Lemon Fruit Acidity

Citrus x limon (L.) Osbeck

Lemon fruit acidity is a determining quality criterion measured by juice titration. Unlike other citrus fruits, the total acidity of a lemon often increases as it matures, reaching 7.6–8.3% in certain cultivars with a juice pH of 2.0–2.6.

In the reference 20 varieties crop Lemon, where this is mentioned in the description.

To assess lemon fruit quality, the titratable acidity method is used, with results expressed in grams of citric acid per 100 ml of juice or as a percentage. An important evaluation metric is the sugar-acid ratio, which reflects the balance between sugar content on the Brix scale and acid concentration.

During the ripening of lemon fruits, a specific dynamic is observed: in contrast to most citrus fruits, total acidity often increases. The pH value of lemon juice typically ranges from 2.0–2.6. Fruit acidity is used as a key indicator for determining harvest timing, as it directly influences fruit metabolism, transport, and long-term storage.
