E334: L-Tartaric Acid (Wine & Baking Acidulant) vs. E410: Locust Bean Gum (Carob Bean Gum / LBG)
Comparing 2 standards across 10 specifications. 10 key differences identified.
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.
E410 (Locust Bean Gum / LBG) is a galactomannan polysaccharide milled from the seeds of the carob tree (Ceratonia siliqua). INS 410, ADI is Not Limited (Quantum Satis), providing smooth melt-down and freeze-thaw ice crystal inhibition in premium ice creams.

Acidity Regulator, Acidulant, Synergist for Antioxidants | Thickener, Stabilizer, Syneresis Inhibitor |
|
Acceptable Daily Intake (ADI)
|
Historically up to 20 mg / kg body weight per day (JECFA: 0–6 mg/kg unconditional + 6–20 mg/kg conditional acceptance) | Not Limited (Quantum Satis) |
|
Primary Mechanism
|
Stronger sourness profile than citric acid (pKa1 2.98), stimulating salivation and activating baking soda | Synergistically cross-links with xanthan gum and carrageenan to form elastic gels and halt ice crystallization |
|
Common Target Foods
|
Hard sour candies, baking powder (Cream of tartar), grape beverages, wine adjustment | Ice creams (prevents icy graininess), cream cheeses, infant formula thickeners, fruit sauces |
