Steeping into the World of Tea with Raman

Raman spectroscopy is a promising technique in food science due to its ability to provide rapid and non-destructive analysis of samples. For instance, we have previously explored the Raman spectra of olive oils using the B&W Tek i-Raman® Plus-785 system (Fast Ingredient Analysis of Edible Oils Using a Portable Raman Spectrometer). Regular Raman spectroscopy can be applied to investigate properties of traditional/herbal tea, and when Raman is coupled to SERS technology it can be used to detect trace pesticides (ug level) on tea leaves (Trace Detection of Paraquant in Tea Leaves)… Continue reading
