Mannanase for Mannan-Rich Process Streams
Addressing mannan-rich substrates across industrial applications, mannanase enables higher yield, reduced viscosity, and improved downstream efficiency.
Mannan-rich raw materials often increase viscosity, slow filtration, and trap extractable solids, limiting production efficiency. Whether processing guar gum, green coffee beans, soybean meal, coconut, or lignocellulosic fibre, excess mannans and related polysaccharides create costly bottlenecks and strain downstream equipment. Mannanase (EC 3.2.1.78), sourced from Bacillus lentus and Trichoderma reesei, hydrolyses the β-1,4-mannosidic bonds in galactomannans and glucomannans. This reduces polymer size, improves flow properties, and frees valuable components for recovery. With an activity range of 10,000–50,000 U/g, optimal pH 5.0–7.0, and operating temperatures 40°C–70°C, it is compatible with diverse processing windows. In food and ingredient applications, mannanase lowers viscosity and supports cleaner clarification. In feed, it combats anti-nutritional factors, improving digestibility and conversion ratios. In guar processing, it enables controlled viscosity tailoring. Pulp and paper operations benefit from enhanced brightness stability and reduced bleaching chemical demand. Controlled dosing—commonly 50–300 g/t for feed and 0.05–0.30% on dry substrate for food and ingredient systems—balances performance with cost. Initial pilot trials, under your actual pH and temperature conditions, allow optimisation based on yield, viscosity reduction, or nutrient availability targets. For procurement and technical teams, integrating mannanase offers a direct route to better throughput, product consistency, and downstream reliability without major process redesigns.
Coffee Extraction and Filtration
In coffee wet processing, galactomannans can raise viscosity and slow filtration. Mannanase hydrolyses these polysaccharides, enhancing liquor flow and extraction efficiency. Trials are usually run at pH 5.0–6.5 and 45°C–60°C, with dosage adapted to bean quality and solids loading. The outcome is improved flavour compound recovery and less pressure on downstream separation equipment.
Poultry Feed Performance
Soybean meal and similar plant proteins contain beta-mannans that act as anti-nutritional factors. Mannanase breaks these structures down, reducing gut viscosity and improving feed conversion ratio. Feed mills often evaluate 50–300 g/t depending on ingredient profile and pelleting conditions. Benefits include better nutrient availability, more predictable performance, and improved feed economics.
Guar Gum Modification
Guar processing requires precise viscosity control for food, cosmetic, or oilfield applications. Mannanase enables targeted depolymerisation of guar galactomannan, letting producers tailor functional performance without overprocessing. Trials are commonly run at pH 5.0–7.0 and 45°C–65°C, supporting grade standardisation and tighter specification compliance.
Pulp, Paper, and Fibre Treatment
In kraft pulp and fibre processing, mannan removal supports brightness stability and cleaner downstream performance. Mannanase reduces residual mannans that interfere with bleaching efficiency. Mills typically screen dosage under alkaline-to-neutral compatible conditions, aligning stage integration with optimal activity. This helps improve line efficiency, reduce variability, and maintain product quality.

Frequently Asked Questions
What is mannanase used for in industrial processing?
Mannanase hydrolyses mannans and galactomannans in food, feed, fibre, and ingredient processing. By reducing polymer size, it lowers viscosity, improves extraction, and supports more efficient separation. In feed, it reduces anti-nutritional effects from plant ingredients. In guar and pulp systems, it enables controlled modifications in product performance and quality. Applications depend on substrate, target hydrolysis, and process conditions.
How do I choose the right mannanase dosage?
Dosage depends on raw material, solids content, residence time, and desired outcomes. Feed applications often start at 50–300 g/t, while food and ingredient systems trial 0.05–0.30% on dry substrate. High-solids or more resistant mannans may require staged optimisation. Pilot trials under your process pH and temperature help refine dosing based on viscosity reduction, yield improvement, or conversion ratios.
Is this mannanase suitable for food and feed production?
Yes. It is available in grades suitable for both food and feed use, with certifications including ISO 9001, HALAL, Feed Grade, and Food Grade. Supplied as a light brown powder, it integrates into batch or continuous processes. Technical validation should be conducted for your specific system, especially where heat, shear, or regulatory parameters affect enzyme performance. Confirm specifications before full-scale production.
What process conditions support best activity?
Optimal performance is typically achieved at pH 5.0–7.0 and 40°C–70°C, though exact settings depend on substrate and process design. Food and extraction systems often run mid-range conditions, while some feed or fibre steps use higher temperatures with shorter residence times. Matching enzyme activity to your process window is more important than aiming for a single ideal point.
Can mannanase help with mannana-related viscosity problems?
Yes. When mannans build up in the process stream, viscosity increases and can hinder mixing, pumping, and filtration. Mannanase reduces polymer size, improving flow and throughput. For operations facing mannana-related bottlenecks, it is often a practical first-line solution before considering major process changes.
