Rapid Detection of Gum-Injected Meat by Low-Field Nuclear Magnetic Resonance
A new method was developed for the rapid detection of gum-injected meat.Authentic pork and adulterated pork samples injected with different types of gums such as xanthan gum,carrageenagn,gelatin and agar were detected by LFNMR (low-filed magnetic resonance) and the data were processed by principal component analysis (PCA).Rapid detection was based on the existing water distribution of meat samples.The PCA plots obtained showed clear discrimination between authentic pork and adulterated pork,among the different investigated gums and among different adulteration levels.In conclusion,LF-NMR combined with PCA enables rapid discrimination between authentic pork and adulterated pork.
