Traditional Uses of Soy Sauce for Food Preservation

Throughout history, soy sauce has been used extensively in traditional Asian cuisines for food preservation. It is commonly used to:

• Preserve fish and seafood: Soy sauce is a staple ingredient in many Asian fish and seafood dishes. Its saltiness and acidity help to inhibit spoilage and preserve the delicate flavors of these products.
• Preserve vegetables: Soy sauce can be used to pickle vegetables, creating a flavorful and long-lasting condiment. The salt and lactic acid in soy sauce help to prevent the growth of bacteria and preserve the vegetables’ texture.
