Does your papaya enzyme meat tenderizer have 35 TU/mg activity?

A real customer question, curated into a useful guide for cooking, product use, and finding just the right thing.

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.
