Green Hemp Tofu of Pueblo: A Soy-Free, Protein-Rich, and Tasty Alternative

A Healthy and Nutritious Plant-Based Alternative to Traditional Sources of Protein

At a Glance

Researchers at Colorado State University have developed a new hemp-based tofu, instead of traditional soybeans. Hemp seeds have high nutritional value and researchers at CSU Pueblo were able to optimize a protocol to process and create a new, nutritious type of tofu.

Hemp tofu offers an allergy-friendly alternative to soy-based products like tofu and tempeh, while also providing added nutritional benefits and a pleasant nutty flavor. Moreover, the green hemp tofu developed here has been supplemented with other vegetables, providing an extensive range of texture, flavor profiles, and added health benefits.


Hemp seeds have been utilized in the human diet for thousands of years. This green hemp tofu super-food has enormous nutritional value including essential amino acids, fatty acids, as well as omega-3s, vitamin E, and iron. Moreover, hemp tofu has the potential to be an alternative high protein source for individuals with an allergy to soy products. Despite the nutrient benefits, hemp tofu has yet to be well-received in the market due to its unique flavor profile and texture.

Consequently, researchers at Colorado State University Pueblo have endeavored to overcome these previous shortcomings through the optimization of processing and the development of a standard procedure to create a delicious and firm tofu from hemp seeds.
