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.
Is sodium tripolyphosphate bad for you?
Not at the low levels used in foods; regulators consider it acceptable within set limits, though very high intakes of phosphate additives may be a concern—especially for people with kidney disease or those advised to limit phosphorus.
What is sodium tripolyphosphate used for?
It’s added as a sequestrant and stabilizer to improve water retention, texture, and juiciness—commonly in seafood, meats, and poultry—and also helps emulsify and reduce drip loss.
How to remove sodium tripolyphosphate from fish?
You can reduce surface residues by rinsing and briefly soaking the fish in cold water (e.g., 10–20 minutes with water changes), but once absorbed it can’t be fully removed; choosing phosphate‑free products is the only way to avoid it entirely.
How to remove sodium tripolyphosphate from shrimp?
Rinse and soak the shrimp in cold water for 10–20 minutes (changing the water) to wash off some surface STPP, then drain and pat dry, but be aware that absorbed phosphate cannot be completely removed.
Is sodium tripolyphosphate safe?
Yes—when used within legal limits set by authorities like EFSA and FDA; EFSA has a group ADI for phosphates of 40 mg/kg body weight per day (as phosphorus), and people with kidney disease should limit intake of phosphate additives.
