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.

What foods contain tbhq?
