Popular questions
  1. Is tartaric acid bad for you?

    No—L(+)-tartaric acid (E334) is approved for use in foods (e.g., EU E-number; FDA GRAS) and is considered safe at typical levels; very high intakes may cause stomach upset, and only the L(+)-form is used as an additive.

  2. What is tartaric acid used for?

    It’s used as an acidulant to add sourness and control pH, and as an antioxidant/sequestrant; it also partners with baking soda in leavening and is added to wine to adjust acidity.

  3. How much tartaric acid to add to wine?

    It depends on your must/wine’s pH and titratable acidity—bench trials are essential; as a rule of thumb, 1 g/L tartaric acid raises TA by about 1 g/L and can lower pH by ~0.1–0.3, with typical adjustments in the 0.5–2 g/L range subject to local regulations.

  4. What does tartaric acid do?

    It provides a sharp, tart flavor while regulating acidity, chelating metals, and limiting oxidation; in baking it reacts with sodium bicarbonate to release CO2, and in wine it helps set acid balance and stability.

  5. What foods have tartaric acid?

    It occurs naturally in grapes, wine, and tamarind (also in smaller amounts in some fruits), and as an additive it’s found in soft drinks, candies, jams/jellies, gelatin desserts, and baking powders/cream of tartar.

  1. Is disodium phosphate bad for you?

    Generally no—E339(ii) is an approved additive used at low levels; however, it contributes sodium and phosphate, so people with kidney disease or on phosphate‑restricted diets should limit it.

  2. What is disodium phosphate in food?

    It's the sodium salt Na2HPO4 (E339(ii)) used as an emulsifier, acidity regulator/buffer, stabilizer, sequestrant, humectant, and thickener.

  3. What is disodium phosphate used for?

    It emulsifies processed cheese, controls acidity, improves texture and moisture retention in dairy and meat products, and binds metal ions that can affect flavor and color.

  4. Is disodium phosphate safe?

    Yes—it's permitted by regulators (e.g., FDA GRAS; EU E339) and considered safe at typical food levels, though very high phosphate intakes are discouraged, especially for people with kidney problems.

  5. What does disodium phosphate do?

    It keeps mixtures smooth and stable, maintains pH, binds minerals to protect quality, and can help foods retain moisture and thickness.
