Popular questions
Is citric acid bad for you?
At typical food levels, citric acid (E330) is considered safe by major regulators (GRAS; EFSA/JECFA). Concentrated or frequent acidic exposure can irritate the mouth/stomach or contribute to tooth enamel erosion.
Where does the citric acid cycle occur?
In eukaryotic cells it occurs in the mitochondrial matrix; in bacteria it occurs in the cytosol.
What does citric acid do to your body?
It is a normal intermediate in energy metabolism and is readily metabolized to carbon dioxide and water. Citrate can bind minerals, which may enhance absorption of some and help prevent certain kidney stones by increasing urinary citrate.
Where does citric acid come from?
It occurs naturally in citrus fruits, but most food-grade citric acid is produced by fermenting sugars (e.g., from corn, beet, or cane) with Aspergillus niger.
How is citric acid made?
Industrially, sugars are fermented with Aspergillus niger to produce citric acid, then it is recovered and purified—often by precipitating calcium citrate and converting it back with sulfuric acid or via ion-exchange/crystallization.
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.
