Soya Sauce

You’re probably already familiar with soya sauce. This salty, umami-packed flavor bomb of a condiment has broken beyond the bounds of Asian cuisine to add an X factor of savoriness to everything from barbecue sauce to chili.

Our soya sauce

‌Soy sauce is a popular food used both as a cooking ingredient and a condiment. 

The history of soy sauce goes back over 2,000 years in China. It was developed to help keep food from spoiling and add flavor to it, as salt was expensive at the time. It was introduced to Japan in the 7th century and later to Korea and Southeast Asia. It is now popular in many other parts of the world.  

What is Soy Sauce?

‌Soy sauce is known as shoyu and soya sauce. It’s made with soybeans, wheat, salt, and a fermenting agent.

The traditional brewing method to make soy sauce involves soaking soybeans in water for several hours and steaming them. Wheat is then roasted, ground into flour, and mixed into the steamed soybeans. Fungal spores, usually Aspergillus oryzaeA. sojae, and A. tamarii, are added in and left for 3 days.  

The next step is fermentation, where a brine solution is added. This may be left to ferment for from 1 month up to 4 years. For some premium soy sauces such as double-fermented soy sauce (saishikomi-shoyu), a raw soy sauce mix is added. After fermentation, the mixture is pressed to filter the solids, heated to remove molds and yeasts (pasteurized), and packed. 

The acid hydrolysis method is much faster, taking just a few days. This uses soybeans without the oil, wheat gluten, and hydrochloric acid. The mixture is heated for 20 to 35 hours to break down the proteins. 

Some soy sauces are a mixture of both traditional brewing and acid hydrolysis, which makes them cheaper but less tasty. A longer brewing time means better flavor.
