Protein Glutaminase Powder

Protein-L-glutamine amidohydrolase catalyzes the selective deamidation of protein-bound L-glutamine residues, converting neutral glutaminyl side chains into negatively charged glutamyl groups. This increased negative charge density induces electrostatic repulsion within the protein matrix, preventing flocculation and significantly improving solubility in aqueous systems. Unlike harsh chemical deamidation, this enzymatic pathway preserves the polypeptide backbone and essential amino acids, maintaining nutritional value. The enzyme's high specificity restricts deamidation to targeted sites without peptide cleavage, avoiding the formation of bitter hydrophobic peptides. This selective modification enables food scientists to formulate stable plant-based beverages, meat alternatives, and dairy-like emulsions with improved texture and organoleptic properties.

Applications

Plant-Based Food Formulations

• Oat and soy milk systems: prevents phase separation through increased negative charge density
• Meat alternatives: improves gelling and moisture retention by modifying protein conformation
• Grain protein processing: reduces viscosity during concentration steps

Dairy and Dairy-Alternative Products

• Yogurt: increases gel strength and reduces syneresis through cross-linking
• Cheese-like formulations: improves fat dispersion and meltability via modified protein amphiphilicity
• Concentrated milk proteins: prevents thermal gelation during sterilization

Bakery and Cereal Processing

• Dough systems: adjusts extensibility and handling through targeted deamidation of wheat gluten
• Egg-free bakery formulations: enhances foaming and foam stability via improved protein adsorption at air-water interfaces

Packaging and Storage

The powder is packed in sealed, multi-layer aluminum foil bags under aseptic conditions to prevent moisture absorption and microbial contamination. Store in a cool, dry environment below 15°C to preserve enzyme activity. HDPE drums provide additional protection against mechanical stress. Custom packaging sizes and vacuum-sealed configurations are available upon request.
