Soy sauce is made from soybeans, defatted soybeans, black beans, etc. As raw materials, wheat or bran, and appropriate amount of water and salt. Soy sauce has a long history As early as the Zhou Dynasty, there was a record of making soy sauce. Soy sauce is evolved from soy sauce. The earliest soy sauce was marinated with fresh meat, which was close to the production process of fish sauce and was the royal condiment of ancient emperors.

After soy sauce spread from the imperial palace to the people, it was found that soy sauce made of soybeans tasted similar to soy sauce marinated with fresh meat, and it was cheaper, so it was widely circulated. In the early days, with the spread of Buddhism by monks, soy sauce was brought to all parts of the world, such as Japan, South Korea, Southeast Asia and so on, which had a wide influence.

The development history of soy sauce;

According to historical records, China was the first country in the world to make and eat soy sauce. As early as the Western Zhou Dynasty, there were "yeasts" fermented by meat and fish, and yeasts made by adding animal blood during brewing.

There is a phrase "I recommend it" in The Book of Songs, Daya Qi Hang; "Nine Zhengs in Zhou Li Celestial Officials" records the positions of "Ren Zhen" and "Ren Zhen"; The Biography of Historical Records and Huo Zhi mentioned that "most cities in Yi Tong ... have a thousand kinds of sauces". This shows that the brewing technology of maotai-flavor condiment has been popularized in the Zhou Dynasty, and the production technology has gradually become formal.

In the Qin and Han dynasties, there was a seasoning similar to soy sauce. In the "Four-person Moon Order" written by Cui Ai in the Eastern Han Dynasty, "... can make all kinds of sauces, meat sauces and clear sauces"; At the end of the Northern Wei Dynasty, Jia Sixie's Book of Qi Yao Min, Volume 8, also recorded the seasoning "clear bean paste". The word soy sauce began to appear in the Song Dynasty, which first appeared in the Northern Song Dynasty. Su Dongpo said in Shuo Shi Yun lue: "The gold note and the fan are wrongly written. Dip it in vinegar or soy sauce with a new pen or wipe it off with a wick."
