Is Silken Tofu Gluten Free?

The Ingredient Breakdown

When determining if a processed food is safe for celiacs, we have to look beyond the main ingredient. In the case of silken tofu, the primary ingredient is Organic Soybeans. Soybeans are a legume and are naturally free of gluten. The safety of the product, however, relies on the coagulants and processing agents used to create that signature silky texture.

Let's look at the specific coagulants listed: Calcium Sulfate and Magnesium Chloride. Calcium Sulfate is simply food-grade gypsum, a mineral salt. Magnesium Chloride (often referred to as Nigari) is derived from seawater. Both of these are mineral-based coagulants that are pure and free of gluten. Unlike some starches or flavorings that can be derived from wheat, these minerals do not pose a cross-contamination risk.

The only potential risk in tofu production comes from flavorings or starches added to specific varieties (like teriyaki tofu or fried tofu). However, the plain silken tofu variety you are asking about relies solely on the soybean curd and water. Therefore, the ingredient profile is exceptionally clean and safe for a gluten-free lifestyle.

Nutritional Value

Silken tofu is a nutritional powerhouse, particularly for those on a gluten-free diet who may struggle to find high-quality plant-based proteins. A standard serving is very low in calories, typically ranging between 40 to 60 calories per 100 grams, making it an incredibly light option.

It is naturally low in sugar (usually less than 1g) and contains very little saturated fat. Because it is a complete protein containing all nine essential amino acids, it fits perfectly into a balanced diet aimed at muscle repair and energy maintenance without the heavy carbohydrate load of some other protein sources.
