Problems solved by technology

For example, the brine used in the brine point system is calcium chloride and magnesium chloride. There are a lot of free salts in the production process, which will produce a heavy smell. Those who are allergic to the smell should not approach the production workshop, and use this method. The produced tofu needs to be boiled in boiling water before it can be eaten. Disposal of salt substances with water in the environment will pollute the environment. In addition, because tofu contains calcium and magnesium ions, it is not suitable for patients with stones. When the content of calcium and magnesium ions is high prone to gallstones
