Overview

E501 - Potassium carbonates

Potassium carbonates (E501) are white, alkaline salts used to control acidity and help baked goods rise. The group includes potassium carbonate and potassium bicarbonate. They are common in “cocoa processed with alkali” and in some low‑sodium baking mixes.

E504 - Magnesium carbonates

Magnesium carbonates (E504) are mineral-based additives that help powdered foods flow and mix evenly. They act mainly as anti-caking agents and carriers, and sometimes as mild acidity regulators. You may spot them in table salt, spice mixes, powdered drinks, and chewing gum.

Popular questions

Flake8 e501 line too long how to fix?
In food labeling, E501 refers to potassium carbonates, a permitted pH regulator/stabiliser; there's nothing to fix, but you can avoid it by choosing products without E501 on the label.
How does potassium carbonates structure allow it to perform its function?
As an ionic salt (K2CO3/KHCO3), it dissociates in water to potassium and carbonate/bicarbonate ions, creating alkalinity and buffering pH. The carbonate reacts with acids to release CO2, aiding leavening and stabilizing textures.
How to avoid e501 line too long?
To avoid E501 in foods, check ingredient lists and pick products labeled additive‑free or without potassium carbonates. In recipes, use alternatives like sodium bicarbonate (E500), baking powder, or yeast depending on the application.
How to fix e501 errors?
If a recipe tastes overly alkaline from potassium carbonates, reduce the amount and balance with an acid (e.g., cream of tartar, lemon juice, or acidic dairy), or substitute a milder leavening/pH regulator like baking powder.
How to fix e501 errorsi n python?
E501 in food labeling is potassium carbonates, an approved pH regulator/stabiliser; if you meant the Python lint rule E501, that’s unrelated to food additives.
