TNA Solutions has published an overview of the structural shifts redefining the global savoury snacks category, highlighting the pressures that are now reshaping both product development and capital investment across processing and packaging lines.

The company notes that consumer expectations have changed profoundly over the past decade. While indulgence once dominated the category, growth increasingly comes from products positioned around wellness, transparency and sustainability. According to figures referenced by TNA, the savoury snacks market reached USD 205 billion in 2024, with annual growth projected at around five percent through 2029. More than 60 percent of consumers report replacing meals with snacks, while healthy snack segments continue to outpace the broader market.

Against this backdrop, TNA identifies five areas exerting the strongest influence on manufacturers’ technical strategies: demand for functional better-for-you products, the acceleration of plant-based snacking, stricter control of acrylamide and trans fats, operational sustainability, and the increasing complexity of flavour delivery.

Functional Formulations Reshape Processing Requirements

The company points to a clear shift in the role snacks play in consumers’ daily routines. Segments positioned as better-for-you are expanding significantly, driven by formulations containing protein isolates, fibres, seeds, pulses and fruit-based ingredients. These inputs behave differently during frying, seasoning and packaging, requiring equipment that can handle delicate or oil-sensitive materials without compromising throughput.

Traditional lines designed for potato- or corn-based products may no longer be sufficient for these evolving formulations, increasing the need for adaptable slicing, cooking and flavouring technologies.

Plant-Based Inputs Increase The Need For Line Flexibility

Plant-forward snacking continues to broaden, fuelled by the rise of vegan, vegetarian and flexitarian consumers. TNA highlights forecasts indicating robust expansion of the plant-based snack category through the next decade.

From a production standpoint, plant-derived raw materials—often starch-heavy, high-moisture or irregular in shape—require consistent control in slicing, dewatering, frying and conveying. Manufacturers seeking to run multiple bases on a single line must therefore prioritise installation of highly adjustable systems capable of maintaining quality across a diverse input range.

Managing Acrylamide And Oil Quality Becomes Central To Compliance

Heightened regulatory attention on acrylamide and trans fats is prompting a re-evaluation of frying regimes. TNA cites technologies such as low-temperature finish frying, vacuum frying and pulsed electric field (PEF) treatment as increasingly important tools for reducing acrylamide formation and improving oil uptake profiles.

The company references multi-zone systems, blanching and vacuum-frying technologies—together with integrated oil filtration and defatting—as examples of equipment architectures capable of controlling temperature, pressure and oil quality more precisely.

Sustainability Targets Drive Adoption Of Low-Footprint Systems

Sustainability has progressed from a brand differentiator to an operational requirement, with retailers imposing ambitious carbon and packaging-reduction targets. TNA identifies several areas of manufacturer investment, including energy recovery systems, smaller oil volumes for faster turnover, water-reclaim systems and frying solutions engineered for reduced footprint.

The company also notes that the push toward recyclable formats and digital traceability requires packaging systems compatible with thinner films and integrated data management.

Strong Flavour Profiles Demand Tighter Seasoning Precision

As flavour innovation accelerates, manufacturers increasingly rely on precise seasoning control. TNA highlights gravimetric on-machine seasoning technologies and controlled conveying systems as essential for maintaining consistency, particularly in products with layered flavour profiles or fragile structures.

Integrated Line Design Gains Importance

Across all five trends, TNA emphasises that isolated equipment upgrades are no longer sufficient. Instead, producers are turning toward end-to-end line integration that links raw material reception, frying, seasoning, distribution, primary and secondary packaging, and digital automation into a unified system.

The company outlines its own framework, which spans flexible slicing, multi-zone frying, rapid-changeover seasoning and vertically integrated packaging platforms. Technologies such as its vertical form-fill-seal system and automated film-splicing functions are positioned as tools to reduce downtime and material waste.

Case Study: Benestar Brands’ Integrated Line Overhaul

TNA cites Benestar Brands, a US-based producer of pork rinds and cracklings, as an example of integrated design in practice. Facing rising energy costs and stricter sustainability requirements, the company adopted a complete TNA line covering frying, seasoning and packaging.

At the centre of the upgrade was a high-performance batch fryer that reduced oil use, supported energy-efficient heating and helped cut product rejects to below three percent. Integrated oil filtration extended oil life and stabilised product quality. Seasoning precision and packaging flexibility were addressed through TNA’s on-machine seasoning system and vertical form-fill-seal platform, enabling Benestar to pack multiple formats on a single line.

According to TNA, the outcome included quality improvements, reduced environmental impact and a shorter return-on-investment period, supported by remote assistance and operator training.

Looking Toward 2026

TNA expects the pressures shaping the market to intensify in 2026. Portion-controlled formats are forecast to grow as consumers regulate calorie intake, while retailers are expected to raise expectations on clean labelling and packaging recyclability. With snacking continuing to displace traditional meals, efficiency, flexibility and sustainability will become central to competitive performance.

The company positions integrated production lines as a means to help manufacturers align with these pressures while supporting future product development cycles.
