Jiangsu Boli Bioproducts Co., Ltd. is a professional manufacturer of quality and cost-effective enzymes that bring added-value to our customers. With more than twenty years expertise in enzyme research and development, Boli Bioproducts has been recognized as a reliable partner that helps to improve their bottom-line because of consistent high quality, competitive price and unparalleled excellent services.

The history of Boli Bioproducts can be traced back to 1998, when its co-founders started with an enzyme consulting company specialized in enzyme design and commercialization in response to the specific needs of its customers. With the rapid growth of enzyme industry in China, in order to better serve customers, its co-founders set up a world-class production facility in 2005 in Jiangyan Economic Development Zone (about 230 km northwest to Shanghai), Jiangsu Province. The plant covers an area of approximately 20,000 m2, with annual enzyme production capacity of 30,000 MT.

Boli Bioproducts's enzyme products can be divided into industrial grade and food grade, and are available in both liquid and solid (powder) forms. Among the many varied applications for these enzymes are: fuel ethanol production, grain processing, food baking, brewing, textiles and animal feed. Our top products such as Glucoamylase, Alpha Amylase, Beta-Glucanase, Catalsae and Protease are widely accepted and highly appreciated by our customers because of the benefits --- higher enzyme activity, superior pH and thermal stability, greater starch-ethanol conversion rate, less enzyme dosage, less emission of waste, easier processing, more output --- that are greatly helpful to improve their bottom line.

The continuous and sustainable growth of Boli Bioproducts is the result of the dedication of the team of management, researchers, engineers and operators, and in particular, the valuable support from customers. Commitment, Integrity, Strive for Customer Satisfaction, that is how Boli Bioproducts will serve you as your reliable partner and bring added-value to your business.

 An ideal Alpha-Amylase with the following benefits for starch sugar production:

1.Decrease viscosity of starch quickly

2.Decrease formation of chromophore

3.Eliminate non-fermentable sugars

4.Highly efficient liquefaction

5.Capable to handle various starch materials, such as tapioca, corn, wheat and rice

Description
HS-320 is a thermostable Alpha-Amylase derived from Bacillus licheniformis. It is an endoamylase that hydrolyzes alpha-1, 4-glucosidic bonds to quickly reduce the viscosity of gelatinized starch, producing soluble dextrins and oligosaccharides under various process conditions.

Product Characteristics

Effect of pH
HS-320 is active over a wide pH range depending on the actual applications. For maximum activity, the optimal pH is 6.0 to 6.4. The stable pH range is 5.0 to 10.0 at temperature of 25° C. The exact pH optimum depends on actual processing conditions, such as temperature, substrate concentration and time.

Effect of Temperature
Optimum temperature of HS-320 for interval liquefaction is above 90° C. It liquefies starch substrates promptly at 95 to 97° C and is till highly active at 100° C. This product demonstrates exceptional thermal stability at temperatures from 105 to 110° C, maintaining its stability for 5 to 7 minutes, keeping on liquefying rapidly and completely. The exact temperature optimum of this product depends on various processing conditions, including pH, substrate concentration and time.

Concentration of Calcium
The presence of calcium increases the thermal stability of HS-320. It requires a very low calcium concentration and calcium additions of 50 to 70 ppm (dry solid basis) are sufficient to ensure its enzyme stability.

Inhibitors
Copper, titanium, and cobalt ions are moderate inhibitors for HS-320, whereas aluminum, lead and zinc ions act as strong inhibitors.

Usage Guidelines
In general, first adjust the pH at 6.0 to 6.4 and then add calcium (50 to 70 ppm dry solids basis) before adding HS-320. Calcium is not necessarily needed when extremely hard water (>10 German degrees) is used. After the enzyme is added, heat the slurry to liquefy.

Dosage
Dosage of HS-320 varies and is dependent on the starch substrate, application, process, substrate concentration, and other factors. To optimize the dosage, it is recommended to conduct a number of liquefaction trials prior to routine use of this product. A good starting point for dosage rate is 0.2 to 0.6kg/TDS.

Packing
HS-320 is packaged in 25kg, 30kg non-hazardous plastic drums or 1200kg IBC totes. Customized packaging is available upon request.

Storage
HS-320 should be stored below 25° C in its original packaging, sealed and unopened, protected from the sun. This enzyme has been formulated for optimal stability. However, enzymes gradually lose activity over time. Extended storage and/or adverse conditions such as higher temperature may lead to a higher dosage requirement.

Safety & Enzyme Handling
Inhalation of enzyme dust and mists should be avoided. In case of contact with the skin or eyes, promptly rinse with water for at least 15 minutes. For detailed handling information, please refer to the appropriate Material Safety Data Sheet.
