FUNGAL ALPHA-AMYLASE FAA-280 – PRODUCTION OF MALLT, STARCH SUGAR

FAA-280 is an end-amylase that facilitates the rapid and thorough hydrolysis of the internal α-1,4 glucosidic bonds of starch, amylose and amylopectin to produce large amounts of maltose syrup and small amounts of sugar if the reaction lasts for a longer time.

Product information:

Enzyme ingredients: Fungal Alpha-Amylase

System name: EC 3.2.1.1.1,4-α-D-Glucan glucanohydrolase

Potency: ≥28,000 U/ml

Appearance: liquid, clear to dark brown.

pH: 5,5 đến 7,0

Density: 1.15 to 1.25 g/ml

Impact of pH on FAA-280:

The optimal pH range of this product is from 4.8 ~ 5.4, and starch can be effectively hydrolyzed at a pH range of 4.0 ~ 6.6.

If enzyme stability is a concern, reactions should be performed at a pH above 5.5.

If reaction rate is important, the pH should be adjusted below 5.5.

Impact of temperature on FAA-280:

The optimal temperature range is 45 ~ 55 oC and

The effective temperature range is 45 ~ 65 oC.

The optimal temperature point of this product is 50°C.

The optimal temperature range is influenced by pH, between 45 ~ 65°C

Enzyme inactivation:

Can be deactivated by increasing the temperature to 90 ~ 100°C and maintaining this temperature for about 5 ~ 10 minutes.

If the starch content is high, this product can be inactivated by holding at 80oC for about 30 minutes or 70oC for about 60 minutes.

If high temperature inactivation is not desired, the pH can be reduced below 4.0.

Enzyme inactivation can also be accomplished by simultaneously adjusting the pH and temperature.

Usage:

Dosage used depends on desired maltose content and saccharification time, typical dosage of FAA-280 is approximately 75-500 grams per ton dry powder (TDS)

However, the exact dosage of FAA-280 depends on the actual situation such as: starch substrate, liquefaction equipment, processing conditions... To optimize the dosage, it is necessary to conduct some liquefaction tests to find the optimal dosage suitable for each product. plants.
