Protein is no longer the industry’s biggest challenge – formulation is

Whether the discussion centred on plant-based foods, sports nutrition, functional beverages or healthy ageing, the underlying assumption was largely the same: consumers wanted more protein, and the industry's challenge was finding effective ways to deliver it.

Although the protein market has matured, headlines focus on slow growth in certain categories such as plant-based meat, which risks obscuring more significant shifts across the wider food and beverage industry: Consumers have not fallen out of love with protein. They have fallen out of love with protein products that do not taste good.

Consumers continue to prioritise protein in modern diets, but they are no longer willing to compromise on taste, texture or overall eating experience. As protein moves beyond specialist nutrition into mainstream food and beverage categories, the challenge is not to add protein but to formulate products that deliver meaningful nutrition while maintaining the sensory qualities consumers expect.

Priority protein

The nutritional argument for protein is straightforward, and consumers understand its role in promoting satiety, muscle maintenance, active lifestyles and healthy ageing. The rapid growth of GLP-1 medications is increasing consumer interest in nutrient-dense foods. As people eat smaller portions, manufacturers face greater pressure to deliver meaningful levels of protein and nutrition in more compact formats.

This development has significant implications for product development. The industry is beginning to see growing demand for products capable of delivering higher levels of protein within smaller serving sizes and more convenient consumption formats.

Functional beverages, snack bars, bakery products, meal replacement solutions and on-the-go nutrition formats are all being asked to provide greater nutritional value within compact eating occasions. Yet while nutritional expectations are increasing, consumer expectations around taste, texture and enjoyment remain unchanged. It is at this point that new product development becomes considerably more complex.

Complex formulation challenges

For many years, products high in protein had a niche positioning, and consumers were often willing to compromise on taste or texture as long as the functional benefit was clear. But as high protein moves into everyday food and beverage categories, these compromises are no longer acceptable.

Today's consumers are not comparing protein-enriched products with the sports nutrition products of a decade ago, but with the best products available in each category. A protein cookie has to compete with premium bakery products, fortified beverages must hold their own next to café-quality drinks, while high-protein snacks must deliver on overall eating pleasure. Although nutritional benefits may encourage a consumer to try a product for the first time, repeat purchase behaviour is still driven overwhelmingly by sensory experience.

No longer a differentiator

The consequence is that protein alone is no longer a differentiator. Great taste coupled with protein is. However, adding protein ingredients can introduce technical challenges that actively work against a great eating experience.

Protein is nutritionally valuable but also disruptive. In beverages, higher protein inclusion can create viscosity challenges, chalky mouthfeel, sedimentation issues and flavour imbalances. In baked goods, protein can influence structure development, moisture retention and dough softness throughout shelf life. In snacks and bars, protein interactions can affect texture stability, resulting in products that become progressively harder or less appealing over time. Plant proteins can also introduce grassy, bitter or beany flavour notes, while some dairy proteins contribute a dry mouthfeel - diminishing overall enjoyment.

These challenges become even more pronounced as manufacturers attempt to balance multiple consumer demands simultaneously. Today's consumers are looking for products that are high in protein, formulated with recognisable ingredients, commercially affordable, stable throughout shelf life and enjoyable to eat. Each of these objectives influences formulation decisions as improvements in one area can create compromises elsewhere. Protein innovation is therefore less about higher protein content but more about solving the formulation challenges in a final product.

Complete ingredient systems

As a result, the food and beverage industry is moving away from individual ingredients and towards complete ingredient systems and formulation expertise.

Success depends on understanding how proteins interact with fibres, starches, hydrocolloids, enzymes, flavour systems and processing conditions to achieve both nutritional and sensory objectives.

The aim is to integrate protein so effectively that consumers barely notice its presence. This requires technical expertise throughout the supply chain as manufacturers look to partners that can solve formulation challenges rather than simply supplying ingredients. Future innovation will rely on advanced solutions for texture optimisation, flavour modulation, moisture management, process efficiency and shelf-life performance.

Here, high-quality ingredient suppliers such as IFF and GoodMills Innovation play an important role, offering significant application expertise and ingredient technologies to overcome sensory and technical hurdles associated with protein fortification. Whether through texture systems, flavour solutions, functional cereal ingredients or application-specific formulation support, the objective is the same: higher nutritional performance without compromising consumer acceptance.

Connecting manufacturing & formulation expertise

For ACI Group, this is changing how value is delivered to customers. Access to ingredients remains essential, but so is the ability to connect manufacturers with technical expertise, formulation support and application knowledge. To create a competitive advantage, manufacturers need partners to steer them through the growing complexity of higher nutritional ambitions.

Recent developments in the protein market appear less like signs of slowing demand and more like evidence of a category reaching maturity. The challenge is delivering protein in ways that feel effortless, enjoyable and seamlessly integrated into everyday eating occasions.

The brands that succeed will be those that deliver better nutrition while maintaining the taste and texture consumers already enjoy. Achieving that balance requires more than ingredients alone. It requires formulation expertise.
