Tag: Citric acid content

Organic acids constitute about 0.4–1.0% of a potato's fresh weight, and citric acid is the most abundant of these. This means that yes, citric acid is in potatoes, but its concentration is significantly lower compared to fruits like lemons.

According to the Food and Drug Administration, lemons and limes are consistently the most acidic citrus fruits, with a pH of around 2.0 to 2.6, making them significantly more acidic than grapefruits. Grapefruits, while still acidic, have a higher pH level, resulting in a less intense sourness that many people find more palatable. This difference in acidity impacts how each fruit is used in cooking and how it affects our bodies, from dental health to digestion.

According to scientific research, lemons and limes contain the highest amount of naturally occurring citric acid among fruits. This organic acid is responsible for the distinct sour and tart flavor in many citrus varieties, playing a key role in both their taste profile and nutritional properties.
