What You Need to Know
Malic acid (C₄H₆O₅) from sumac lowers pH to 3.8-4.2, inhibiting bacterial growth while myofibrillar proteins unfold. Concurrently, sumac's anthocyanins (e.g., delphinidin-3-O-rutinoside) chelate iron ions to prevent lipid oxidation.
Creates tangy, shelf-stable meats without vinegar's harshness, while imparting a burgundy hue.
