Description
Tartaric Acid is a natural organic acid occurring abundantly in grapes, presented as colorless crystals or white crystalline powder. The L(+) form is the classic wine-derived acidulant, prized for its sharp, clean sourness and its ability to form stable salts with calcium and potassium - properties that make it essential in baking powder, where it regulates gas release. It controls pH, enhances fruit flavors and stabilizes color in a wide range of foods and beverages. Its sodium and potassium salts extend its utility in emulsification and metal chelation. Produced to FCC specifications with a two-year shelf life, it offers a dependable, naturally positioned acidulant for food, beverage and pharmaceutical applications worldwide. It also serves as a precursor for cream of tartar and other tartrate derivatives used in baking. It is packed in 25 kg bags and keeps for two years in a cool, dry place. The product is the L(+) form with a specific optical rotation in the +12.0 to +13.0 degree range, confirming its natural-handed structure. In practice it is metered into baking powder blends where its controlled gas release gives bakers a predictable rise, and into grape-based drinks where it authenticates the fruit-acid profile. It also stabilizes egg-white foams in meringues. The product is manufactured under strict hygiene controls with documented test results for purity, heavy metals and microbial safety, ready for audit when customers require. How Tartaric Acid works: tartaric acid is a dicarboxylic acid that forms stable salts with potassium and calcium, properties that no other common acidulant shares. In baking powder these salts control exactly when carbon dioxide releases, giving bakers the predictable rise they depend on. In wine and grape products the L(+) form is the natural fruit acid, authenticating the flavor. Its sharp, clean sourness enhances fruit flavors and stabilizes color in jams and beverages. Practical guidance: meter it into baking powder and leavening blends for controlled gas release; adjust acidity and stabilize wines and grape drinks; sharpen fruit candies, jellies and beverages; set texture in jams; and use it in effervescent tablets. Quality assurance: produced to FCC specifications from grape-derived and synthetic routes, with content, specific rotation, oxalate and heavy-metal testing per batch, documented for buyers. Packed in 25 kg bags with a two-year shelf life in cool, dry storage. For bakers and beverage makers, tartaric acid is the acidulant with unique, irreplaceable functionality. Specification highlights: it is packed in 25kg/bag with a minimum order quantity of 1000kg. Certificates of analysis accompany every shipment, and sample supply, specification customization and flexible payment terms are available for qualified buyers, supported by the standardized seven-step service process from inquiry to after-sales support. Documented quality from batch to batch: every production lot is verified against the full specification - identity, purity, heavy metals and microbiology - before release, and the resulting certificates and batch records travel with each shipment to support qualification and audit. Raw materials are sourced to defined standards, storage follows the conditions stated in the specification, and the product ships in its original, intact packaging. Shelf life and storage requirements are clearly documented, so purchasing, warehouse and quality teams all work from the same reference. This repeatable quality system is what makes the grade dependable for multi-year supply agreements.
Applications
It is a key component of baking powder and leavening systems, controlling the rate of gas release for consistent rise. Winemakers use it to adjust acidity and stabilize wine, and beverage makers use it in effervescent drinks, fruit drinks and candies for sharp fruit-accented sourness. Confectionery, jams and jellies use it to balance sweetness and set texture, and pharmaceuticals use it in effervescent tablets.
Advantages
Its grape-derived natural origin and clean, sharp sourness give products an authentic fruit-acid profile that synthetic acidulants cannot fully replicate. Its leavening control in baking powder makes it functionally irreplaceable in that application. FCC compliance, a two-year shelf life and dependable supply make it a reliable core acidulant for quality-focused manufacturers.
