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 the refractive index of ktpp?
There isn’t a single published refractive index for solid pentapotassium triphosphate; food-grade specs don’t list it. For aqueous solutions, refractive index depends on concentration and temperature, so you’d need to measure nD under your specific conditions.
What is the refractive index of potassium triphosphate?
A fixed refractive index isn’t typically reported for the solid; it’s not a standard QC parameter for this additive. In solution, the refractive index increases with concentration and varies with temperature and wavelength, so measure it for your formulation.
What is the refractive index of potassium tripolyphosphate?
No standard single value is published for the solid; specifications for E451ii don’t include refractive index. For practical purposes, determine nD on your specific potassium tripolyphosphate solution at the required concentration and temperature.
