Camu-camu fruit, a fantastic source of vitamin C

The vitamin C content of three samples of camu-camu collected in the east of Roraima State, Brazil, was analyzed. One sample was from the Maú river, the other two (an isolated plant and another population) were from the Urubu river, both of these, rivers being tributaries of the river Tacutu. Acid ascorbic was determined by HPLC. The fruits form an individual plant on the Urubu river presented the highest concentration of ascorbic acid, 6112±137.5 mg in 100g of pulp. The populations of camu-camu from the Urubu and Maú rivers presented ascorbic acid concentrations of 5737±236.1 mg (pulp + rind) and 3571±12.0 mg per 100g, respectively. This unprecedented finding shows the need for further studies, considering the genetic variability of camu-camu and its nutritional potential as a source of vitamin C.
