What Is Xylanase Used For?

Enzymes play a critical role in improving product quality, consistency, and efficiency in modern world. Xylanase is one such enzyme that has become increasingly important, particularly in baking and cereal-based applications. But what exactly is xylanase, and what is it used for? Let`s get a comprehensive overview.

 

What Is Xylanase Enzyme?

 

Xylanase is a naturally occurring enzyme that breaks down xylan, a type of hemicellulose found in plant cell walls-especially in cereal grains like wheat, rye, and barley. Chemically speaking, xylan is a polysaccharide composed of xylose sugars, and xylanase hydrolyzes the β-1,4-glycosidic bonds in this structure.

 

The enzyme is commonly produced through microbial fermentation, using strains of fungi (like Aspergillus niger) or bacteria (Bacillus subtilis), making it suitable for food use.

 

 

What Is Xylanase Used For in the Food Industry?

 

1. Baking Industry

 

Xylanase is most widely used in bread and baked goods. It improves dough handling and final product quality by:

Enhancing dough strength and elasticity

Increasing bread volume and softness

Improving crumb structure and shelf life

Reducing the need for chemical dough conditioners

By breaking down arabinoxylans (a form of hemicellulose in flour), xylanase releases bound water and improves gluten network development. This makes the dough easier to handle and yields better texture in the final product.

Example: In whole wheat bread, where bran content often disrupts gluten structure, xylanase helps soften the impact and maintain product quality.

 

2. Cereal Processing

 

In breakfast cereals and extruded grain products, xylanase helps:

Improve processability of high-fiber cereals

Enhance texture and mouthfeel

Support extrusion by modifying fiber structure

 

3. Beverage Production (e.g., beer and fruit juice)

 

Xylanase is also used during clarification and filtration processes:

In brewing, it helps break down non-starch polysaccharides, improving wort separation and filtration.

In fruit juices, it reduces viscosity and improves juice yield and clarity, especially when combined with other enzymes like pectinase.

 

4. Animal Feed

 

Though not a food use, it's worth mentioning that xylanase is commonly added to animal feed (especially poultry diets) to improve nutrient digestibility by breaking down plant cell walls and improving energy release.

 

 

Is Xylanase Safe?

 

Yes. Xylanase is considered safe for food use by major food safety authorities, including:

FDA (U.S.) – GRAS status when produced by approved microbial strains.

EFSA (EU) – Evaluated and permitted under enzyme regulations.

GB Standards (China) – Approved for use in flour and baking.

When used properly, xylanase is not active in the final baked product, as it is deactivated by oven temperatures during baking.

 

Final Thoughts

 

Xylanase is a versatile, naturally derived enzyme that plays a key role in modern food processing-especially in the baking and grain sectors. By improving dough behavior, enhancing texture, and extending shelf life, it helps manufacturers meet consumer expectations for both quality and clean label solutions.

 

If you're formulating bread, rolls, or other flour-based products, xylanase could be a game-changer in your enzyme toolbox.
