Country of Consumption

Soy sauce is produced and consumed mostly in Asian countries. Owing to progress in world trade, soy sauce is now consumed almost worldwide. In 1978, soy sauce was exported from Hong Kong, the Korean Republic, Singapore, and Japan to a total of 97 countries (7,8).

Preparation

Different countries have different methods of preparing soy sauce. Even in Japan, there are five kinds of soy sauce: koikuchi, usukuchi, tamari, saishikomi, and shiro. The preparation of koikuchi soy sauce is outlined in Figure 1. The process includes (1) the treatment of raw materials, (2) koji making, (3) mash production and aging, (4) pressing, and (5) refining and pasteurization (8).

Treatment of Raw Materials. Cleaned soybeans or soybean meal is moistened (add 120-135% water) and cooked with steam under pressure. Wheat kernels are roasted at 170 to 180°C for several minutes and coarsely crushed into four or five pieces.

Koji Making. Equal parts of the resultant cooked soybeans or defatted soybean meal and roasted cracked wheat are mixed together and inoculated with 1 to 2% wt/wt of
