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.
What is monopotassium phosphate used for?
In foods (E340i) it’s used as an acidity regulator/buffer, emulsifying and stabilizing salt, humectant and thickener, and as a source of potassium and phosphate.
Is monopotassium phosphate an electrolyte?
Yes—it's a salt that dissociates into potassium (K+) and phosphate ions in water, so it acts as an electrolyte and is used to adjust mineral content and pH.
What does monopotassium phosphate do to the body?
It provides potassium and phosphate: potassium supports nerve and muscle function and fluid balance, while phosphate supports energy metabolism (ATP) and bone; normal food levels are safe, but people with kidney disease should avoid excessive intake.
What is potassium phosphate monobasic?
It’s another name for monopotassium phosphate (KH2PO4), the monobasic salt of phosphoric acid approved as food additive E340i.
Cannabis when to foliar feed with monopotassium phosphate?
Growers typically apply it as a dilute foliar spray in early bloom or to correct P/K deficiencies, at lights-off or cooler times; avoid spraying buds or late flower to reduce residue and mold risk.
