What You Need to Know
The acidic vinegar denatures myofibrillar proteins while the salt from soy sauce promotes collagen hydrolysis to gelatin, creating a silky mouthfeel. Sulfur compounds from garlic and aromatic terpenes from bay leaves add complexity, and umami nucleotides enhance flavor perception. The low water activity also inhibits microbial growth, extending shelf life.
