Comparing:
E330: Citric Acid (Universal Acidulant / Chelator)
E635: Disodium 5'-Ribonucleotides (I+G Blend)
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.
E635 (I+G) is a standardized 50/50 co-crystallized blend of disodium inosinate (E631) and disodium guanylate (E627). INS 635, ADI is Not Specified, serving as the commercial standard umami booster in global food manufacturing.
