Analysis of Fermented Red-Yeast Rice Products Using Femtosecond Laser Ionization Mass Spectrometry.

Area of Science:

• Food Science
• Analytical Chemistry
• Toxicology

Background:

• Dietary supplements, including fermented red-yeast rice products, are widely consumed for health benefits.
• Serious adverse health events have been linked to contaminated fermented red-yeast rice supplements.
• Ensuring the safety and quality of commercial food products is a critical public health concern.

Purpose of the Study:

• To investigate the chemical composition of contaminated and non-contaminated fermented red-yeast rice dietary supplements.
• To evaluate the utility of gas chromatography combined with femtosecond laser ionization mass spectrometry (GC-fsLIMS) for detecting contaminants in dietary supplements.
• To establish the potential of GC-fsLIMS as a quality assurance tool for commercial food products.

Main Methods:

• Samples of fermented red-yeast rice dietary supplements, both contaminated and non-contaminated, were analyzed.
• Gas chromatography combined with femtosecond laser ionization mass spectrometry (GC-fsLIMS) was employed for precise chemical analysis.
• Quantitative measurements of various chemical species were performed in both sample types.

Main Results:

• GC-fsLIMS analysis revealed the presence of several chemical species at elevated concentrations in the contaminated supplement sample compared to the non-contaminated sample.
• The study successfully identified specific chemical markers associated with contamination in the fermented red-yeast rice product.
• The sensitivity and specificity of GC-fsLIMS for detecting these chemical variations were demonstrated.

Conclusions:

• The comprehensive analysis using GC-fsLIMS is a powerful method for identifying contaminants in dietary supplements.
• This analytical technique holds significant potential for ensuring the quality and safety of commercial food products.
• Implementing GC-fsLIMS can help prevent serious health hazards associated with adulterated food supplements.
