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 monopotassium phosphate used for?
In foods (E340i) it’s used as an acidity regulator/buffer, emulsifying and stabilizing salt, humectant and thickener, and as a source of potassium and phosphate.
Is monopotassium phosphate an electrolyte?
Yes—it's a salt that dissociates into potassium (K+) and phosphate ions in water, so it acts as an electrolyte and is used to adjust mineral content and pH.
What does monopotassium phosphate do to the body?
It provides potassium and phosphate: potassium supports nerve and muscle function and fluid balance, while phosphate supports energy metabolism (ATP) and bone; normal food levels are safe, but people with kidney disease should avoid excessive intake.
What is potassium phosphate monobasic?
It’s another name for monopotassium phosphate (KH2PO4), the monobasic salt of phosphoric acid approved as food additive E340i.
Cannabis when to foliar feed with monopotassium phosphate?
Growers typically apply it as a dilute foliar spray in early bloom or to correct P/K deficiencies, at lights-off or cooler times; avoid spraying buds or late flower to reduce residue and mold risk.
