What You Need to Know
Yogurt lowers the meat pH to 4.5–5.5, activating lactate‑dependent proteases that cleave myofibrillar proteins. The acidic environment also denatures surface proteins, improving water retention and juiciness. The combination of acid, enzymes, and cold temperature yields a tender yet firm texture.
