Beyond Extraction.
Preservation.

Traditional isolation methods use chemical extraction to strip protein from the bean. Our Membrane Filtration process retains the protein's native structure, enabling high solubility and clean taste.

Seed Genetics

Genetics First

Quality begins before the seed is planted. We select Non-GMO varieties specifically bred for Low Lipoxygenase content — traceable from the field to the factory. This biologically reduces the "beany" off-notes common in soy, prior to processing.

Aqueous Phase

Gentle Extraction

The soy flour is solubilized in water at a gentle, controlled pH. This keeps the protein intact — so it dissolves cleanly in your formulation.

The Core Technology

Membrane Filtration

Using industrial-scale Kanoria expertise, the liquid passes through precision membranes. These membranes act as molecular sieves, separating the protein from carbohydrates and minerals based on size, not chemical reaction.

Spray Drying

The purified protein concentrate is flash-dried. This rapid evaporation prevents heat damage, resulting in a free-flowing powder with excellent dispersibility.
