Overview

E339 - Sodium phosphates

Sodium phosphates (E339) are a group of sodium salts of phosphoric acid used to control acidity, hold moisture, and keep mixtures smooth. In foods, they help cheeses melt evenly, baked goods rise properly, and meat stay juicy. They appear on labels as monosodium, disodium, or trisodium phosphate.

E650 - Zinc acetate

Zinc acetate (E650) is a zinc salt of acetic acid. In food, it is mainly used as a source of zinc for fortification and may also help control acidity in certain formulas. It is approved in the European Union and is generally safe when intake stays within recommended limits.

Popular questions

How are sodium phosphates made?
They’re produced by neutralizing food‑grade phosphoric acid with sodium hydroxide, carbonate, or bicarbonate to the desired ratio to yield mono-, di-, or trisodium phosphate, then crystallizing (often as hydrates); condensed polyphosphates are made by dehydrating/condensing orthophosphates at elevated temperatures.
How do saline enema sodium phosphates work?
They act as hyperosmotic salts that draw water into the colon, increasing volume and stimulating peristalsis to trigger a bowel movement; improper use can cause fluid and electrolyte imbalances, so they should be used only as directed.
How does sodium aluminate react with phosphates?
In water, sodium aluminate hydrolyzes to Al(OH)3, which binds phosphate and precipitates it as insoluble aluminum phosphate (AlPO4), especially near neutral pH—this is the basis for phosphate removal in water treatment.
How many meq of sodium does sodium phosphates have?
It depends on the specific salt and hydration: anhydrous NaH2PO4 ≈8.3 mEq Na per gram, Na2HPO4 ≈14.1 mEq/g, and Na3PO4 ≈18.3 mEq/g (hydrates contain less per gram); a typical adult sodium phosphate enema contains about 190 mEq of sodium.
How many sodium phosphates are there?
There are three main orthophosphate salts used in foods—monosodium, disodium, and trisodium phosphate—listed as E339(i–iii), plus various hydrates and condensed (polyphosphate) forms.
