Comparing:
E200: Sorbic Acid (Antifungal Preservative)
E290: Carbon Dioxide (Carbonation & MAP Gas)
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.
E290 (Carbon Dioxide / CO2) is an authorized food additive functioning as a carbonating gas, modified atmosphere packaging (MAP) preservative, and cryogenic freezing propellant. INS 290, ADI is Not Limited (Quantum Satis).
