Developed for Tofu Functionality

Tofu quality starts at the seed. At PURIS, we’ve spent over 40 years developing non-GMO food-grade soybean genetics specifically for food applications.

Through our proprietary breeding program, we select and refine soybean varieties based on their performance during tofu production, not just on paper. Every PURIS tofu variety is optimized for protein functionality during coagulation, gel strength and curd formation, consistent yield and water holding, and texture and firmness control across processing conditions.

Our proprietary process includes:

Breeding and genetic selection
In-House Breeding
Proprietary genetic selection of non-GMO food-grade soybean lines.
Field trials and agronomic validation
Field Validation
Multi-year field trials and agronomic validation across regions.
Soy food application testing
Application Testing
Soy food production and application testing as part of variety screening.
Third-party analytical testing
Analytical Testing
Third-party analysis of composition and functionality.
Protein composition profiling
Protein Profiling
Evaluation of structure-driving fractions, including the 11S:7S ratio.
Certified Checkmark Icon
Pilot Tofu Trials
Pilot-scale production assessing gel formation, curd structure, and firmness.
Tofu cubes, whole soybeans, and soy milk
