Abstract SNIF-NMR is one of the analytical methods used to discriminate impurities in food and natural products. To determine the origin of compounds, SNIF-NMR utilizes frequency of deuterium in site specific fractionated sample using nuclear magnetic resonance. Also, SNIF-NMR is currently used to evaluate the authenticity of various foods such as wine, vanillin and oil, and is known to provide more accurate information than other analytical methods. In this review, the basic principles and practical examples of SNIF-NMR is presented.

 

Keywords Deuterium, natural isotope fractionation, SNIF-NMR
