| Popis: | The determination of residual solvents is critical for quality control in food production and manufacturing processes. A gas chromatographic and mass spectrometric detection (MSD) method was developed and validated to complement the static headspace flame ionization detection (FID) technique for identification, confirmation, and quantitation of solvent residues in botanicals, using Coffeeberry extract and pomegranate powder as test samples. Relative standard deviations (RSDs) of less than 12% were obtained for residual solvents in water and dimethyl sulfoxide. Coffeeberry extract supplemented with10 μg/g of Residual Solvents Class 3 Mix showed MSD and FID recoveries mainly of 91 to 121% and 77 to 110%, respectively, while those samples supplemented with 100 μg/g of Residual Solvents Class 3 Mix displayed MSD and FID recoveries of 105 to 123% and 87 to 112%, respectively. For pomegranate samples supplemented with 10 μg/g of Residual Solvents Class 3 Mix, MSD and FID recoveries of 95 to 124% and 72 to 151% were observed, respectively. Those samples supplemented with 100 μg/g of Residual Solvents Class 3 Mix exhibited MSD and FID recoveries of 109 to 135% and 97 to 127%, respectively. Thus, the developed procedure was demonstrated to be suitable for the analysis of residual solvents in natural food ingredients and is expected to find numerous industrial applications (e.g., process control and impurity detection in final products). |
