Identification and Quantification of Potential Adulterants in Cranberry Fruit Juice Dry Extracts using Absorbance-Transmittance Excitation-Emission (A-TEEM) Spectroscopy

Identification and Quantification of Potential Adulterants in Cranberry Fruit Juice Dry Extracts

Unscrupulous dietary supplement suppliers may adulterate cranberry with cheaper ingredients that mimic the analytical signature in conventional assays

The Aqualog A-TEEM spectrometer has the capacity to specifically identify and sensitively quantify key adulterants that are most commonly detected in Cranberry dietary supplements, including Pine Bark, Grape Seed and Peanut Skin extracts. Compared to other more expensive and time-consuming analytical methods, the A-TEEM technique exhibits up to an order of magnitude or more higher sensitivity (≤1%) and reduction in analysis time (less than 1 minute). The analyses and reporting can also be automated for use in laboratory operations in near real-time. Thus, A-TEEM spectroscopy should be considered a valuable technique for developing product specific methods for identity and composition required for cGMP as well, and for adulterant detection in the food and dietary supplement industry.
