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.
What is tbhq in food?
TBHQ (E319) is a synthetic antioxidant added to fats and oils to slow oxidation, helping prevent rancidity, off-flavors, and color loss in foods.
Is tbhq bad for you?
At the low levels allowed in foods, it’s considered safe by regulators; adverse effects have been observed only at much higher doses in animal studies, with an ADI of 0–0.7 mg/kg body weight/day.
Tbhq what is it?
TBHQ (tert‑butylhydroquinone) is a phenolic antioxidant preservative used to stabilize fats and oils in processed foods.
What foods contain tbhq?
It’s commonly used in vegetable oils and fat-rich processed foods such as snacks (chips, crackers), instant noodles, microwave popcorn, baked goods, and some fast‑food frying oils.
How much tbhq is harmful?
The acceptable daily intake is 0–0.7 mg per kg body weight per day (about 50 mg/day for a 70‑kg adult); regulations typically cap TBHQ at 200 mg/kg (0.02%) of the fat or oil, and adverse effects are linked to doses far above these levels.
