How Xylanase Works

Xylanase is a glycoside hydrolase that cleaves arabinoxylan — the most abundant hemicellulose in cereal crops — into soluble fragments and fermentable sugars.

Cuts Xylan Chains

Endo-xylanase cleaves internal xylosidic bonds, rapidly reducing arabinoxylan viscosity and releasing soluble oligomers for downstream processing or fermentation.

Redistributes Dough Water

In wheat flour, xylanase solubilizes water-binding arabinoxylans — transferring bound water to gluten and starch, improving dough extensibility and oven spring.

Breaks Down Cell Walls

In feed and biofuel, xylanase degrades plant cell wall polysaccharides, releasing nutrients and fermentable sugars otherwise locked inside hemicellulose.

Xylanase Applications by Industry

Xylanase is used wherever arabinoxylan or hemicellulose breakdown improves product quality, nutrient availability, or process yield.
빵 굽기

Increases loaf volume by 10–15%, improves crumb texture, and extends shelf life. Used in bread, rolls, tortillas, and other wheat-based products.

동물 사료

Reduces digesta viscosity in poultry and swine diets, improving feed conversion ratio and energy digestibility of wheat, rye, and barley-based feeds.

펄프 및 종이

Pre-bleaching kraft pulp with xylanase reduces chlorine chemical demand by up to 20%, cutting costs while improving pulp brightness and environmental profile.

Biofuel

Degrades hemicellulose in lignocellulosic biomass to release fermentable pentose sugars, improving ethanol yield in second-generation bioethanol production.

양조 및 음료

Reduces wort viscosity in wheat and rye beers, improving lautering speed and filtration. Also used in juice clarification and fruit wine production.

Xylanase Applications: Process Details, Dosage & Parameters

제빵 및 밀가루 처리

Baking | Arabinoxylan Modification & Dough Improvement

기능: Xylanase hydrolyzes arabinoxylans (pentosans) in wheat flour, releasing water-binding insoluble arabinoxylans and improving dough extensibility, water redistribution, and gluten network formation. This reduces mixing time, improves machinability, and produces a more open crumb structure — especially valuable for whole wheat and high-fiber formulations.

일반적인 복용량: 0.5–5 ppm based on flour weight; add directly to flour or at mixing stage; pH 5–6 in dough

응용 프로그램: Pan bread, whole wheat bread, baguette, high-fiber bread, industrial bread production, frozen dough.

동물 사료

Feed Manufacturing | Anti-Nutritional Factor (ANF) Reduction

기능: Arabinoxylans in wheat, rye, and barley-based diets increase intestinal viscosity, reducing nutrient absorption and worsening wet litter in poultry. Exogenous xylanase hydrolyzes these viscosity-causing arabinoxylans, improving nutrient digestibility and energy utilization. This reduces feed cost and improves growth performance.

일반적인 복용량: 500–2,000 U/g feed; thermostable grades required for pelleting (≥85°C); combine with beta-glucanase for maximum effect in barley diets

응용 프로그램: Wheat-based broiler and layer feeds, rye and barley diets, swine wheat-bran diets, aquafeed with plant proteins.

Pulp & Paper (Bleach Boosting)

Paper Manufacturing | Chlorine-Free Bleaching

기능: Xylanase removes xylan redeposited on cellulose fibers during kraft pulp cooking, which blocks bleaching chemical penetration. Enzymatic xylan removal (bio-bleaching pre-treatment) reduces chlorine dioxide demand in ECF bleaching by 15–25% and improves final pulp brightness. This is the most commercially significant industrial xylanase application.

일반적인 복용량: 0.05–0.2% w/w on pulp; 50–60°C; pH 7–9 (alkaline-stable xylanase required); 1–2 hours pre-bleach treatment

응용 프로그램: Kraft pulp ECF bleaching, TCF bleaching sequences, paper brightness improvement, bleach chemical cost reduction.

Biofuel & Biorefinery

Lignocellulosic Biomass | Hemicellulose Saccharification

기능: Xylan (hemicellulose) constitutes 15–30% of agricultural biomass and is the second most abundant polysaccharide after cellulose. Xylanase hydrolyzes xylan to xylose, which can be fermented to ethanol by pentose-fermenting yeasts or converted to xylitol. Xylanase also improves cellulose accessibility in biomass by removing hemicellulose sheathing.

일반적인 복용량: 0.05–0.2% w/w on dry biomass; 50–55°C; pH 5–6; 24–48 hours; combine with cellulase for maximum biomass conversion

응용 프로그램: 2G bioethanol from agricultural residues, xylose production, xylitol manufacturing, biorefinery co-product valorization.

Brewing & Beverages

Brewing | Wort Viscosity & Filtration Improvement

기능: Arabinoxylans contribute to wort viscosity and filtration resistance, particularly in wheat beer and barley-adjunct brewing. Xylanase hydrolysis reduces wort viscosity and improves lautering and filtration efficiency. Combined with beta-glucanase, xylanase is standard in adjunct brewing enzyme cocktails for high-viscosity grain bills.

일반적인 복용량: 0.01–0.05% w/w; add during mashing; 55–65°C; 30–60 minutes

응용 프로그램: Wheat beer, barley adjunct brewing, rye beer, oat stout processing, adjunct mashing optimization.

자주 묻는 질문

Xylanase is an enzyme that hydrolyzes xylan, a hemicellulose polymer composed of xylose units linked by beta-1,4 glycosidic bonds. In cereal grains, xylan exists primarily as arabinoxylan (AX) — xylan backbone substituted with arabinose. Both soluble and insoluble arabinoxylans have important functional effects in baking, brewing, and feed.
In bread dough (pH 5–5.5), fungal xylanase (pH optimum 4.5–6.0) performs well. For whole wheat applications where dough pH can be 5.5–6.0, xylanase with broader pH tolerance (4.5–7.0) is preferred. Thermostability to 60°C is required so the enzyme is active through most of the baking temperature rise before inactivation.
Typical dosage: 0.5–5 ppm based on flour weight. Start at 1 ppm and optimize by dough extensibility (alveograph Extensibility values) and crumb structure. Over-dosage causes sticky, slack dough by over-hydrolyzing water-binding arabinoxylans. Xylanase dosage is critical — 2–3× over-dose produces noticeably inferior dough.
Xylanase alone cannot fully replace bromate — it improves extensibility but does not strengthen dough oxidatively. However, xylanase combined with glucose oxidase (dough strengthener) and ascorbic acid provides comparable performance to bromate in many applications. Enzyme combinations are the industry-standard bromate replacement for industrial pan bread.
Minimum order is 1 kg for sample/trial. Commercial quantities in 25 kg drums. We stock baking-grade, feed-grade, and industrial-grade xylanase. Most orders ship within 3–5 business days.
Our food-grade xylanase is produced by GRAS-recognized organisms (Bacillus subtilis, Thermomyces lanuginosus, Aspergillus) and meets FCC specifications. Full documentation: CoA, TDS, GRAS reference, and Allergen Statement are available for each product.
Arabinoxylans in wheat, rye, and barley form viscous gels in the intestine, trapping nutrients and reducing absorption. Xylanase hydrolyzes these gels, freeing nutrients and lowering intestinal viscosity by 30–60%. This translates to measurable improvements in feed conversion ratio (FCR), daily weight gain (DWG), and litter dryness in poultry.
For kraft pulp bleach boosting: 5–20 IU/g dry pulp at 50–60°C, pH 7–9 (alkaline-stable xylanase required), 60–120 minutes. This reduces ECF bleach chemical (ClO₂) demand by 15–25%. Alkaline stability (active at pH 7–10) is the critical specification for pulp applications — most baking xylanases are acid-active and unsuitable.
Yes — xylanase, cellulase, and pectinase work synergistically for complete plant cell wall degradation. This combination is standard in juice processing, wine maceration, and biofuel applications. In baking, combining xylanase with cellulase and amylase provides comprehensive NSP modification.
Liquid xylanase: 4–15°C, 12 months. Dry/granular xylanase: ≤25°C, 18–24 months. Freeze-drying and microencapsulation improve stability for feed premix applications. Pelleting-stable xylanase (guaranteed activity after 85°C steam conditioning) is available for pelleted feed production.
