Mannanase: High activity mannanase for digesting mannan.
Applications: include: Agriculture, Food Processing, Paper, Pulp, Biofuels, Cleaning, Advanced Materials.
Properties: Our food-grade mannanase is an enzyme derived from safe microbial sources that specifically hydrolyses mannans and galactomannans, which are complex polysaccharides found in plant cell walls. Key properties of food-grade mannanase include high substrate specificity, stability under moderate temperatures and pH levels suitable for food processing, and absence of toxic or allergenic contaminants, making it safe for human consumption. Its primary applications in the food industry include improving the viscosity and clarity of fruit juices, enhancing extraction of oils and bioactive compounds, reducing anti-nutritional effects of mannans in legume-based foods, aiding in coffee and tea processing, and improving texture and digestibility in baked goods and plant-based products. By breaking down mannans efficiently, food-grade mannanase helps increase yield, optimize product quality, and enhance nutritional availability in a variety of plant-derived foods.
