E200: Sorbic Acid (Antifungal Preservative) vs. E334: L-Tartaric Acid (Wine & Baking Acidulant)
Comparing 2 standards across 9 specifications. 9 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.
E334 (L(+)-Tartaric Acid) is a dicarboxylic organic acid recovered as potassium bitartrate by-product from wine barrels. INS 334, ADI has historically been set at up to 20 mg/kg bw/day by JECFA, delivering a sharp, lingering tartness in candies, soft drinks, and baking powders.

Functional Class

Preservative (Antifungal, Antimicrobial) | Acidity Regulator, Acidulant, Synergist for Antioxidants |
|
Acceptable Daily Intake (ADI)
|
11 mg / kg body weight per day (as sorbic acid) | Historically up to 20 mg / kg body weight per day (JECFA: 0–6 mg/kg unconditional + 6–20 mg/kg conditional acceptance) |
|
Chemical Formula
|
C6H8O2 | C4H6O6 (2,3-dihydroxybutanedioic acid) |
|
Primary Mechanism
|
Un-dissociated acid penetrates mold/yeast cell membranes, inhibiting enolase and dehydrogenase enzymes | Stronger sourness profile than citric acid (pKa1 2.98), stimulating salivation and activating baking soda |
|
Common Target Foods
|
Cheese wraps, baked pastries, dried fruits, fermented pickles, wine stabilization | Hard sour candies, baking powder (Cream of tartar), grape beverages, wine adjustment |
|
Dietary Compliance
|
100% Vegan (Chemical synthesis), Halal, Kosher | 100% Vegan (Wine by-product), Halal, Kosher |
