Do soy sauce and rice make a protein?

Soy sauce and rice together do not form a complete protein, but they can complement each other nutritionally. Soy sauce is made from fermented soybeans, which contain some protein, while rice provides carbohydrates. Combining the two can enhance the overall amino acid profile, but for a complete protein, it is best to include other sources like legumes or meat. Therefore, while they contribute to protein intake, they are not sufficient alone to provide all essential amino acids.
