Tofu is more than just a food—it's a symbol of purity, nutrition, and tradition. At the heart of making high-quality tofu lies one key ingredient: the coagulant. While gypsum (calcium sulfate) and GDL (glucono delta-lactone) are commonly used, one coagulant continues to lead the way in both performance and tradition: magnesium chloride, also known as nigari.
At Shandong Runfu Ca Mg Chemical Technology Co., Ltd., we specialize in supplying high-purity magnesium chloride, trusted by food manufacturers and tofu producers worldwide.
Magnesium chloride is a naturally occurring salt often extracted from seawater. It has been used for centuries in traditional tofu-

making across East Asia, and for good reason:
Magnesium chloride produces tofu with a firm, elastic texture—ideal for slicing, stir-frying, or grilling. It’s the go-to choice for traditional hand-crafted tofu that holds its shape and delivers a satisfying chew.
Unlike other coagulants that may mute the natural flavor of soy, magnesium chloride preserves and enhances the authentic taste of the soybeans. This makes for a richer, more aromatic tofu.
Magnesium chloride acts quickly to coagulate soy milk, making it efficient for commercial tofu production. Its reliable performance ensures consistent quality and yield.
Our food-grade magnesium chloride is free from additives and contaminants, meeting international standards for food safety and purity.
While gypsum offers added calcium and GDL creates ultra-soft tofu, neither can match magnesium chloride when it comes to producing traditional, firm tofu with bold flavor and satisfying texture. It’s the coagulant of choice for professionals who want authentic results.
