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. What is the formula for magnesium phosphate?

    For the food additive E343(i) monomagnesium phosphate, the formula is Mg(H2PO4)2 (often found as hydrates); the fully basic “magnesium phosphate” is Mg3(PO4)2.

  2. What does monobasic mean?

    Monobasic means only one acidic hydrogen per acid unit is replaced by a metal; in phosphates it refers to dihydrogen phosphate salts (H2PO4−), such as Mg(H2PO4)2.

  3. What is magnesium ascorbyl phosphate?

    It’s a stabilized vitamin C (ascorbic acid) derivative used mainly in cosmetics and skincare; it is different from the food additive magnesium phosphates (E343).

  4. What is the molar mass of magnesium phosphate?

    Anhydrous monomagnesium phosphate, Mg(H2PO4)2, is about 218.28 g/mol; the tribasic magnesium phosphate Mg3(PO4)2 is about 262.86 g/mol (hydrate forms will differ).

  5. Why boric acid is monobasic acid?

    In water, boric acid B(OH)3 acts as a Lewis acid that accepts one OH− to form B(OH)4−, effectively releasing only one proton equivalent, so it is monobasic.
