Import Beta-Dextranase — Buy in wholesale FOB from Supplier in China

Beta-dextranase from Anke Bioengineering Co., Ltd. is a beta-1,3-1,4-glucosidase enzyme preparation produced by deep liquid fermentation of Bacillus licheniformis. The enzyme targets the 1,3 and 1,4 glycosidic linkages in beta-glydans, generating oligosaccharides of 3-5 units and glucose as hydrolysis products. This endo-acting enzyme is supplied as a tawny powder with declared activities of 1000 U/g or 2000 U/g, though industrial grades from 1000 to 5000 U/g are typical for this commodity class. The product operates optimally at 50-55 degrees Celsius and pH 6.0-6.5, with a functional range of 30-60 degrees Celsius and pH 4.8-7.5.

The production strain, Bacillus licheniformis, is a well-characterised industrial microbe for extracellular enzyme secretion, yielding a stable preparation with moisture content at or below 8.0 percent. The tawny colour reflects the presence of residual fermentation solids and stabilising carriers standard for powdered enzyme formulations. Activity units follow the international convention: one unit equals the enzyme quantity that hydrolyses 1 percent barley beta-glycan to release 1 micromole of glucose per minute at 40 degrees Celsius and pH 6.0. Buyers should note that feed-industry units differ by a factor of 1000, so 1000 U/g on the international scale equates to 1000000 U/g in domestic Chinese feed nomenclature. Storage below 10 degrees Celsius preserves full activity for 12 months; at 25 degrees Celsius, 95 percent activity is retained for 6 months.

Primary applications span sugar refining (preventing dextran-induced crystallisation issues), brewing (reducing wort viscosity, improving filtration and malt dissolution, preventing haze), baking (modifying dough rheology from cereal endosperm beta-glycans), and animal feed (enhancing nutrient availability). Standard dosing in brewing is 100-300 g per tonne of malt during mashing, or 4-10 g per tonne of wort added to the fermentation vessel. The product is manufactured in Jinan, Shandong Province, and exported globally from China. Buyers should confirm activity assay method, certificate of analysis for each lot, and cold-chain integrity for bulk shipments.

Anke Bioengineering Co., Ltd. is located at 11 Kaiyuan Road, Licheng Area, Jinan, 250101, Shandong Province, China. The supplier holds a harbor trust tier on the platform, with a response rate of 0.00 percent and zero recorded average response hours. No verification of manufacturing certifications, ISO status, or export licences is stated in the available profile. The company operates in the enzyme manufacturing sector, specifically producing fermentation-derived industrial enzymes for food and feed applications from a facility in Shandong, a province with established biotechnology infrastructure.

The listing provides operational standard reference Q/FSMW001-2003, suggesting internal quality management, though buyers should request current GMP compliance, food-grade enzyme registration status, and halal or kosher certification if required for their market. No information on production capacity, batch consistency protocols, or third-party audit history is disclosed. The supplier's product description details application methods and dosage ranges, indicating technical familiarity with brewing and feed industry practices. Buyers should independently verify the supplier's export experience, sample provision policy, and ability to supply certificate of analysis with each lot.
