Angel Thermo-Stable Alpha-Amylase AHA-100d

DESCRIPTION

Angel Thermo-Stable Alpha-Amylase AHA-100D is a food-grade starch hydrolyzing α-amylase with high temperature and low pH stability derived from Bacillus licheniformis.

Characteristics

Name:Thermo-Stable Acid α–Amylase AHA-100D

System name:EC.3.2.1.1, 1,4-α-D-Glucan-glucanohydrolase

Activity: 100,000U/mL (minimum)

Appearance: brown liquid

pH: 6.0 to 7.0

Specific gravity: 1.15 to 1.25 g/ml

Effect of pH

The enzyme is stable in the range of pH5.0 to 10.0, and effective in the range of pH5.0 to 7.0, the optimum pH is in the range of 5.4 to 6.0.

Effect of Temperature

The enzyme own excellent thermostability, the optimum temperature is above 95℃, with most effective jet temperature in the range of 105℃ to 110℃. The enzyme maintains considerable activity at higher temperatures (110℃ or above).

The product is suitable for all kinds of jet cookers, and able to prevent the production fluctuation from steam pressure instability.

mechanism

The enzyme is an endoenzyme that is able to hydrolyze the α-1,4 glycosidic bonds in starch, soluble dextrin, and low-polysaccharides under high temperatures. This enzyme is also able to quickly reduce viscosity of starch slurries to facilitate further handling and processing.

Applications and Usage

This product can be used in production of starch sugar, fermentation industries such as monosodium glutamate, antibiotics, citric acid, and amino acid. The recommended for optimum industry operation condition is temperature 95℃~100℃, whereas if steam jet method is used, temperature may increase to 105-110℃, pH 5.4 ~6.0.

Usage:  

Mix ingredients with water according to specification, adjust the pH, and add 0.25~0.3kg of enzyme to each ton of dry ingredient. If liquefying is done in a tank, heat the tank to 95℃-100℃ and hold the temperature for approximately 30 minutes.

Whereas if steam jet method is used, heat steam jet nozzles to 105±5℃ and transfer to flash tank at about 105℃for 5-10min, then transfer to laminar flow tank, sustain 90-120min at 95℃ or until viscosity and DE value meet the production requirements.

Specifications

liquid, 100,000U/mL

Sealed in Plastic Bucket; Net Weight 28kg/bucket or 1000kg/bucket.

Storage

The product if stored at 25℃ below, at least 12month shelf life, if under the 4~10℃ cold storage, shelf life is 18 months; under warranty, measured activity not less marked activity. Over shelf life, enzymes may decrease, but can still be used, usage should be increased accordingly.
