How to Start Soya Sauce Manufacturing Business

Soya sauce is one of the world’s oldest condiments and has been used in China for more than 2,500 years. Soya bean is a leguminous crop and is rich in proteins. Many value-added products are made from it like milk, paneer, cheese, and sauce.

Soya products are increasingly becoming popular, especially among health-conscious people. Soya sauce is used as a taste enhancer as it has a typical bitter-sour and sweet taste as well as flavour.

The appealing and unique colour, flavour, and fragrance of soy sauce are generated by the fusion of soybeans, wheat, and salt which are the main raw materials.

The taste is mainly from soybean proteins, and the fragrance is mainly from wheat starch, created as the microorganisms work on each ingredient. The characteristic colour comes from the combination of amino acids, obtained from proteins, and glucose, obtained from starch.
