Tofu packs more protein than many people realize, but the exact amount depends on its firmness and preparation. Extra-firm tofu leads the way with 10-12 grams per 3.5-ounce serving, while softer varieties like silken tofu drop to 3-4 grams. Since it’s made from condensed soy milk, the pressing process determines both texture and protein density. Some dismiss tofu as bland or rubbery, yet its versatility makes it an easy high-protein addition to stir-fries, scrambles, and smoothies. Beyond the numbers, how it’s cooked can change its nutritional impact.
What Is Tofu Made From?
Tofu is made from just a few simple ingredients, but the process turns them into something surprisingly versatile. Its primary soy bean source is soaked, ground, and boiled to create soy milk.
This milk is then curdled using a traditional coagulant, often nigari (magnesium chloride) or calcium sulfate, which separates the solids from the liquid. The resulting curds are pressed into blocks, forming tofu.
The simplicity of these steps belies the skill required to achieve the right texture. Since the soy bean source is packed with nutrients, the final product inherits much of its nutritional value.
The traditional coagulant not only shapes the tofu but also influences its firmness and taste. Comprehending these basics helps explain why tofu can range from silky soft to extra firm.
Different Types of Tofu and Their Protein Content
Tofu comes in various textures, each offering different protein levels per serving. Extra-firm tofu packs more protein due to its dense, compressed form, while soft tofu contains slightly less because of its higher water content.
Comprehending these differences helps choose the right type for protein needs.
