DIFFERENTIATION OF FRESH AND FROZEN/THAWED MEAT SAMPLES BY MID INFRARED SPECTROSCOPY ON LIQUID MEAT SAMPLES

摘要

The invention relates to a method for analysing a meat sample, wherein the method comprises providing a meat sample, and obtaining a liquid sample from the meat sample, measuring a sample optical value of the liquid sample in a spectral range of 4000 cm -1 to 400 cm -1 in a spectroscopy step, determining, in a comparison step, particularly in a computing step, a similarity value by comparing the sample optical value to at least one control optical value obtained from at least one control sample, wherein the control sample has been prepared from fresh meat, and/or from frozen and thawed meat, and assigning the meat sample to "fresh meat" or "frozen and thawed meat" based on the similarity value.
