Popular questions
Is disodium phosphate bad for you?
Generally no—E339(ii) is an approved additive used at low levels; however, it contributes sodium and phosphate, so people with kidney disease or on phosphate‑restricted diets should limit it.
What is disodium phosphate in food?
It's the sodium salt Na2HPO4 (E339(ii)) used as an emulsifier, acidity regulator/buffer, stabilizer, sequestrant, humectant, and thickener.
What is disodium phosphate used for?
It emulsifies processed cheese, controls acidity, improves texture and moisture retention in dairy and meat products, and binds metal ions that can affect flavor and color.
Is disodium phosphate safe?
Yes—it's permitted by regulators (e.g., FDA GRAS; EU E339) and considered safe at typical food levels, though very high phosphate intakes are discouraged, especially for people with kidney problems.
What does disodium phosphate do?
It keeps mixtures smooth and stable, maintains pH, binds minerals to protect quality, and can help foods retain moisture and thickness.
Is monosodium phosphate bad for you?
At permitted food levels E339(i) is generally considered safe; EFSA has set a group ADI for phosphates of 40 mg/kg body weight per day (as phosphorus). Very high intakes may be a concern for people with kidney disease or those needing to limit sodium/phosphate.
Explain why an aqueous solution of monosodium phosphate would be ineffective?
As a buffer near neutral pH, a solution of only monosodium phosphate (NaH2PO4) is too acidic and lacks its conjugate base; effective phosphate buffering requires a mixture of mono- and disodium phosphate (H2PO4−/HPO42−) at the target pH.
How does monosodium phosphate make gas?
In leavening systems it acts as an acid that reacts with baking soda (sodium bicarbonate) to release carbon dioxide gas, which aerates doughs and batters; by itself it does not generate gas.
How to change the ph of protein solution without precipitation using monobasic sodium phosphate?
Use a phosphate buffer pair: slowly titrate with small amounts of monobasic (NaH2PO4) and disodium phosphate (Na2HPO4) to reach the target pH, staying away from the protein’s isoelectric point and keeping the buffer modest (e.g., ~10–50 mM). Make adjustments gradually with constant stirring and temperature, maintaining ionic strength (a little NaCl can help) to minimize precipitation.
How to clean up monosodium phosphate?
For small spills, avoid dust, sweep or scoop up the solid and rinse the area with water; for solutions, absorb with inert material and dispose according to local regulations. Because it’s highly water‑soluble and nutrient-rich, avoid flushing large amounts to drains or waterways.
