Popular questions
What is bht in food?
BHT (butylated hydroxytoluene, E321) is a synthetic antioxidant added in small amounts to keep fats and oils from oxidizing, helping foods stay fresh and resist rancidity.
Is bht bad for you?
Major regulators (FDA, EFSA, JECFA) consider BHT safe at permitted levels, with an acceptable daily intake around 0.25–0.3 mg/kg body weight/day. High doses in animal studies have caused liver/thyroid effects, but evidence of harm at normal food-use levels in humans is limited.
What is bht in cereal?
It’s an antioxidant preservative used to keep the cereal’s fats from going rancid; in some products it’s applied to the packaging liner rather than the cereal itself to help preserve freshness.
What is bha and bht?
BHA (E320, butylated hydroxyanisole) and BHT (E321, butylated hydroxytoluene) are synthetic antioxidants used to slow the oxidation of fats and oils in foods, helping preserve flavor and shelf life.
What is bht and why you should avoid it?
BHT is a synthetic antioxidant used to prevent rancidity and preserve freshness. It’s considered safe at regulated levels, but some people choose to avoid it due to its synthetic origin or concerns from high-dose animal studies.
Can dogs have rosemary extract?
Yes—small amounts of rosemary extract (E392) used as a food preservative are generally safe for dogs; avoid giving concentrated essential oils and stop if stomach upset occurs.
Can dogs eat rosemary extract?
It’s commonly used in dog foods as a natural antioxidant and is considered safe at low levels, but consult your vet if your dog is prone to seizures or is pregnant/lactating.
Can cats have rosemary extract?
In the tiny amounts used as a preservative, rosemary extract is generally considered safe for cats; do not use rosemary essential oil, as cats are very sensitive to concentrated oils.
How to extract rosemary oil?
Rosemary essential oil is typically obtained by steam distillation of the herb, producing a highly concentrated oil that is not the same as E392 and isn’t intended for ingestion without expert guidance.
How to make rosemary extract?
Commercial E392 is made by extracting rosemary with food‑grade solvents (e.g., ethanol), then purifying and standardizing carnosic acid/carnosol levels; at home you can approximate it by steeping dried rosemary in high‑proof food‑grade alcohol and filtering, though it won’t be standardized.
