L’acide citrique est principalement produit par fermentation de la mélasse de betterave ou de canne à sucre, en privilégiant l’aspergille noire comme moisissure. Après fermentation, l’acide citrique est séparé de la solution par précipitation en utilisant le citron vert ou le carbonate de calcium, puis par filtration. Le citrate de calcium est lavé puis solubilisé avec de l’acide sulfurique pour constituer de l’acide citrique brut tandis que le calcium précipite en CaSO4 (gypse) et est éliminé par filtration. Enfin, l’acide citrique brut est décoloré et déminéralisé pour répondre aux normes de qualité alimentaire.
