ABSTRACT
Objective:
To determine phenolphthalein illegally added into diet health products by Raman spectroscopy.Methods:
Raman spectroscopy was used to determine phenolphthalein added into diet health products. The diet health products were extracted by suitable solvents, and then the extracting solution was measured by Raman spectroscopy.Results:
A calibration curve was built and the analysis was performed on the samples with phenolphthalein at different concentrations. The results were accordance with the real added amount.Conclusion:
With simple sample preprocessing method, Raman spectroscopy can be used in the fast detection of phe-nolphthalein illegally added into diet health products. The method is fast and simple with low cost, and can provide both qualitative and quantitative results. The detection limit is 1% for phenolphthalein in diet health products.
