Question 1

What is xylanase enzyme used for?

Accepted Answer

Xylanase breaks down xylan, the primary hemicellulose in cereal crops and hardwoods. Commercial applications include: baking (increases loaf volume, improves dough handling), animal feed (improves digestibility in poultry and swine), pulp and paper manufacturing (reduces bleaching chemical requirements by up to 20%), and biofuel production (releases fermentable sugars from lignocellulosic biomass).

Question 2

What is the optimum temperature and pH for xylanase activity?

Accepted Answer

Fungal xylanases (Trichoderma reesei, Aspergillus niger) are most active at pH 4.5–6.0 and 50–60°C. Bacterial xylanases can be active at higher temperatures (up to 80°C for thermostable variants). Our baking-grade xylanase is optimized for dough temperatures of 25–40°C at pH 5.0–5.5.

Question 3

What is the difference between endo-xylanase and beta-xylosidase?

Accepted Answer

Endo-xylanase cleaves internal xylosidic bonds along the xylan backbone, rapidly reducing viscosity and producing short xylo-oligomers. Beta-xylosidase then releases individual xylose units from the ends of these oligomers. Full hydrolysis to xylose requires both enzymes, but most baking and feed applications only need endo-xylanase.

Question 4

How much xylanase should I add to bread dough?

Accepted Answer

Typical baking dosage is 10–100 XU/kg of flour, depending on the xylanase preparation's activity and the target dough consistency. We provide application-specific dosage recommendations with every order. Sample kits (1 kg) include a technical data sheet with suggested starting dosages.

Question 5

Can I order a small sample before buying in bulk?

Accepted Answer

Yes. Our minimum order quantity is 1 kg. This is suitable for lab testing, pilot trials, and small-batch production. Once you confirm performance, you can scale up without any change in the enzyme preparation — we ship the same product specification at all quantities.

Question 6

Do you provide a certificate of analysis with xylanase orders?

Accepted Answer

Yes. Every batch ships with a certificate of analysis (CoA) confirming enzyme activity in XU/g or FXU/g, pH range, temperature optimum, moisture content, and microbiological specifications. Technical data sheets and safety data sheets (SDS) are available on request.
