Use Cases

Applications

Alpha-Amylase catalyzes the hydrolysis of starch into dextrins and fermentable sugars, helping improve yield, viscosity control, and downstream processing performance across baking, brewing, syrup production, textile desizing, paper & pulp sizing, and ethanol manufacturing.

1
🍞

Baking & Flour Treatment

Hydrolyzes damaged starch in flour to produce fermentable sugars, improving bread volume, crumb softness, and shelf life.

2
🍺

Brewing & Distilling

Liquefies starch in mash at high temperatures (85–95°C), converting gelatinized starch into dextrins for saccharification.

3
🏭

Starch Liquefaction

First-stage enzyme in glucose/fructose syrup production. Converts raw starch slurry into soluble dextrins at industrial scale.

4
🧵

Textile Desizing

Removes starch-based sizing agents from woven fabrics before dyeing, ensuring even dye uptake without fiber damage.

5
📄

Paper & Pulp

Modifies starch coatings for surface sizing and coating applications, controlling viscosity and improving paper printability.

6
🍶

Ethanol Production

High-temperature liquefaction of corn and cassava starch for fuel ethanol, reducing viscosity and enabling downstream saccharification.

FAQ

Frequently Asked Questions

Q1 What is Alpha-Amylase (EC 3.2.1.1) used for?

Alpha-Amylase hydrolyzes starch into dextrins and fermentable sugars. It is used for baking & flour treatment, brewing & distilling, starch liquefaction for glucose/fructose syrup, textile desizing, paper & pulp starch modification, and ethanol production to reduce viscosity and enable downstream saccharification.

Q2 What are the optimal pH and temperature for Alpha-Amylase?

For best performance, use Alpha-Amylase at pH 5.5–7.0 and 70°C–95°C.

Q3 How do I choose between standard and thermostable grades?

Use the standard grade (20,000–40,000 U/g) for typical liquefaction conditions, and consider the thermostable grade (60,000 U/g) when you need stronger performance under higher-temperature processing or longer holding times.

Q4 How should I store Alpha-Amylase to maintain activity?

Store the enzyme in a sealed container in a cool, dry place. Shelf life is 12 months under proper storage conditions.

Q5 What packaging options are available and what is the MOQ?

Powder is supplied in 25 kg drums and liquid is supplied in 30 kg jerricans. MOQ is 25 kg.
