E260: Acetic Acid (Vinegar Acidulant / Preservative) vs. E440: Pectin (Citrus & Apple Jam Gelling Fiber)
Comparing 2 standards across 10 specifications. 9 key differences identified.
E260 (Acetic Acid / Ethanoic acid) is a natural carboxylic acid produced via aerobic Acetobacter fermentation of ethanol. INS 260, ADI is Not Limited (Quantum Satis), giving vinegar its characteristic pungent sour flavor and pickling preservative action.
E440 (Pectin) is a complex heteropolysaccharide rich in alpha-(1->4)-linked D-galacturonic acid extracted from citrus peels and apple pomace. INS 440, ADI is Not Limited (Quantum Satis), the global gold standard gelling agent for jams, jellies, and fruit spreads.
