What auxiliary ingredients are added during the tofu‑making process?

2022年03月30日

Coagulants are indispensable auxiliary ingredients in the tofu‑making process. From ancient times to the present, whether in tofu production or in other soy‑based foods, the addition of coagulants—except in the case of glucono‑δ‑lactone tofu—is an essential step. Common tofu coagulants include glucono‑δ‑lactone, calcium sulfate, magnesium chloride, calcium chloride, and magnesium sulfate.

The addition of an antifoaming agent can reduce the formation of air bubbles in the finished tofu product; the impact of these bubbles on the product’s appearance is significant and cannot be overlooked.

Adding an appropriate amount of defoamer during the operation of the pulping machine plays a decisive role in eliminating bubbles in the liquid. Commonly used defoaming agents include glyceride-based, silicone resin–based, and emulsified silicone oil–based formulations. Typically, these are introduced into the soy milk prior to cooking to prevent foaming during the boiling process.
