Detection of exogenous sugars in pineapple juice using compound-specific stable hydrogen isotope analysis

Abstract An improved procedure for determining 2H/1H isotope ratios, using gas chromatography-isotope ratio mass spectrometry, has been used to detect the addition of exogenous C4-plant-derived sugars to pineapple juice. Isotopic techniques are commonly used to identify the addition of low-cost suga...
