Soy sauce is a basic seasoning commonly used in cooking, and the market demand is stable and large. As a by-product of soy sauce production (waste residue and soy sauce residue), the output of the residue is also very huge. Soy sauce is basically made from soybean, wheat or flour. The oil content in soy sauce residue is as high as 21% to 28%, which is close to the oil content of rapeseed, and the crude protein content is above 11% or even as high as 31%. In addition, it is also rich in fiber, sugar, phospholipids and so on. There are also some soy sauces made from soybean meal and flour. The crude fat content of soy sauce residue is 74% to 86%, the crude protein content is 195% to 258%, and the reducing sugar content is 117% to 123%. In a word, in the fermentation process of soy sauce raw materials, except protein and starch in raw materials are partially utilized, other nutrients, such as oil, fiber and phospholipids, are mostly left in soy sauce residue, so soy sauce residue is rich in nutrients as animal feed. However, for a long time, people think that soy sauce residue is an industrial waste that disturbs people with strange smell. The reason is that the moisture content of soy sauce residue is relatively high, generally between 41% and 81%, which makes it easy to deteriorate and difficult to transport for a long time. However, enterprises that normally produce soy sauce produce a large amount of soy sauce waste residue every day, which must be treated immediately, otherwise, the environmental pollution is extremely serious, especially in summer, and if it is not treated in time, it will produce a strong pungent sour smell.
