meat tenderizer
A seasoning powder, usually containing salt plus a proteolytic enzyme such as papain, sprinkled on meat before cooking to break down tough surface fibers and speed tenderizing. It works on the surface layer rather than all the way through, so it helps a tough cut but doesn't replace choosing the right cut or cooking method.
Buying guidance
Check the ingredient list -- concentration and added salt vary by brand, and some blends are mostly salt with only a little active enzyme. Because it already contains salt, hold back on separate seasoning until you've tasted the finished dish.
Substitutions
- Marinade with papaya, pineapple, or kiwi -- natural enzymes do the same job, but watch the time closely; left too long the surface turns mushy.
- Mechanical pounding with a meat mallet -- no enzymes involved, so no risk of oversoftening, just physical fiber breakdown.
- A slower cooking method instead, such as braising or long roasting -- tenderizes tough cuts without any powder.
Tips & common mistakes
Leaving it on meat well beyond the time the label suggests doesn't just tenderize further -- the enzyme keeps breaking down protein past the point of pleasant texture and turns the surface mushy or mealy, so it's not something to apply and forget overnight.
Storage
Keep the dry powder sealed and away from moisture like any spice blend; its enzyme component can lose potency over time even if the product still looks and smells fine, so if it stops noticeably tenderizing, replace it rather than trusting the date alone.
