Mannanase for Mannan-Rich Process Streams
For feed mills, coffee and guar processors, pulp mills and ingredient resellers: match a mannanase grade to your mannan-rich stream, then request a quote with product, quantity and destination.
Mannan-rich raw materials raise viscosity, slow filtration and trap extractable solids, and that costs throughput. Guar gum, green coffee beans, soybean meal, coconut and lignocellulosic fibre all carry mannans and related polysaccharides that strain pumps, filters and 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. Smaller polymers flow more easily and free valuable components for recovery. Our grade is specified at 10,000–50,000 U/g, with optimal pH 5.0–7.0 and 40°C–70°C, and is supplied as a light brown powder in 25 kg fiber drums (MOQ 25 kg).
In food and ingredient lines it lowers viscosity and supports cleaner clarification. In feed it targets the mannans that act as anti-nutritional factors. In guar processing it enables controlled viscosity tailoring, and in pulp and paper it supports brightness stability. The right dose depends on your substrate and process window, so plan a pilot trial under your actual pH and temperature before scale-up.

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.
