  5. 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.
