“Carbon Content of the C3 Cycle” is the method of choice used by the laboratories of the Ministry of Agriculture, Livestock and Supply in Brazil to identify exogenous sugar in juices. In a recent operation, 173,000 liters of juices and coconut water adulterated with 30% added sugars and water were discovered. The fraudulent products were seized and rendered unusable, and large fines are awaiting the offenders. The C3 photosynthetic cycle method has traditionally been used to detect added sugars in the winemaking process.
