E200: Sorbic Acid (Antifungal Preservative) vs. E440: Pectin (Citrus & Apple Jam Gelling Fiber)
Comparing 2 standards across 10 specifications. 10 key differences identified.
E200 (Sorbic Acid / 2,4-hexadienoic acid) is an unsaturated organic carboxylic acid preservative with broad antifungal and antimold activity. INS 200, group ADI is 11 mg/kg bw/day (expressed as sorbic acid), active across acidic and neutral pH up to 6.5.
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.
