Abstract
We demonstrate infrared spectroscopy systems that are capable of predicting acrylamide level in powders of potato fries based on all-fiber high power supercontinuum (SC) lasers in both the short-wave and mid-wave infrared spectral range. Two SC lasers used in this study cover wavelength range of 670nm to 2500nm and 1600nm to 11000nm, respectively. We use the spectroscopy system to measure 32 French fry samples with different acrylamide concentrations calibrated by gas chromatography-mass spectroscopy (GCMS). Our predicted acrylamide concentrations show a good linear correlation to the measured acrylamide concentration obtained through GCMS, and the partial least square regression analysis shows standard error down to 145ppb. Based on our results, our system could provide a non-destructive alternative method for determining the acrylamide in food samples at a stand-off distance, which could be important for near-line or in-line quality control purposes.
