Hemicellulase

Hemicellulase is a complex of enzymes (xylanase, arabinanase, mannanase, galactanase) that hydrolyse the hemicellulose fraction of plant cell walls. In food processing it supports cell-wall breakdown, viscosity reduction and dough conditioning across a broad range of cereal and plant-matrix applications.

Off-white to light tan free-flowing powder, or amber liquid. Activity is standardised in Hemicellulase Units (HCU) or per supplier convention.

We supply food-grade Hemicellulase from manufacturers in China holding ISO 22000, Halal, Kosher and other certifications relevant to the product and production. Aspergillus niger, Trichoderma reesei and Bacillus species are the dominant source organisms.

Common market grades include 5,000 HCU/g standard bakery grade, 20,000 HCU/g for fruit and vegetable maceration, 100,000 HCU/g concentrated, and application-specific blends combining hemicellulase with pectinase and cellulase for total plant cell-wall breakdown.

Bulk and reduced-MOQ shipments. Batch-level COA covering activity, pH optimum, temperature optimum, side activities, heavy metals and microbiology.

Hemicellulase preparations have been used in commercial baking and brewing for decades, originally as crude side activities of pectinase and cellulase products. Modern strain engineering has produced dedicated hemicellulase preparations with defined ratios of xylanase, arabinanase and mannanase tuned to specific applications.

Industrial production is by submerged fermentation of Aspergillus niger, Trichoderma reesei and Bacillus strains. Hemicellulase is typically supplied as a blended preparation, with the activity ratio designed for the target substrate (wheat arabinoxylan, oat beta-glucan-cosmetic-grade-oat" class="underline" style="color: var(--sage-deep); text-decoration-color: var(--sage-deep);">beta-glucan, soy galactomannan) rather than a single substrate.

The enzyme complex is Generally Recognized as Safe by the U.S. FDA from approved source organisms, listed in the JECFA enzyme compendium, and approved as a processing aid in the EU.

Mechanistically, hemicellulose comprises a heterogeneous group of polysaccharides including arabinoxylan, glucomannan, galactoglucomannan and arabinogalactan. A complete hemicellulase preparation must therefore contain several backbone-cleaving and debranching activities to degrade the substrate efficiently. Single-activity preparations stall on branched substrates.

Strategic positioning in industrial food processing is broad: hemicellulase is a workhorse processing aid across baking, brewing, juice production, plant-protein isolation and prebiotic ingredient manufacture, and the activity ratio of a given preparation is often the differentiator between suppliers serving the same nominal application.

• Bread, bun and pastry dough conditioning; lifts volume and improves crumb texture in whole-grain and high-fibre breads
• Brewing of beer; reduces wort viscosity in high-adjunct mashes
• Fruit and vegetable juice extraction; supports cell-wall breakdown for yield and pigment release
• Plant-protein isolate manufacture; assists in cell-wall disruption and protein release
• Coffee and cocoa processing; mucilage degradation in wet processing
• Soybean and pulse-flour processing; reduces antinutrients and improves digestibility
• Animal feed for poultry and swine; releases nutrients from cereal cell walls
• Oligosaccharide prebiotic ingredient manufacture from hemicellulose substrates
