Comparing E500 - Sodium carbonates vs E170I - Calcium carbonate

Overview

E500 - Sodium carbonates

Sodium carbonates (E500) are a group of salts that include sodium carbonate, sodium bicarbonate (baking soda), and sodium sesquicarbonate. They help dough rise, balance acidity, and keep certain foods stable during processing. Regulators in the EU have set clear specifications for their identity and purity when used in food.

E170I - Calcium carbonate

Calcium carbonate (E170i) is a white mineral often called chalk. In food it is used to give a bright white color, to stabilize acidity, and to add calcium. It is widely allowed in the United States and the European Union when used in normal amounts.

Popular questions

  1. How to reset olympus e500?

    On food labels, E500 refers to sodium carbonates (sodium carbonate/bicarbonate), an acidity regulator and leavening agent; it’s unrelated to the Olympus E‑500 camera.

  2. What is e450 and e500?

    E450 are diphosphates (emulsifying salts and leavening agents), while E500 are sodium carbonates (sodium carbonate/bicarbonate) used mainly as acidity regulators, leavening agents, and anti-caking agents.

  3. 2003 e500 mercedes benz how to move electric front seat manual?

    E500 in foods means sodium carbonates, not a Mercedes model; as an additive it regulates pH and helps dough rise.

  4. 2003v e500 w211 how to add brake fluid?

    E500 on ingredient lists denotes sodium carbonates, a pH regulator and raising agent, and is unrelated to automotive brake fluid.

  5. E500 wagon what chassis?

    In food labeling, E500 is sodium carbonates (sodium carbonate/bicarbonate), unrelated to vehicle chassis designations.

  1. What is chalk made of?

    Traditional chalk is mostly calcium carbonate (CaCO3), a naturally occurring mineral; some modern blackboard “chalk” sticks may instead use calcium sulfate (gypsum).

  2. What is chalk paint?

    It’s a matte decorative paint that uses calcium carbonate as a white pigment/filler to create a chalky, velvety finish with good coverage and adhesion.

  3. How to make chalk paint?

    Stir calcium carbonate powder into a little water to make a slurry, then mix it into latex/acrylic paint—about 2–3 tablespoons calcium carbonate per 1 cup of paint—adjusting to reach the desired texture and coverage.

  4. Can you eat chalk?

    Food‑grade calcium carbonate (E170i) used in foods and supplements is considered safe at permitted levels, but eating non‑food‑grade chalk sticks isn’t advised and excessive intake can cause constipation or high‑calcium effects.

  5. What is calcium carbonate used for?

    In foods, E170i is used mainly as a white colorant and stabilizer and as a source of calcium; beyond food, it’s common in antacids and as a filler/pigment in tablets, paints, paper, and plastics.
