract components that are difficult to confirm through chromatogram comparison, making it useful for identifying the causes of odor.
This document details an analysis of off-flavors in mineral water. The method involves headspace solid-phase microextraction (SPME) followed by gas chromatography/mass spectrometry (GC/MS). The resulting data is processed using Agilent's Mass Profiler Professional software to identify statistically significant differences between samples with added off-flavor compounds and control samples. This manual is written in Japanese.
The analysis requires a minimum of 3 samples.
The extraction time is 30 minutes.
The injection port temperature is 270 degrees Celsius.
