Popular questions
  1. What is modified food starch?

    A group of plant-based starches that have been physically, enzymatically, or chemically treated to change how they behave in foods—improving thickening, stability, freeze–thaw performance, or emulsification (E1400–E1452).

  2. Is modified food starch gluten free?

    Often yes when sourced from corn, potato, tapioca, or rice; if it’s from wheat, it can contain gluten unless specially processed and labeled gluten-free. In the US/EU, wheat-derived modified starch must be declared as “wheat,” so check the allergen statement or a gluten-free claim.

  3. What is modified corn starch?

    Modified starch made from corn that’s been treated to improve thickening, stability, and resistance to heat, acid, or shear; commonly used in sauces, soups, dressings, and desserts.

  4. Is modified corn starch gluten free?

    Yes—corn is naturally gluten-free, and modified corn starch remains gluten-free; only potential cross-contact is a concern, so rely on allergen statements or a gluten-free label if needed.

  5. What is modified wheat starch?

    Starch from wheat that has been modified to alter its functionality (e.g., thicker, more stable or freeze–thaw tolerant); it may retain some gluten unless specifically purified and labeled gluten-free. “Wheat” must appear in allergen labeling in many regions.

  1. How does calcium carbonate neutralize stomach acid?

    Calcium hydrogen carbonate (E170ii) neutralizes stomach acid via an acid–base reaction: Ca(HCO3)2 + 2 HCl → CaCl2 + 2 CO2 + 2 H2O, raising gastric pH.

  2. When calcium carbonate is added to hydrochloric acid?

    Calcium hydrogen carbonate reacts with hydrochloric acid to effervesce (release CO2) and form calcium chloride and water: Ca(HCO3)2 + 2 HCl → CaCl2 + 2 CO2 + 2 H2O.

  3. How does calcium carbonate neutralize acid?

    Its bicarbonate ions consume H+ to form carbonic acid, which decomposes to CO2 and water, leaving a neutral calcium salt (e.g., CaCl2).

  4. Why does calcium carbonate dissolve in acid?

    Acidic H+ converts carbonate/bicarbonate into CO2 and water, removing carbonate from the solid and driving dissolution; calcium hydrogen carbonate itself is soluble in water.

  5. How does calcium carbonate reduce acid rain?

    Calcium hydrogen carbonate isn’t used to prevent acid rain, but carbonate/bicarbonate alkalinity neutralizes acidic waters; industrially, limestone or lime (not Ca(HCO3)2) scrubs SO2 from flue gases, reducing acid‑rain precursors.
