Non - GMO Liquid Fungal Alpha-Amylase FA-280 

Stable Activity Enzyme Brewing

Suitable for both liquefaction and saccharification of starch materials , 

Non-GMO,  Halal & Kosher Certified,

DESCRIPTION:

• Fungal Alpha-Amylase FA-280 is made from Non-GMO strains of Aspergillus oryzae by submerged fermentation and refining extraction process. It can be used for starch liquefaction and also saccharification to produce maltose and glucose. As anendoamylase, FA-280 can rapidly hydrolyze the interior α-1, 4 glucosidic linkages of gelatinized starch, amylose and amylopectin solution and produce soluble dextrin and a small quantity of glucose and maltose. It can also produce syrups of high maltose and a small quantity of glucose if the reaction lasts for longer time.

PRODUCT CHARACTERISTICS

EFFECT OF PH:

• The optimum pH range of this product is 4.8 to 5.4 and starch can be effectively hydrolyzed at pH range 4.0 to 6.6. If the stability of enzyme is emphasized, the reaction should be conducted at pH above 5.5. If the reaction rate is emphasized, the pH should be below 5.5. See Figure 1.

EFFECT OF TEMPERATURE:

• Optimum temperature range is 45 to 55°C and effective temperature range is 45 to 65°C. Optimum temperature of this product is 50°C. It can efficiently hydrolyze starch at a temperature range of 45 to 55°C. If the content of starch is higher, the reaction temperature can be raised to 65°C. The optimum temperature range is affected by pH, within 45 to 65°C. See Figure 2.

INACTIVATION:

• Inactivation of FA-280 can be achieved by raising the temperature to the range of 90 to 100°C and maintaining for approximately 5 to 10 minutes. If the content of starch is higher, this product can be inactivated by keeping the temperature at 80°C for about 30 minutes, or 70°C for about 60 minutes. If inactivation by high temperature is not desirable, another option of inactivation is to decrease the pH below 4.0. Inactivation can also be realized by adjusting pH and temperature at the same time.

INHIBITORS:

• This product may be inhibited by several heavy metal ions. Copper and lead ions are strong inhibitors. Inhibitive effects may also be achieved if the content of zinc, nickel and iron ions are high.

SUBSTRATE:

• This product is applied to saccharify starches from corn, potato, tapioca, wheat, soybean and other resources. It can hydrolyze effectively if the content of starch on the dry substrate basis (DSB) is no more than 50%.

SAFETY AND HANDLING PRECAUTIONS

Inhalation of dust or aerosols should be avoided due to enzymes may cause allergic reactions in sensitized individuals. Splashing should be avoided. Spilled product should be flushed away with water immediately. Wear suitable protective gloves, safety glasses and nose covers. In case of contact with the skin or eyes, promptly rinse with water for at least 15 minutes. Refer to the Material Safety Data Sheet for further information regarding how to handle the product safely.
