Overview

E330 - Citric acid

Citric acid (E330) is a tart, sour-tasting acid found naturally in citrus fruits and used widely in foods and drinks. It helps control acidity, keeps flavors bright, and protects color and freshness in many products.

E1505 - Triethyl citrate

Triethyl citrate (E1505) is a clear, almost odorless liquid made by combining citric acid with ethanol. In foods, it works mainly as a carrier for flavors and colors, a mild emulsifier, and a plasticizer that helps coatings stay flexible.

Popular questions

Is citric acid bad for you?
At typical food levels, citric acid (E330) is considered safe by major regulators (GRAS; EFSA/JECFA). Concentrated or frequent acidic exposure can irritate the mouth/stomach or contribute to tooth enamel erosion.
Where does the citric acid cycle occur?
In eukaryotic cells it occurs in the mitochondrial matrix; in bacteria it occurs in the cytosol.
What does citric acid do to your body?
It is a normal intermediate in energy metabolism and is readily metabolized to carbon dioxide and water. Citrate can bind minerals, which may enhance absorption of some and help prevent certain kidney stones by increasing urinary citrate.
Where does citric acid come from?
It occurs naturally in citrus fruits, but most food-grade citric acid is produced by fermenting sugars (e.g., from corn, beet, or cane) with Aspergillus niger.
How is citric acid made?
Industrially, sugars are fermented with Aspergillus niger to produce citric acid, then it is recovered and purified—often by precipitating calcium citrate and converting it back with sulfuric acid or via ion-exchange/crystallization.
