Tartaric acid dosage

Tartaric acid is a naturally occurring organic acid found primarily in grapes, bananas, tamarind, and other plants. It plays a central role in wine chemistry and many food and technical formulations. It is used as an acidifier, chelating agent, antioxidant, stabilizer, or pH regulator, depending on the sector.

Its presence and concentration directly influence the taste, preservation, chemical stability and microbiological quality of products. In oenology, it is one of the most widely used fixed acids, along with malic acid and citric acid.

Why measure tartaric acid?

The dosage of tartaric acid ensures quality control throughout the production chain, from raw material to final formulation. The objectives can be multiple:

• Balance acidity in wines, fruit juices or fermented drinks;
• Ensure regulatory compliance of food products where tartaric acid is used as an additive (E334);
• Evaluate the purity or stability of technical powder or liquid formulations;
• Monitor metabolic reactions in plant extracts used in nutraceuticals;
• Optimizing the sensory profile and conservation in the food industry or oenology.

Available analytical methods

YesWeLab offers several dosing techniques adapted to complex matrices:

• Acid-base titration: classic method for wines and musts, used in oenological laboratories;
• Ion exchange chromatography (IC): ideal for separating and quantifying tartaric acid in the presence of other organic acids;
• HPLC (High Performance Liquid Chromatography): widely used for food supplements, plant extracts or complex formulations;
• Colorimetric method: rapid method applicable to simple matrices.

The choice of method depends on the type of matrix, the expected concentration and the applicable regulatory or normative requirements.

Frequently analyzed matrices

Tartaric acid analyses are common in:

• Grape musts and wines (red, white, rosé, sparkling): for acid balance and sensory profile;
• Fermented or non-alcoholic drinks: quality control;
• Fruit juices, syrups and concentrates;
• Food supplements based on grapes, tamarind or organic acids;
• Food additives and technical ingredients (powder formulations, preservatives).

Recommended Related Analyses

To refine the acid-base profile or characterize plant extracts and formulations, it is relevant to combine this dosage with other analyses from the YesWeLab catalog:

• Malic acid determination : to characterize fermented musts or juices;
• Citric acid determination : to identify organic acid mixtures in food products;
• Determination of total polyphenols and tannins : for the sensory evaluation of wines and plant extracts.
