Popular questions
What is adenosine triphosphate?
Adenosine triphosphate (ATP) is a biological energy-carrying molecule and not the food additive E451; E451 refers to inorganic triphosphates (e.g., sodium tripolyphosphate) used in foods as sequestrants and stabilisers.
What is sodium triphosphate?
Sodium triphosphate (sodium tripolyphosphate, STPP; Na5P3O10) is the E451 additive—an inorganic triphosphate used to bind metal ions, retain moisture, and improve texture in foods.
Which of the following statements about inositol triphosphate is false?
It’s false to claim that inositol triphosphate is E451 or used as a food additive; E451 is inorganic tripolyphosphate salts (e.g., STPP), not the cellular messenger IP3.
What are nucleoside triphosphates?
Nucleoside triphosphates (e.g., ATP, GTP) are biological building blocks of nucleic acids and energy carriers, not the E451 additive; E451 comprises inorganic triphosphate salts used as sequestrants and stabilisers in foods.
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.
