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 potassium bicarbonate good for you?

    In the small amounts used in foods, potassium bicarbonate (E501ii) is generally recognized as safe and can help reduce sodium compared with baking soda. Large amounts may raise blood potassium—people with kidney disease or on potassium‑sparing medications should avoid high intakes.

  2. Is potassium bicarbonate baking soda?

    No—baking soda is sodium bicarbonate (NaHCO3); potassium bicarbonate (E501ii) is a sodium‑free alternative used similarly as a leavening agent.

  3. What are the two sizes of potassium bicarbonate portable extinguishers?

    Common portable potassium bicarbonate (PKP) extinguishers are typically 18‑lb and 27‑lb units.

  4. Is potassium bicarbonate the same as baking soda?

    No—baking soda is sodium bicarbonate, while potassium bicarbonate (E501ii) is the potassium version and a sodium‑free substitute.

  5. What is potassium bicarbonate used for?

    In foods it functions as a leavening/raising agent, acidity regulator, and stabilizer, often as a sodium‑free alternative to baking soda. It’s used in baking powders, low‑sodium baked goods, and to reduce acidity in products like wine and cocoa.
