Did you know?
Soy sauce has been produced in China for over 2500 years originally as a way to extend the salt supply — soybeans were fermented with salt creating a liquid that provided saltiness alongside flavor compounds. Japanese soy sauce (shoyu) was developed in the 17th century with a slightly different fermentation process using wheat alongside soybeans. The umami flavor in soy sauce comes from glutamates produced during fermentation. A single tablespoon of soy sauce contains approximately 900mg of sodium — more than the total daily sodium recommendation for most dog sizes.
