What Is Wheat Fiber?

Wheat fibre is a neutral-tasting, light-coloured functional food fibre purified from the cellulose-rich part of wheat straw and bran. Total dietary fibre reaches 95–97% and is almost entirely insoluble. Water-holding capacity ranges from 1:5 to 1:9. Being tasteless and odourless, it raises fibre content without changing the sensory profile of the product.

Are wheat fibre and wheat bran the same?

No. Bran is the outer layer of the wheat kernel; it contains starch, protein, fat and minerals, is dark brown and has a characteristic taste. Wheat fibre is the purified cellulose fraction: light in colour, tasteless and almost entirely fibre. Far less wheat fibre than bran is needed to reach the same fibre content, and product colour and taste are preserved.

Applications in food manufacturing

In bread, toast and bakery it holds water, increases dough yield and delays staling; in sausages, cold cuts and meatballs it binds water and fat and raises cooking yield; in instant soups and sauces it supports viscosity; in breakfast cereals and bars it enriches fibre; in low-calorie products it provides bulk; it is also used in pet food. Typical usage is 2–5% in bakery and 1–3% in meat products.

Technical properties and quality criteria

Check total dietary fibre (≥ 95%), fibre length grade (30–500 µm), water-holding capacity (1:5–1:9), moisture (≤ 8%), colour (off-white to light beige), bulk density, residual gluten, microbiological values and heavy metals. Residual gluten is critical for products requiring a gluten-free claim.

What to check when buying

Choose the fibre length grade by application: long fibres give structure and water holding in bread, short fibres a smooth texture. If you produce gluten-free items, consider pea or cellulose fibre instead of wheat fibre; ask for a residual gluten statement. Germany, Austria and China are common origins. Obtain the specification, lot-specific COA, allergen statement and halal/kosher certificates with the quotation.

Wholesale sourcing: price and minimum order

The wholesale price of wheat fibre is set by fibre length, purity, colour, origin and order quantity. Because the product is light, freight forms a large share of the cost. The typical minimum order is one pallet. PERDIST identifies the grade suited to your application, compares sources and provides a written quotation with documents.

Frequently asked questions

Does water need adjusting when using wheat fibre in bread?

Yes; because the fibre binds water, dough water must be increased. As a rule of thumb allow about 5–7 kg extra water per 1 kg of added fibre and confirm with trials.

Is wheat fibre gluten-free?

Purification removes most gluten but residues can remain. For gluten-free claims request an analysis below 20 ppm from the supplier or choose an alternative fibre.

Does adding fibre reduce bread volume?

At high doses it dilutes the gluten network and volume can drop. In the typical 2–5% range with correct water adjustment volume is preserved; a dough improver can support it if needed.

Specification summary

The values below come from the Wheat Fiber page of the PERDIST catalogue and are confirmed per batch with the specification and certificate of analysis on every shipment.

Field	Value
Typical properties	Total dietary fibre ≥ 95–97%, water-holding capacity 1:5–1:9, moisture ≤ 8%, off-white to light beige colour, tasteless and odourless. Values vary by supplier specification.
Applications	Bread, toast and bakery, sausages, cold cuts and meatballs, instant soups and sauces, breakfast cereals, fibre-enriched and low-calorie products, pet food.
Formulation note	At 2–5% in bakery it holds water and delays staling; 1–3% in meat products. Long fibre grades give structure, short fibre grades a smooth texture.
Shelf life and storage	Typically 24–36 months in unopened packaging; store dry and odour-free.
Packaging	Typically 25 kg kraft bags with PE inner liner; pallets of 1000 kg. Big bags (500–1000 kg) considered on request.
Minimum order	Usually one pallet (1000 kg). Smaller quantities for trial production are stated in the quotation depending on product and supplier.
Origin	Common origins: Germany, Austria, China. Documented per lot in the quotation.

Documents to request from the supplier

Fibre analysis: which AOAC method was used.
Water-holding capacity: under what conditions and at what ratio it was measured.
Batch certificate of analysis and origin document, showing the number of the batch shipped.

Sample and approval steps

The steps from requesting a sample to the application trial and keeping a reference sample are set out in the ingredient sample evaluation and approval guide.

Regulatory and documentation context

A fibre claim requires the product to carry a defined amount of fibre per 100 g or per 100 kcal; the rule is set in the Turkish Food Codex nutrition and health claims regulation and, in the EU, in Regulation 1924/2006. Agree the fibre analysis method with the supplier before making the claim.
