The snack market is evolving rapidly – and so are the demands placed on products. Alongside appearance, crunch and taste, consumers are paying increasing attention to ingredients, nutritional profiles and clear added value.

This is creating a market in which traditional snack attributes and current consumer trends are becoming increasingly intertwined. Taste and enjoyment remain key. At the same time, consumers are taking a closer look at ingredients and nutritional values. Demand is growing for plant-based ingredients, cleaner formulations and products designed for specific dietary needs – including high-fibre and gluten-free options, organic products and snacks with a higher protein content.

Protein in particular remains a major trend. Once primarily associated with sports nutrition, protein bars and shakes, it is now moving into a much broader range of food categories. Today, protein can be found in a wide variety of snack products – from plant-based savoury options to sweet applications.

Current market and trade show observations indicate that protein continues to gain importance in the snack segment. At international food industry exhibitions, protein-enriched concepts have been visible across a wide range of applications – not only in traditional fitness products, but also in savoury and sweet extruded snacks.

Trend data from Innova Market Insights points in the same direction: protein is one of the most sought-after ingredients in healthier snacks. More than one in three consumers actively look for products with a higher protein content in this context – while still expecting the qualities they traditionally associate with snacks.

And this is precisely where the challenge lies. Protein snacks still need to deliver the desired crunch, a pleasant mouthfeel and a well-balanced flavour profile, while also meeting the visual expectations of their respective category. Depending on the raw material base, increasing the protein content can affect not only the nutritional profile but also characteristics such as volume, colour, bite, surface texture and flavour.

The strength of a high-protein snack concept therefore lies not in its protein content alone, but in the interaction between formulation, raw materials, shape, texture, colour and seasoning. Only when these elements work together does a product have the potential to attract consumers at the shelf and deliver on expectations when eaten.

This is where extrusion technology offers a wide range of possibilities. Protein-rich snacks can be developed using pulses, cereals or plant-based protein sources, with variations not only in formulation but also in shape, texture and functional properties. A puff creates a different snacking experience from a wave, while a ring sets different expectations from a Soft Bite.

This makes it possible to translate the protein trend into a wide variety of food concepts: for example, an organic plant-based snack, a gluten-free option, an indulgent product with a familiar flavour profile, or a crunchy inclusion for bars, chocolate and other applications. The key question is always: what product idea should the concept deliver?

Protein-rich snacks are rarely created simply by adding another ingredient to an existing recipe. Formulation, processing technology and sensory properties are closely interconnected – which means even small adjustments can influence expansion, shape stability, surface characteristics or bite.

That is why the crucial work begins at an early stage. Which protein source best suits the desired product profile? What texture should the product have? What colour is required? Which flavour profile works well with the chosen raw materials? And what needs to be considered to ensure that an initial prototype can later be produced reliably on an industrial scale?

This is where Erbacher Food Intelligence brings its expertise to the table. We manufacture extruded snacks tailored to individual requirements – from formulation, shape and colour to functionality, flavour and application. Product development is not treated as an isolated formulation step, but as an integrated process combining raw material expertise, extrusion technology and industrial implementation. From the initial idea through to the market-ready product, we are a strong partner at every stage of development.

Customer-specific solutions from Erbacher Food Intelligence demonstrate just how diverse these concepts can be: examples include a high-fibre oat and date Soft Bite, a vegan soy and sunflower protein wave with paprika flavour and 26% protein, and a vegan, gluten-free lentil and sunflower protein puff with 20% protein and leek flavour in organic quality. These examples show how protein, plant-based raw materials, texture, flavour and product positioning can come together in very different snack concepts.

Erbacher Food Intelligence supports you on the journey to your ideal product – from the initial product idea and formulation development through to a tailor-made solution. In this way, snack trends become market-ready products that successfully combine enjoyment, functionality and industrial feasibility. Have an idea? Let's turn it into a successful food product together.
