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 d alpha tocopherol?
It’s the natural stereoisomer of vitamin E (RRR‑α‑tocopherol, E307), typically derived from vegetable oils and used as an antioxidant and nutrient in foods.
Is d alpha tocopherol natural?
Yes—“d‑” indicates the naturally occurring RRR‑α‑tocopherol, usually sourced from plant oils; the synthetic form is labeled “dl‑” (all‑rac‑α‑tocopherol).
What is d-alpha tocopherol?
It’s the natural form of vitamin E (RRR‑α‑tocopherol, E307), the most biologically active isomer and commonly used as an antioxidant in foods.
Is d alpha tocopherol synthetic?
No; the “d‑” form is natural, while the synthetic version is the racemic “dl‑” (all‑rac) α‑tocopherol.
What is d alpha tocopherol acetate?
It’s the acetate ester of d‑α‑tocopherol used for improved stability in foods and supplements; the body converts it to active α‑tocopherol.
