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.
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.
