Tartaric Acid

Tartaric acid is a naturally occurring dihydroxy dicarboxylic acid, found in grapes and recovered from wine-making by-products; the commercial food grade is normally the L-(+) form. Nustras supplies it as a white crystalline powder, an acidulant for the food, beverage and supplement sectors.

Tartaric acid is formulated into beverages and drink powders, confectionery and sour coatings, baking powders and leavening systems, effervescent tablets and powders, and into supplement tablets as an acidulant, pH regulator and sequestrant.

The material is a white, odourless crystalline powder, freely soluble in water. Assay, specific optical rotation, loss on drying, sulfated ash are standardised to specification and determined by titration and the compendial tests of the applicable pharmacopoeia; identity is confirmed by infrared spectroscopy, and heavy-metal and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis. CAS 526-83-0, molecular formula C4H6O6, molecular weight 150.09.

Nustras supplies tartaric acid in bulk commercial quantities, in food-grade bags and fibre drums, to manufacturers and formulators internationally, with a certificate of analysis, specification sheet and country-of-origin documentation on every lot. Tartaric acid (E334 / INS 334) is an accepted food additive and supplement excipient in major markets; buyers confirm the permitted grade and use level for their application.
