Popular questions
Is ascorbyl palmitate safe?
Yes—it's approved as a food antioxidant in the EU, U.S., Canada, Australia, and New Zealand and is considered safe at permitted levels. The body breaks it down into vitamin C (ascorbic acid) and palmitic acid; high supplemental intakes may occasionally cause mild stomach upset.
What is ascorbyl palmitate in supplements?
A fat‑soluble form of vitamin C used either as the active vitamin C or to protect oils and softgels from oxidation. It’s hydrolyzed to ascorbic acid and palmitic acid, so its vitamin C activity is similar to regular vitamin C but it’s favored for oil‑based formulations.
What is ascorbyl palmitate made from?
It’s the ester of L‑ascorbic acid (vitamin C) and palmitic acid, typically derived from palm oil or other fats. It’s produced by chemical or enzymatic esterification; sources can be plant, animal, microbiological, or synthetic.
Ascorbyl palmitate what is it?
Ascorbyl palmitate (E304i) is a fat‑soluble ester of vitamin C used as an antioxidant in foods, especially those rich in fats. It helps slow oxidation and rancidity and can also act as a source of vitamin C.
What is ascorbyl palmitate used for?
Primarily as an antioxidant (E304) to prevent rancidity and preserve flavor and color in foods like oils, margarines, snacks, and baked goods. It’s also used in supplements to stabilize oil‑based ingredients and sometimes as a vitamin C source.
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.
