Heat Stable Alpha Amylase

Heat Stable Alpha Amylase HS‑400 is an endo‑amylase produced by submerged fermentation of Bacillus licheniformis and supplied as a light to dark brown liquid. The enzyme delivers a minimum activity of 40 000 U ml⁻¹ and operates effectively at a product pH of 5.8 to 6.8, with an optimal pH window of 6.0 to 6.4. Its specific gravity ranges from 1.15 to 1.25 g ml⁻¹, and the formulation remains stable across a pH range of 5.0 to 10.0.

The HS‑400 preparation is packaged in 25 kg or 30 kg non‑hazardous plastic drums and also in 1 200 kg IBC totes, which matches the standard bulk handling practice for industrial enzymes. Typical enzyme preparations for starch liquefaction exhibit activity levels between 10 000 and 100 000 U ml⁻¹, and a common storage temperature is 2 to 8 °C, so the supplier’s recommended shelf‑life of six months below 25 °C and eighteen months at 0 to 10 °C aligns with industry norms. The enzyme’s thermal profile shows peak activity above 90 °C, efficient liquefaction at 95‑97 °C, and retained activity up to 100 °C, while stability persists for 5‑7 minutes at 105‑110 °C, which is typical for heat‑stable amylases used in ethanol‑based starch processing.

In the ethanol industry the enzyme is added during starch liquefaction to rapidly reduce viscosity and generate soluble dextrins, a step commonly required by large‑scale fermenters. Buyers such as ethanol producers, starch converters and feed manufacturers usually request bulk drums or IBC containers and specify Incoterms such as FOB or CIF together with payment terms of L/C at sight. Prospective importers should confirm the exact MOQ, lead time and any required certificates directly with Jiangsu Boli Bioproducts before finalising the contract.

Jiangsu Boli Bioproducts Co., Ltd. is located at 93 Yangzhou Road Development Zone, Taizhou, Jiangsu 225500, China. The company is classified as an imported tier supplier and carries a harbor trust tier, indicating that it has been verified through third‑party checks. Its response metrics show a response rate of 0 % and an average response time of 0 hours, which suggests that communication may require proactive follow‑up.

The firm specialises in the production and refinement of microbial enzymes such as the heat‑stable Alpha‑Amylase HS‑400. While the listing does not disclose certifications, production is performed via submerged fermentation and extraction processes that meet standard bioproduct manufacturing practices. Interested buyers should request further documentation on quality management systems before placing an order.
