Abstract
A solid-phase microextraction procedure followed by analysis by gas chromatography is proposed to determine total flavouring content in encapsulated flavouring. The method showed a good selectivity, as well as good intraday and interday precision, CVs = 1 % in both cases. The calibration curves were linear at the tested ranges (R = 0.998). The limits of detection and quantification were 17 and 48 g kg−1, respectively. Good recoveries were obtained (95.9–105.4 %). In the ruggedness test, sample temperature, extraction time, sample amount, magnetic stirring and desorption temperature were the factors that stood out as the causing of the greater effects on the analytical results. These results present a solid-phase microextraction (SPME) methodology, which may be applied as a quality control tool for industrial laboratories.
