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.
How magnesium hydroxide works?
It works as a sparingly soluble base that releases hydroxide ions to neutralize acids and raise pH. In medicinal use it neutralizes gastric acid and, at higher doses, draws water into the intestines to promote bowel movements.
Is magnesium hydroxide safe?
Yes—at permitted food-use levels (E528) it is considered safe by regulators. High intakes can cause diarrhea, and people with kidney impairment should avoid excessive magnesium exposure.
Is magnesium hydroxide a strong base?
Chemically it’s a strong base, but its very low solubility means its aqueous solutions are only moderately alkaline compared with highly soluble bases like sodium hydroxide.
What is magnesium hydroxide used for?
In foods it’s used as an acidity regulator/alkalizing agent and processing aid to control pH. Outside foods it’s the active ingredient in some antacids (milk of magnesia) and osmotic laxatives.
What does magnesium hydroxide do?
In food products it neutralizes excess acidity and helps stabilize pH. Medically it relieves heartburn by neutralizing stomach acid and, at higher doses, promotes bowel movements by drawing water into the gut.
