Why Ingredient Reformulation Creates Food Manufacturing Challenges

Food manufacturers are under increasing pressure to meet changing consumer expectations. Whether it is reducing sugar, increasing protein, adding fibre, incorporating plant-based ingredients or replacing artificial additives, reformulation has become a core part of product development. 

While these changes create opportunities for innovation and growth, they also introduce new food manufacturing challenges. Ingredients that perform well in existing formulations can behave very differently when scaled up for production, affecting blending performance, flowability and product consistency. For manufacturers focused on flexible food manufacturing and future growth, adapting to these changing ingredient behaviours is becoming increasingly important.

The Reformulation Revolution

Reformulation is no longer a niche activity. Across the food industry, manufacturers are continually adapting products to improve nutritional value, enhance sustainability, meet regulatory requirements and respond to changing consumer preferences.

According to FoodDrinkEurope's guidance on product reformulation and innovation, common reformulation drivers include increasing protein and fibre content, improving nutritional profiles, adjusting formulations in response to supply chain changes, enhancing sustainability and improving product functionality and consumer acceptance. [1],[2]

Examples of reformulation currently being seen across the industry include:

• High-protein products
• Fibre-fortified foods
• Reduced-sugar recipes
• Plant-based alternatives
• Clean-label formulations
• Functional nutrition products

What manufacturers often discover is that ingredient substitutions can fundamentally change how a product behaves during processing.

Why Reformulated Ingredients Behave Differently

Traditional food formulations were often built around ingredients with predictable and well-established processing characteristics. Today's ingredients are increasingly complex.

Research and industry guidance published by IFT highlights how food manufacturers are introducing alternative proteins from peas, pulses, oilseeds, algae and fermentation-derived sources to support changing consumer trends, sustainability targets and dietary preferences. These ingredients frequently possess very different functionality compared to traditional ingredients. [4],[5]

As a result, reformulated ingredients often demonstrate:

• Higher cohesiveness
• Greater moisture sensitivity
• Variable bulk densities
• Increased electrostatic behaviour
• Poorer flow characteristics
• Increased segregation tendencies

While these characteristics may not create issues during product development, they can significantly affect large-scale manufacturing performance.

The Hidden Impact of High-Protein Formulations

One of the fastest-growing areas of reformulation is protein fortification. Industry analysis presented at IFT FIRST and reported by Food Ingredients First highlights how protein innovation has moved beyond sports nutrition into mainstream bakery, snacks, beverages and convenience foods. Manufacturers are increasingly looking for ways to add protein without creating texture, viscosity or processing issues. [6]

At the same time, ingredient suppliers report ongoing formulation challenges associated with protein fortification, including grittiness, inconsistent texture, sedimentation, viscosity changes and product hardening over shelf life.

These challenges can extend into:

• Storage
• Blending
• Material transfer
• Container discharge
• Packaging operations

Fibre Fortification is Creating New Processing Variables

Fibre enrichment remains a major area of product innovation as manufacturers seek to improve nutritional profiles while responding to consumer demand for healthier foods.

Recent reformulation guidance and market analysis show that increasing fibre content has become one of the most common objectives within modern food reformulation programmes. [3]

However, fibre ingredients can behave very differently from traditional carriers and fillers. Even relatively small additions can influence:

• Blend homogeneity
• Bulk density
• Powder flowability
• Segregation risk

This becomes particularly important when fibre is combined with high-protein formulations, where multiple ingredients often possess contrasting physical characteristics.

Reformulation is Making Clean-Label Manufacturing More Complex

The next phase of food reformulation extends beyond simply removing ingredients. According to analysis published by Food Ingredients First, manufacturers are increasingly redesigning entire formulations to maintain taste, texture, shelf life and processing performance whilst achieving clean-label objectives. [7]

In practice, this means food manufacturing teams are working with increasingly sophisticated ingredient systems that require careful consideration throughout the production process.

Why Powder Segregation Is Becoming a Bigger Risk

Another consequence of reformulation is powder segregation. As the number of speciality ingredients within a recipe increases, so too does the likelihood that ingredients may separate during handling.

Differences in the below parameters can all contribute to blend separation:

• Particle size
• Density
• Shape
• Surface characteristics

This means a blend that appears homogeneous immediately after mixing may begin to de-mix during storage, transfer or discharge. The consequences can include:

• Product inconsistency
• Nutritional variability
• Increased waste
• Rework
• Customer complaints

Protecting blend integrity throughout the manufacturing process is therefore becoming increasingly important.

Why Traditional Food Processing Systems Can Struggle to Adapt

Many existing food processing systems were designed around a relatively stable range of products and ingredients. Today's reality is very different, where manufacturers are increasingly managing:

• More SKUs
• More recipe variants
• Shorter product lifecycles
• Faster product launches
• More frequent reformulations

As ingredient innovation accelerates, systems that once performed reliably may struggle to accommodate evolving processing requirements.

Building Flexible Food Manufacturing Operations for Future Growth

Industry commentators increasingly recognise that reformulation is changing manufacturing requirements.

Manufacturers are balancing nutrition, sustainability, cost and ingredient functionality while simultaneously maintaining product quality and operational efficiency. [8]

This shift is driving demand for flexible food manufacturing approaches that can accommodate a growing variety of products and ingredient combinations.

For many businesses, the challenge extends beyond processing a single recipe successfully. It involves managing product variety in food manufacturing environments where multiple formulations, frequent recipe updates and changing consumer demands have become the norm.

The rise of multi-SKU manufacturing is further increasing complexity. Production facilities are often required to handle a wider range of products than ever before while maintaining quality, traceability and efficiency.

Future-Proof Food Manufacturing in an Era of Ingredient Innovation

The pace of ingredient innovation shows no signs of slowing. Alternative proteins, precision fermentation ingredients, fibre fortification and clean-label technologies are expected to continue influencing future food development strategies. Manufacturers that want to future-proof food manufacturing must ensure their production processes can adapt to changing ingredient characteristics without compromising product quality, efficiency or traceability.

A formulation that performs successfully during development may expose new challenges when moved into commercial production. As ingredient complexity increases, manufacturers are reassessing how powders move through their production environments and whether existing processes can support both current and future product portfolios.

Successfully managing ongoing reformulation requires processes capable of maintaining:

• Blend uniformity
• Product quality
• Operational efficiency
• Food manufacturing batch traceability
• Manufacturing flexibility
• Scalable production capacity

Many manufacturers are also evaluating how automated ingredient handling solutions can improve consistency, repeatability and process control when working with increasingly complex formulations.

For businesses pursuing scalable food manufacturing, the ability to accommodate changing ingredient behaviours without major process disruption will become a significant competitive advantage. Those best positioned for future growth will be the manufacturers that can introduce new products, adapt existing formulations and manage increasing product variety without compromising operational performance.

Frequently Asked Questions

Why is food reformulation becoming more common?

Food reformulation has become a priority as manufacturers respond to demand for healthier products, increased protein and fibre content, clean-label ingredients and more sustainable food choices. While these changes help brands remain competitive, they also introduce new processing variables. Ingredients that perform well in an existing formulation may behave very differently when substituted or enhanced, creating challenges with blending, flowability and product consistency that must be carefully managed during scale-up.

Why do reformulated ingredients create manufacturing challenges?

Reformulated ingredients often have different physical properties to the materials they replace. Changes in particle size, density, moisture sensitivity or ingredient functionality can affect how powders blend, flow and discharge. In practice, this can lead to longer mixing times, segregation, inconsistent batch quality, increased cleaning requirements and reduced production efficiency if manufacturing processes are not adapted to accommodate the new ingredient characteristics.

Why are high-protein powders more difficult to process?

High-protein ingredients are typically more cohesive than traditional food powders and can be prone to compaction, bridging and inconsistent flow. As protein levels within a formulation increase, manufacturers may encounter difficulties achieving blend uniformity, maintaining reliable discharge and preventing material build-up within equipment. These challenges can impact throughput, increase waste and make it harder to achieve consistent product quality from batch to batch.

How can fibre affect powder blending?

Fibre ingredients can significantly alter the physical behaviour of a formulation. They may affect bulk density, powder flow and how ingredients interact during mixing. In some applications, fibre can make it more difficult to achieve and maintain a homogeneous blend, increasing the risk of segregation during storage, transfer or discharge. This can result in variations in nutritional content, flavour and texture across the final product.

What food trends are likely to drive future reformulation?

Protein fortification, fibre enrichment, plant-based ingredients, alternative proteins and clean-label development are expected to remain major drivers of food innovation. As manufacturers continue expanding product portfolios to meet changing consumer demand, many will face increasing challenges associated with multi-SKU manufacturing, ingredient variability and maintaining consistent product quality at scale. The businesses best positioned for future growth will be those that adopt flexible food manufacturing strategies capable of supporting innovation whilst maintaining efficiency, traceability and production performance.
