Comparing:
E330: Citric Acid (Universal Acidulant / Chelator)
E501: Potassium Carbonate (Potash / Alkaline Noodle Salt)
E330 (Citric Acid) is a tricarboxylic organic acid produced by industrial fermentation of Aspergillus niger on carbohydrate substrates. INS 330, ADI is Not Limited (Quantum Satis), the single most widely used acidulant, flavor enhancer, and metal chelator on Earth.
E501 (Potassium Carbonates / K2CO3) is an inorganic alkaline mineral salt. INS 501(i), ADI is Not Limited (Quantum Satis), used as the key 'Kansui' alkaline agent in Japanese ramen noodles and in the Dutch processing of cocoa powder.
