Abstract
Twenty-three samples of exotic fruits were purchased on the Hannover market and analysed for their sugar and acid contents.
Most samples contained glucose, fructose, and sucrose, but in persimmon, fig, and pomegranate hardly any sucrose could be detected.
Sorbitol was found only in Rosaceae.
Concentrations of total sugars (sum of 4 sugars) varied from 11 to 136 g·1-1. Concentrations of citric and malic acid varied considerably between species.
Soluble oxalic acid was detected in carambola only.
Although the gross amount of glucose related closely to concentrations of total sugars, some fruits deviated from the regression line.
Exotic fruits analysed in this study were tentatively classified by gross amount of glucose.
