OatCraft Barista: A liquid protein glutaminase and neutral protease blend for developing oat milk protein functionality, texture and barista-style frothing. Protein glutaminase deamidates protein-bound glutamine residues, while controlled protease treatment modifies protein structure.
Application benefits
- Evaluate improved protein solubility in your oat base.
- Screen texture, foamability and foam stability.
- Assess performance in hot coffee and your final beverage formulation.

| Dose and treatment time | Optimised by screening your oat base and processing conditions. |
Process screening
Compare untreated controls, protein glutaminase alone and the combined blend. Measure soluble protein, bitterness, foam volume, drainage, coffee stability and heat stability. Excessive proteolysis may impair foam or flavour. These enzymes do not increase the total amount of protein.
How to evaluate
- Provide your oat material, solids content, complete formulation, process sequence and target beverage properties.
- Compare untreated controls with enzyme doses and treatment times at your intended pH and temperature.
- Measure the relevant process and beverage properties, then validate enzyme inactivation before packaging and confirm finished-product stability.
