Citrus fruit acidity

Citrus L.

The acidity of citrus fruits is determined by the titratable concentration of citric acid in the juice. This is a key quality indicator that determines flavor, harvest timing, and fruit shelf life.

In the reference 16 varieties crop Citrus, where this is mentioned in the description.

In citrus cultivation, titratable acidity, expressed as a percentage of citric acid per volume or mass of juice, is used to assess fruit quality. Acidity levels vary significantly by species: lemons typically range from 3.5% to 8.1%, while oranges and mandarins range from 0.6–2.0% and 0.9–1.2%, respectively.

The acidity index is dynamic and decreases as the fruit matures, concurrent with sugar accumulation. To determine ripeness, the sugar-acid ratio is used, representing the proportion of sugar content to titratable acidity; its optimal values generally fall within the 12–30 range. High acidity also contributes to better fruit storage by inhibiting the development of certain pathogens.
