Hydrolyzed Protein and Manufacturing Methods
Three manufacturing methods: hon-jozo, kongo, and kongo-jozo
“Hon-jozo” does not necessarily mean “additive-free.” Ultimately it is only a soy sauce that does not contain “hydrolyzed protein,” and some hon-jozo contains various ingredients such as amino acids and sweeteners. Brewing methods and ingredients are indicated on the label and learning how to read labels can help you to buy the soy sauce of your choice.
