Fungal Alpha Amylase

Fungal Alpha Amylase*-BRIEF

This product fits to starch liquefaction and also saccharification, allowing its wide usage in grain processing industry, e.g. maltose and high maltose production. It converts liquefied starch slurry to maltose syrups in a highly efficient way.

Fungal Alpha Amylase Description

Fungal Alpha-Amylase Boli FAA***0 is made from Aspergillus oryzaevar. through deep fermentation and refining extraction technique. This enzyme can be used for starch liquefaction and also saccharification to produce maltose and glucose. It is an endoamylase which can rapidly hydrolyze the interior alpha*1, 4 glucosidic linkages of gelatinized starch, amylose and amylopectin solution and produce soluble dextrins 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.

Fungal Alpha Amylase Characteristics

Fungal Alpha Amylase Effect Of PH

The optimum pH range of Fungal Alpha Amylase Boli FAA***0 is 4.8 ~ 5.4. Starch can be effectively hydrolyzed at pH range 4.0 ~ 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.

Fungal Alpha Amylase Effect Of Temperature

Optimum temperature range is *5 ~ *5°C and effective temperature range is *5 ~ *5 °C.

Optimum temperature of this product is *0°C. It can efficiently hydrolyze starch at a temperature range of *5 ~ *5°C. If the content of starch is higher, the reaction temperature can be raised to *5°C. The optimum temperature range is affected by pH, within *5 ~ *5°C.

Fungal Alpha Amylase Inactivation

Inactivation can be achieved by raising the temperature to *0 ~ **0°C and keep for 5 ~*0 minutes. If the content of starch is higher, this product can be inactivated by keeping the temperature at *0°C for about *0 minutes, or *0°C for about *0 minutes. If inactivation by high temperature is not preferred, another option of inactivation is to decrease the pH to 4.0 and below. Inactivation can also be realized by adjusting pH and temperature at the same time.

Fungal Alpha Amylase Inhibitors

Fungal Alpha Amylase Boli FAA***0 can be inhibited by several heavy metal ions. Copper and lead ions are strong inhibitors. Inhibitive effects can also be achieved if the content of zinc, nickel and iron ions are high.

Fungal Alpha Amylase Substrate

Fungal Alpha Amylase Boli FAA***0 is applicable for saccharification of corn, potato, tapioca, wheat, soyabean and starches from other resources. It can hydrolyze effectively if the content of starch is no more than *0% on dry solid base (DSB).

Fungal Alpha Amylase Usage Guiedlines

In general, the dosage depends on the desired maltose content in the final syrup and the saccharification time. Typical dosage of Fungal Alpha Amylase Boli FAA***0 is 0.1 ~ 0.5 kg/TDS.
