Popular questions
Is sodium bisulfite bad for you?
At approved food-use levels, sodium bisulfite (E222) is considered safe; regulators set a group ADI of 0–0.7 mg/kg body weight expressed as SO2. However, sulfite‑sensitive people—especially some asthmatics—may experience reactions like wheezing, hives, or headaches and should avoid it.
What is sodium bisulfite used for?
It’s an antioxidant and preservative that prevents browning and oxidation and helps control microbes, commonly used in products like wines, dried fruits, shrimp, and cut potatoes.
What is sodium bisulfite in food?
It’s a sulfiting agent (E222) that releases sulfur dioxide to protect color and flavor and extend shelf life; it must be declared on labels when present above about 10 ppm (as SO2).
How much sodium bisulfite to neutralize chlorine?
Approximately 1.5 mg of sodium bisulfite (NaHSO3) is needed per 1 mg of free chlorine (as Cl2) per liter, stoichiometrically. In practice use a slight excess and confirm with a chlorine test; the reaction releases heat and SO2, so handle carefully.
Is sodium bisulfite gluten free?
Yes—sodium bisulfite is a synthetic mineral salt and contains no gluten; any gluten risk would come from other ingredients, not the additive itself.
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.
