How to increase fibre in food formulations without compromising on texture

  • Posted on:

Increasing dietary fibre sounds straightforward until a product becomes gritty, dry, too thick, or difficult to process. For food manufacturers, the real challenge is to improve fibre content while retaining the taste, texture and consistency customers expect. At 1-2-Taste, we believe successful fibre fortification starts with choosing the right ingredient for the application, not simply the ingredient with the highest fibre percentage.When to consider liquid fibre syrups:

Why adding dietary fibre requires a formulation-first approach

Taste, texture and mouthfeel are just as important as nutritional value when increasing dietary fibre in food formulations. Depending on the fibre type and inclusion level, it can affect sweetness, viscosity, moisture retention and the overall sensory experience. For example, some fibres may make bakery products feel drier or denser, while others can change the thickness, smoothness or consistency of beverages. Choosing the right fibre for the intended application helps manufacturers achieve their nutritional goals while maintaining the product qualities consumers expect.

Solubility and processing conditions also play an important role in fibre performance. Factors such as heat, pH, mixing intensity and water availability can influence how an ingredient behaves during manufacturing. These variables may affect dispersion, stability, binding and the final product structure. Evaluating them early in the formulation process helps R&D teams identify potential challenges, optimise ingredient inclusion levels and reduce the risk of costly reformulation during commercial production.

Choosing the right fibre for different food applications

To increase fibre content in bakery formulations

Start by assessing moisture, dough handling, crumb structure and shelf life. A suitable fibre powder may help increase fibre content, but the formulation may need adjustments to water levels and baking conditions. Adding fibre to bars and snacks requires attention to binding, chewiness, hardness and moisture migration.

The best ways to increase fibre in beverage formulations

Evaluate solubility, clarity where relevant, sedimentation, viscosity and stability throughout shelf life. For nutrition formulations, consider serving size, dispersibility, taste and compatibility with proteins, sweeteners and other ingredients.

 

Why fibre concentration alone is not enough

A fibre ingredient offering a high fibre percentage may look attractive on paper, but it is not automatically the best choice. Compare its performance at the intended inclusion rate, its effect on the finished product, processing requirements, supply consistency and cost per effective serving. Procurement teams should evaluate total formulation cost, while R&D teams assess whether the ingredient delivers the required functionality.

 

Resistant dextrin powders versus liquid fibre syrups

When to consider powder-based fibres:

Resistant dextrin powders can be useful in dry blends, nutrition powders, bars and selected bakery or snack applications. You can explore OligoSMART RD TP90 tapioca resistant dextrin powder, OligoSMART RD CP90 corn resistant dextrin powder and OligoSMART Tapioca RDP 70

When to consider liquid fibre syrups:

Liquid formats may suit formulations where syrup handling fits the existing process and the ingredient contributes to the desired solids or texture. Assess water contribution, pumping, storage and mixing requirements before comparing options.

The OligoSMART RD TS90 tapioca resistant dextrin syrup offers another option for manufacturers exploring fibre enrichment. Compare it with the powder variants based on physical format, declared fibre content, processing behaviour and application requirements. Always confirm current technical specifications and suitability with the supplier before selecting an ingredient for commercial production.

 

How to plan effective F&B prototype trials

Start with a control recipe and test two or three inclusion levels. Keep other variables consistent wherever possible. Measure fibre content, taste, texture, viscosity where relevant, processing performance and shelf-life stability. Record ingredient costs and any changes needed to water, binding agents or processing conditions. Evaluate the finished product after processing, not just the ingredient before mixing. This approach helps identify a workable balance between nutritional targets and consumer acceptance.

 

Conclusion

Increasing fibre without compromising texture is a formulation challenge, not a numbers game. By matching fibre type to the application, comparing powders and syrups, and conducting structured prototype trials, manufacturers can make better technical and commercial decisions. At 1-2-Taste, our OligoSMART range provides options to explore for fibre-enriched food and beverage development. The next step is to identify your product’s needs and test the ingredient that fits them best.

Frequently asked questions

The best option depends on the application, fibre target, solubility, taste and processing conditions. 

Yes. Depending on the fibre and inclusion rate, it may affect moisture, crumb structure and dough handling.

It may be suitable for selected beverages, but solubility, viscosity, stability and sensory performance should be tested.

Neither is universally better. Choose based on formulation requirements, process compatibility and total cost. 

Confirm the analytical fibre content of the finished product and check applicable FSSAI requirements before making a claim.
