What Is Soy Fiber?

Soy fibre is a food fibre obtained from soybean hulls (hull fibre) or from okara, the pulp left over from soy milk and tofu production. Total dietary fibre ranges from 60% to 90%. Its water-holding capacity is high and it has long been an economical fibre source in meat products.

Functional properties

It binds 5–8 times its own weight in water; in meat emulsions it reduces water and fat loss, improves cooking yield and sliceability. In bakery it retains moisture. Because it contains residual soy protein it can carry a mild legume note; where a neutral taste is required, pea or cellulose fibre is preferred.

Allergen status and labelling

Soy is among the allergens requiring mandatory declaration under Turkish and EU regulations. Products using soy fibre must declare soy on the label. Manufacturers wishing to avoid an allergen declaration turn to alternatives such as pea fibre, cellulose fibre or wheat fibre.

Applications

Sausages, cold cuts, meatballs and processed meat; burger and mince blends; bakery; instant soups and sauces; extruded products; pet food. Typical usage in meat products is 1–3%.

Technical properties and quality criteria

Check total dietary fibre, water-holding capacity, residual protein, particle size, moisture, colour, non-GMO statement, allergen statement and microbiological values. Non-GMO documentation for soy is expected in many markets.

Sourcing from PERDIST

Soy fibre is not in PERDIST's standard catalogue; sourcing is researched on request. Write with your application, target water-holding value and monthly volume and we present suitable sources with documents in a written quotation. For formulations that must avoid an allergen declaration we can also evaluate pea fibre.

Frequently asked questions

How do I choose between soy fibre and pea fibre?

Soy fibre is usually cheaper but requires an allergen declaration. Pea fibre needs no allergen declaration and is more neutral in taste; it is preferred for clean-label targets.

Is soy fibre GMO?

It depends on the source. If a non-GMO statement is required, ask the supplier for IP (identity preserved) certified product.

How much water does it hold in a meat product?

5–8 times its own weight depending on grade. Adjust added water to the fibre level in the recipe and run a yield trial.
