Popular questions
  1. Is citric acid bad for you?

    At typical food levels, citric acid (E330) is considered safe by major regulators (GRAS; EFSA/JECFA). Concentrated or frequent acidic exposure can irritate the mouth/stomach or contribute to tooth enamel erosion.

  2. Where does the citric acid cycle occur?

    In eukaryotic cells it occurs in the mitochondrial matrix; in bacteria it occurs in the cytosol.

  3. What does citric acid do to your body?

    It is a normal intermediate in energy metabolism and is readily metabolized to carbon dioxide and water. Citrate can bind minerals, which may enhance absorption of some and help prevent certain kidney stones by increasing urinary citrate.

  4. Where does citric acid come from?

    It occurs naturally in citrus fruits, but most food-grade citric acid is produced by fermenting sugars (e.g., from corn, beet, or cane) with Aspergillus niger.

  5. How is citric acid made?

    Industrially, sugars are fermented with Aspergillus niger to produce citric acid, then it is recovered and purified—often by precipitating calcium citrate and converting it back with sulfuric acid or via ion-exchange/crystallization.

  1. Buying caustic soda, how to use it to dissolve alum?

    E521 (aluminium sodium sulphate, “alum”) is readily soluble in plain water; you don’t need caustic soda, and mixing it with sodium hydroxide can cause an alkaline reaction and is not appropriate for food use.

  2. Cinema modeoff how to repair a 12 volt battery for under 5 dollars using alum and baking soda?

    E521 is a food-grade leavening acid used in baking powders and water treatment, not intended for battery repair; using “alum” in lead–acid batteries is unsafe and not recommended.

  3. Dell dimension e521 how remove a firewire pci card?

    E521 here refers to aluminium sodium sulphate, a food additive used as an acid in baking powder, and is unrelated to computer hardware.

  4. Dell dimension e521 when to replace battery?

    E521 is the EU code for aluminium sodium sulphate, a food additive, not a device model, so it has nothing to do with batteries.

  5. E521 how to know if a comic is updated?

    E521 denotes aluminium sodium sulphate in the EU additives list and isn’t related to comics or apps; I can help with its food uses or safety if needed.
