Our Papain (natural Papaya-based enzymatic meat tenderizer) is standardized at 2,000 USP/mg, not 35 TU/mg. USP (United States Pharmacopeia units) and TU (Tyrosine Units) are two different systems for measuring enzyme activity, so the numbers aren't directly comparable — there's no simple conversion between them.
- **Papain (natural Papaya-based enzymatic meat tenderizer)**: pure papaya-derived enzyme, standardized at 2,000 USP/mg.
- Prefer a different documented potency standard? Our **Bromelain Powder 150gdu (Ananas comosus)** is a plant-based tenderizing enzyme rated at 150 GDU, another well-established activity measure worth comparing against your recipe's requirements.
