Cellulase: High activity enzyme for digesting cellulose.

Applications: include: Agriculture, Food Processing, Paper, Pulp, Biofuels, Advanced Materials.

Scales: 100 mL laboratory packs through to multi-tonne industrial supply.

Properties: Our food-grade cellulase is an enzyme preparation derived from safe microbial sources, designed specifically for use in the food and beverage industry. It possesses hydrolytic activity against cellulose and other β-1,4-glucans, breaking down plant cell walls into simpler sugars without producing harmful by-products. Key properties include high specificity, stability under moderate temperatures and pH ranges suitable for food processing, and absence of toxic contaminants. Its primary use cases include enhancing juice extraction and clarity by breaking down fruit and vegetable cell walls, improving the texture and digestibility of plant-based foods, facilitating fermentation processes in brewing and wine production, and increasing nutritional bioavailability. Food-grade cellulase is valued for its ability to improve yield, consistency, and quality in plant-derived food products while maintaining safety for human consumption.
