Product Overview

L-Tartaric acid is a natural organic acid extracted from grape raw materials. As E334 food additive, it works as acidulant, pH regulator and sequestrant. It has a sharp, clean and refreshing sour flavour, faster to release sourness compared with citric acid. It can enhance fruit flavour, chelate metal ions and stabilize the whole food system. It is widely accepted in global food manufacturing.

Key Product Characteristics

1.Natural source from grapes, clean and refreshing sour taste

2.Fast sour release, strong flavour boosting effect

3.Excellent chelating property to bind metal ions, prevent discoloration and oxidation

4.Good water solubility, easy to dissolve and mix evenly

5.Stable physical and chemical properties under regular food processing conditions

6.Meets international food additive specifications for export

Main Functions

1.Acidulant & Flavor Enhancer Provide bright, refreshing sour taste, boost fruit aroma and enrich taste layers in food and drinks.

2.pH Regulator Adjust and stabilize pH value for food formulations.

3.Sequestrant Capture metal ions, inhibit oxidation and browning, extend shelf life of finished products.

4.Leavening Aid Cooperate with bicarbonate in baking powder to promote gas release for baked goods.

Application Scope

1.Beverages: Fruit juice, carbonated drinks, wine and functional drinks to adjust acidity and enhance fruit flavor.

2.Confectionery & Jelly: Hard candy, gummy candy and jelly, create bright sour taste and stabilize texture.

3.Baking Industry: Used in baking powder as leavening aid for cakes and pastries.

4. Other Food Processing: Seasonings, pickled food and canned goods for pH adjustment and anti-oxidation.

Packaging & Storage

Packaging: Standard food grade packaging

Storage Condition: Keep sealed in cool, dry and ventilated warehouse. Avoid moisture and high temperature.
