Key takeaways:
- As the definition of ‘healthy’ shifts from reduction to positive nutrition, snacks must now deliver fibre, protein and functionality without sacrificing enjoyment.
- Texture, flavour intensity and multi-sensory experiences are becoming critical tools to compensate for reduced sugar, salt and fat.
- Repeat purchase depends less on health claims and more on whether products deliver a satisfying, indulgent eating experience.
The definition of ‘healthy’ is no longer what it once was. Where the category was historically shaped by reduction – less sugar, less salt, less fat – it’s now being driven by addition, experience and expectation. Fibre, protein and plant-based ingredients are part of the equation, but so too is how a product feels, tastes and satisfies.
That shift is creating a more complex challenge for manufacturers. Reformulation alone is no longer enough to secure repeat purchase. Consumers may be drawn in by on-pack claims, but they still expect snacks to deliver the same comfort and enjoyment as their more indulgent counterparts.
“Customers are looking for healthier snack without compromising taste and comfort,” explains Lydia Bouchoul, flavourist and seasonings technical leader for Sensient Europe. “Sugar, salt, fat have been knowns and used since old time for their enhancing properties. They are ingredients that traditionally drive taste and satisfaction.”
Removing or reducing those ingredients therefore creates a gap that has to be filled elsewhere. “Sensory design is becoming a key differentiator in healthier snack and bakery products,” she adds. “Beyond flavours, element such as sensation, texture, visual appeal and even sound are being strategically improved to deliver a more holistic eating experience.”
Sensory design fills the reformulation gap
As traditional taste drivers are dialled down, texture is stepping in as one of the most effective ways to rebuild satisfaction. It’s no longer a byproduct of formulation but a deliberate design tool.
“Texture is one of the main examples. Crunchiness can enhance and compensate for salt and sugar reduction. How a crisp or a puffed snack breaks down in the mouth can impact satiety,” says Bouchoul.
Even the acoustic experience matters. “Even sound, such as how the product is crunching can reinforce freshness and enjoyment.” These sensory cues play into perception, helping products feel more indulgent than their nutritional profile might suggest.
At the same time, ingredient choices are evolving. “Cereal-based snack moves beyond traditional corn or wheat to create healthier more functional product,” she explains. “It is important, because it not only drives nutrition but also texture, structure and overall eating experience.”
Wholegrains and multigrains are increasingly used to deliver fibre and complexity, while alternative bases are gaining traction. “Ancient grains such as quinoa, millet are gaining popularity in puffed snack or extruded offering lightness and crunch while improving nutrition. Pulses and legume flours bring a strong crispness when extruded helping to compensate for reduced fat.”
However, these ingredients introduce new sensory challenges. “They can also sometime bring challenging taste profile such as bitterness, earthiness or astringency,” notes Bouchoul. “Without an impactful seasoning these attributes can limit consumer acceptance.”
That puts renewed emphasis on flavour. “Consumer may be initially attracted by health claims such as ‘high protein’ or ‘wholegrain’, but they will only buy again if the product delivers an enjoyable eating experience.”
Flavour intensity and sensation drive engagement
If healthier snacks are to compete, they need to do more than just taste good – they need to excite. That is pushing brands towards bolder, more layered flavour profiles.
“Better-for-you snack is no longer about just being healthy, it also combining trendy and taste innovation,” says Bouchoul. “Brands are also looking after more bold flavours, like swicy, spicy, swangy. Spicy trend is still very present, for example, we can see in the latest launches ‘chili and lime’, ‘hot honey’, ‘spicy Buffalo’.”
But flavour alone is no longer the full story. Consumers are looking for more immersive experiences that go beyond taste.
“Consumers today are constantly looking to be surprised, challenged, and engaged through their food experience. Curiosity is a strong driver of choice especially in snacking category. One of the emerging trends is the concept of 360° sensory experience, where taste is only one part of a much broader, immersive journey.”
That includes both texture and physical sensation. “Consumers are no longer satisfied with ‘just’ a flavour, they are seeking for elevated, multidimensional experiences that stimulate several senses at once. This includes texture (extra crunchiness) and even physical sensations such as heating, cooling, tingling.”
These elements can transform otherwise familiar products. “For example, imagine eating a barbecue flavoured crisps and experiencing not only the smoky taste but also a subtle warming sensation that evokes the heat of a grill. Or a mojito flavoured snack that deliver refreshing cooling effect, reminiscent of fresh mint.”
This added dimension is particularly valuable for the BFY category. “As better-for-you products can sometime be perceived as less indulgent, enhancing them with exciting texture, sensation, helps bridge the gap between health and enjoyment.”
Technology and formulation redefine what ‘healthy’ delivers
Delivering on these expectations increasingly depends on flavour technology. As formulations become more complex, manufacturers are relying on targeted tools to maintain balance and appeal.
“Consumers are seeking for healthier snacking options,” says Bouchoul. “They want to indulge without compromising their wellbeing but still expect a flavourful satisfying and even indulgent eating experience.”
To achieve this, a range of solutions is being deployed. “Solutions including salt booster, mouthfeel enhancer, umami booster and sugar booster will help enhancing taste perception, improve overall balance, enabling reduction in salt, sugar and fat without compromising enjoyment.”
At the same time, masking technologies are addressing the downsides of new ingredients. “These new bases can introduce taste challenges like bitterness and earthy notes,” she says. “A range of natural flavours can mask different attribute like bitterness, metallic, astringency.”
Regulation is also accelerating the pace of change. “Governments are implementing stricter regulations and taxes on products high in sugar, fat and salt, accelerating the need for reformulation across the food industry.”
All of this feeds into a broader shift in how health is defined. “It is no longer just about reducing sugar, fat and salt, but also about incorporating more positive ingredients such as protein, fibre, whole grain, and plant-based components. The next wave of innovation in healthy snacking is going to be less about ‘better-for-you’ ingredients on their own but more about creating a full sensory experience.”
