The amount of juice in the cane varies according to district of origin and degree of maturity. About 60 to 80 per cent of the juice is extracted by the methods described and the juice conforms approximately to the following analysis ... 

Carbon stable isotope ratio (CSIR) analysis of sugar utilizing an isotope ratio mass spectrometer (IRMS) is routinely used to detect the addition of cane sugar and corn syrup to most juices with the exception of pineapple. The inability of CSIR analysis to detect beet sugar in orange and apple juices because of metabolic similarities between adulterant and authentic products has required alternative methods, e.g., combination of IRMS and nuclear magnetic resonance (NMR) spectroscopy. The method requires the determination of five isotope ratios after fermentation of the juice the H/ H and iSq/ISo ratios of the fermentation water plus the total C/ C and H/ H ratios on the methyl and methylenic groups of the alcoholic distillate.
