There are many methods for denaturation of protein, such as acid, alkali, heavy metal salt and high temperature. Boiling is one of them, protein solidification is a kind of high temperature that leads to denaturation of protein, and the denaturation of acid can refer to the making of cheese. Specifically, you can search for "protein transsexuality" (I only make a general statement here, please search for details and get a professional answer)

On the other hand, the degeneration of protein will destroy the spatial structure of protein, making the mobility worse and easier to condense. Boiling at high temperature is protein denaturation, which produces colloid and carries out pre-treatment. Biological level

Brine is an aqueous solution of crystalline magnesium chloride [[[MGC L2·6H2O]]], which belongs to electrolyte solution. It can neutralize the charge of ions adsorbed on the surface of colloidal particles, and make protein molecules reunite to obtain tofu. This paragraph is a quoted copy, because I am not a chemistry major, so I am afraid of misleading everyone.

After these two steps, tofu can be initially formed.
