Import Alkaline Protease — Buy in Bulk from Supplier in China

This alkaline protease is a serine endopeptidase derived from Bacillus licheniformis 2709, a workhorse strain in industrial enzyme production known for robust extracellular protease secretion. The enzyme catalyses the hydrolysis of peptide bonds in proteins, functioning optimally under alkaline conditions. Sunson Industry Group Co., Ltd. supplies this product for food processing, brewing, animal feed and protein hydrolysate applications, with activity levels and stability parameters suited to large-scale manufacturing. The supplier is headquartered in Beijing with operational presence in enzyme manufacturing regions of China.

Bacillus licheniformis 2709 alkaline protease typically demonstrates maximum activity at pH 9.0 to 11.0 and temperatures of 50 to 60 degrees Celsius, though exact kinetic parameters depend on substrate and ionic strength. The enzyme is produced by submerged fermentation, followed by recovery, concentration and standardisation, usually as a liquid or granulated solid formulation. Stability across broad pH and temperature ranges is a key commercial advantage, reducing the need for tight process control. Industrial grades may contain stabilisers such as glycerol, salts or approved preservatives; buyers should request the exact formulation, declared activity in units per gram or millilitre, and whether the product is food-grade, feed-grade or technical grade.

Primary buyers include meat processors seeking tenderisation and flavour enhancement, dairy manufacturers producing protein hydrolysates for infant or sports nutrition, breweries requiring adjunct protein degradation for filtration efficiency, and compound feed producers improving protein digestibility in monogastric animals. The enzyme is also used in detergent formulations and leather processing, though these applications may require different grade specifications. Importers should confirm with Sunson Industry Group whether the supplied grade meets the intended application regulatory requirements, such as food enzyme regulation in the EU or GRAS status considerations in the United States. All MOQ, pricing, lead time and certification claims must be verified directly with the supplier, as the source description contains promotional assertions that require independent confirmation.

Sunson Industry Group Co., Ltd. maintains its registered office at Suite 628, China Minmetals Building, Block 4, Anhuili, Chaoyang District, Beijing 100101, China. The supplier carries an imported tier designation and a harbor trust tier, with published response metrics showing zero response rate and zero average response hours. This lack of engagement history means buyers should treat initial contact as exploratory and request direct communication channels, referenceable export experience, and evidence of active customer support before relying on stated capabilities. The source description attributes various quality and service claims to the supplier, though these should be treated as unverified until documented.

The company positions itself as a manufacturer of industrial enzymes for food, beverage, feed and adjacent sectors. No factory location, production capacity, year of establishment, employee count, revenue, audited financials or named client list appears in the source data, so none should be invented. Beijing address may indicate corporate headquarters rather than manufacturing site; enzyme fermentation typically occurs in dedicated production facilities, often in provincial industrial zones with appropriate environmental permits. Buyers should request the manufacturing site address, fermentation capacity, quality management certification scope (ISO 9001, ISO 22000, FSSC 22000), and any customer audit reports. Verification of FSSAI certification is particularly relevant if the supplier claims Indian market access, while EU buyers should request food enzyme regulation compliance documentation including the enzyme's place on the Union list or novel food status.
