Natural calcium sulfate (gypsum) and magnesium chloride (nigari) are the most common tofu coagulants used. They have been used for hundreds years in Japan and China. Nigari is composed mainly of magnesium chloride, but also contains other minerals found in seawater, with the exception of sodium chloride (sea salt). Gypsum is a naturally occurring calcium sulfate. Click here for instructions on how to make tofu. You can make tofu manually or with our Automatic Soy Milk Maker.

8 ounces of nigari can make about 120 pounds of tofu, depending on firmness. 16 ounces of gypsum can make about 120 pounds of tofu. 

Please note that both calcium sulfate and magnesium chloride are also available in other grades for industrial use. Ours are food grade, specifically for making tofu.

What type to buy, gypsum or nigari? It really depends on you. Nigari is believed to make better tasting tofu, but gypsum contains calcium. Why not try both and see which type you prefer?

We sell nigari in 16 ounce bags and gypsum in 12 ounce bags.  If you order with the SoyaJoy Soy Milk Maker, shipping is free.
