Popular questions
What is e331 in food?
E331 is sodium citrates—the mono-, di-, and trisodium salts of citric acid—used mainly as acidity regulators/buffers, sequestrants, and emulsifying salts in foods like soft drinks and processed cheese.
How are sodium citrates used in molecular gastronomy?
They’re used to adjust and buffer pH, chelate calcium, and act as an emulsifying salt—commonly to make ultra-smooth, meltable cheese sauces and to tune acidity/calcium levels for techniques like spherification and stabilizing foams.
What are sodium citrates degradation byproducts?
Under normal food use they’re stable; with strong heating/combustion they decompose to carbon oxides (CO2/CO) and sodium oxides (and related inorganic residues).
Why does sodium citrates burn?
It isn’t flammable; any “burning” sensation typically comes from irritation of skin, eyes, or mouth at high concentrations due to its mildly alkaline, saline nature, and on heating it decomposes rather than sustaining a flame.
How much sodium sesquicarbonate added to laundry sop?
As a laundry booster, use about 1–2 tablespoons (15–30 g) per standard load; in a DIY powder detergent, it’s typically 5–15% of the formula by weight. Dissolve well and avoid use on wool or silk.
How ro clean bronze with sodium sesquicarbonate?
Conservators often use a 5% w/v solution (about 50 g per liter of deionized water) to soak bronze affected by “bronze disease,” changing the solution periodically until activity ceases, then rinse, dry thoroughly, and apply a protective coating. Always test on a small area first and avoid prolonged contact with sound patina.
How to make sodium sesquicarbonate?
Combine equimolar sodium carbonate (washing soda) and sodium bicarbonate (baking soda) in water—e.g., 106 g Na2CO3 with 84 g NaHCO3—then allow the double salt to crystallize, filter, and dry. For food applications, purchase certified-grade material rather than making it at home to ensure purity and composition.
Is sodium sesquicarbonate safe?
Yes—E500(iii) is an approved food additive used as an acidity regulator/raising agent and is considered safe at typical use levels; it mainly contributes sodium and alkalinity. Excess exposure can irritate eyes/skin or upset the stomach, so handle the powder carefully and follow normal use levels.
Sodium sesquicarbonate what is it used for?
In foods (E500iii) it serves as an acidity regulator, buffer, and leavening agent. Beyond food, it’s used as a detergent builder/water softener, mild alkaline cleaner, pH buffer in baths, and in conservation treatments for bronze.
