Gypsum Powder

Description

Gypsum powder, also known as calcium sulfate, is a soft, chalky white substance that has been used in culinary applications for centuries. It possesses a fine, flour-like texture that is almost ethereal to the touch. A tasteless and odorless ingredient, gypsum powder is valued more for its functional properties than its flavor contribution. As an ingredient, it sets itself apart with its unique ability to coagulate soy milk into a smooth, silky tofu, a characteristic that distinguishes it from other coagulants.

Primary Uses

In the culinary world, gypsum powder plays a vital role in the making of tofu, a staple in Asian cuisine. It acts as a coagulant, transforming the soy milk into soft, silky blocks of tofu. It is also used in making traditional Chinese desserts, such as sweet, silky tofu pudding, also known as "Douhua". Apart from its culinary uses, gypsum powder has been used in traditional Chinese medicine for its calming properties and is believed to help in treating insomnia and hyperactivity.

History

The use of gypsum powder dates back to ancient China, where it was discovered as a natural byproduct of evaporated sea water. It was during the Han Dynasty (202 BC – 220 AD) that the Chinese began using gypsum as a coagulant in their tofu production, a technique that has been passed down through generations and still used today. There are even romantic tales of ancient tofu makers who would wait for the full moon to make their tofu, believing that the lunar energy would infuse the tofu with a special quality. Over time, the use of gypsum powder has spread across the globe, with its culinary and medicinal properties being recognized and utilized in various cultures.

Nutritional Information

Gypsum powder is a good source of calcium, an essential mineral for human health. It contributes to bone health, aids in proper muscle function, and helps in transmitting nerve impulses. It is also low in calories, making it a healthy addition to various dishes. When compared to other coagulants like nigari (magnesium chloride), gypsum powder is noted for its higher calcium content. However, it should be consumed in moderation, as excessive intake can lead to an imbalance in calcium and phosphorus in the body. As always, it's important to maintain a balanced diet and lifestyle for optimal health.
