Exploring the Gluten-Free Market: Pasta and Flours

From dietary necessity to cereal innovation platform

Gluten-free foods are often discussed as if they belonged to a single, clearly defined market. In reality, they sit at the intersection of medicine, nutrition, cereal technology, consumer perception, industrial safety and product innovation. For people with coeliac disease, gluten-free products remain a strict dietary necessity. For many other consumers, however, they have become part of a wider set of lifestyle choices, often associated with lightness, wellbeing and perceived health benefits.

This double identity creates one of the most interesting tensions in today’s food industry. Gluten-free products must first be safe for people who cannot tolerate gluten, but they must also compete in mainstream retail with the same expectations applied to conventional foods: good taste, proper texture, convenience, clean labels, reasonable shelf life, attractive positioning and, increasingly, better nutritional value.

The FoodTech Village webinar Exploring the Gluten-Free Market: Pasta and Flours addressed this complexity by bringing together nutritional science, industrial production experience and process engineering. Moderated by Prof. Sebastiano Porretta, the session explored why gluten-free foods are not simply “wheat-free” versions of familiar products, but technologically demanding systems that require a complete rethinking of ingredients, structure and process.

The webinar moved through several complementary perspectives. Prof. Daniela Martini, from the University of Milan, examined the nutritional quality of formulated gluten-free products and challenged the widespread assumption that gluten-free automatically means healthier. La Veronese presented the market, safety and raw-material challenges behind gluten-free flours. GustaMente offered an example of gluten-free pasta innovation without gums. Anselmo Group then focused on the industrial technologies that make gluten-free pasta possible, with particular attention to starch gelatinisation and process control.

Taken together, the discussion showed that gluten-free is no longer a niche. It has become one of the most advanced testing grounds for innovation in cereal-based foods.

The first distinction: naturally gluten-free foods and formulated gluten-free products

A key point made early in the webinar was the need to distinguish between naturally gluten-free foods and formulated gluten-free products.

Naturally gluten-free foods — such as rice, corn, legumes, potatoes, fruits, vegetables, meat, fish and many dairy products — can clearly be part of a balanced diet. The technical and nutritional challenge discussed in the webinar, however, concerns formulated gluten-free products: pasta, bread, flours, mixes, bakery products, snacks and other processed foods designed to replace conventional cereal-based products.

This distinction matters because the nutritional value of a gluten-free diet depends not only on the absence of gluten, but on what replaces it. A product may be gluten-free and still be poor in fibre, low in protein, rich in refined starches or less favourable in terms of micronutrients. Conversely, a well-designed gluten-free product can become a vehicle for improved nutritional quality, especially when it includes legumes, whole grains, fibres or carefully selected raw materials.

The problem is not gluten removal itself. The problem is the replacement pattern.

Why gluten-free is not automatically healthier

Prof. Daniela Martini’s contribution was particularly important because it addressed one of the most persistent misunderstandings in the category: the health halo around gluten-free foods.

For people with coeliac disease, gluten-free products are not a matter of preference. Coeliac disease is an autoimmune disorder triggered by gluten ingestion in genetically predisposed individuals. Even small amounts of gluten can cause intestinal inflammation and damage, making a strict lifelong gluten-free diet the only effective treatment.

But gluten-free consumption extends far beyond the prevalence of diagnosed coeliac disease. In many countries, a significant number of households buy gluten-free products even when no one in the household has coeliac disease. Some consumers do so because of non-coeliac gluten sensitivity. Others are influenced by media narratives, social media, marketing messages or the belief that gluten-free foods help with weight loss, reduce inflammation or are generally healthier.

This is where the health halo becomes problematic. A positive claim on a label can lead consumers to generalise that positivity to the whole product. If something is gluten-free, organic or low calorie, it may be perceived as healthier regardless of its actual nutritional composition.

The evidence presented during the webinar pointed to a more nuanced reality. Some studies comparing gluten-free products with gluten-containing counterparts have found that gluten-free options can contain more sugar, more calories, more refined starches, less fibre or fewer micronutrients such as iron and B vitamins. This does not mean gluten-free foods are nutritionally inferior as a category. It means the category is highly variable.

A gluten-free pasta made from corn and rice does not have the same nutritional profile as a pasta made with legumes or enriched with fibres. A gluten-free bread based mainly on starches behaves differently from one formulated with whole grains or protein-rich ingredients. The product must be evaluated on its formulation, not on the gluten-free claim alone.

For the industry, this is both a warning and an opportunity. The market cannot rely indefinitely on perception. If gluten-free products are to become credible mainstream foods, their nutritional performance must increasingly support their positioning.

From substitution to nutritional strategy

The webinar repeatedly returned to one idea: gluten-free development should not be reduced to substitution.

Removing gluten means removing a complex viscoelastic network that is responsible for structure, elasticity, gas retention, cohesion and rheological performance in many cereal-based products. In bread, gluten helps create volume and structure. In pasta, it contributes to firmness, cooking resistance and texture. In bakery products, it affects dough handling, shelf life and sensory quality.

The traditional way to compensate for this absence has often involved refined starches, hydrocolloids, emulsifiers, fats and other functional ingredients. These tools can be useful and sometimes necessary, but they do not automatically produce a nutritionally balanced product. If gluten is replaced mainly with refined starch, the resulting food may be safe but not necessarily nutritionally equivalent.

Prof. Martini therefore proposed a more ambitious view: gluten-free formulation can become a nutritional opportunity. Instead of asking only how to reproduce the structure of wheat-based foods, companies can ask how to design gluten-free products that meet defined nutritional targets. This might involve legume flours, agri-food by-products, higher fibre levels, improved protein content or mathematical optimisation tools such as linear programming.

In this perspective, gluten-free innovation moves from technological compensation to food design. The question is no longer simply “How do we replace gluten?” but “What kind of food do we want to create?”

A market that has become industrially mature

La Veronese’s contribution placed the discussion in a market and manufacturing context.

The gluten-free sector has grown significantly and is expected to continue expanding. Italy is one of the most important European markets, supported by a high diagnosis rate of coeliac disease, a well-developed consumer culture and a strong relationship with pasta and cereal-based foods. Pasta remains a central segment, followed by flours, mixes, bread, baked goods, snacks and breakfast cereals.

The distribution landscape has also changed. Gluten-free products were once strongly associated with pharmacies, especially for medically diagnosed consumers. That channel remains important, particularly in Italy where vouchers support coeliac consumers. But gluten-free products are now fully present in supermarkets, food service, private-label programmes and e-commerce.

This mainstream visibility has changed expectations. A gluten-free product cannot be acceptable only because it is safe. It must also be good. It must be easy to use, taste-driven, consistent, recognisable and suitable for modern consumption habits. Gluten-free has shifted from “special food” to a segment of the food industry.

Yet this shift does not reduce the importance of safety. On the contrary, it increases the responsibility of producers, because broader distribution requires even more reliable supply chains, controls and communication.

Safety: the non-negotiable foundation

For gluten-free manufacturers, safety is not a marketing promise. It is the basis of trust.

A product can be defined as gluten-free only if it contains less than 20 parts per million of gluten. This threshold leaves no room for approximate management. For a person with coeliac disease, contamination is not a minor inconvenience; it can trigger an autoimmune reaction and cause serious intestinal consequences.

La Veronese presented this responsibility as a full supply-chain commitment. It begins with qualified and audited suppliers and continues through traceability from field to finished product. Dedicated facilities, raw-material testing, critical control points and finished-product analysis are all part of the process.

The company described the use of ELISA testing as a recognised reference method for gluten determination. Certifications such as BRC are important, but the presentation correctly framed certification as a daily commitment rather than a final achievement. Procedures must be maintained, operators must be trained, audits must be repeated and risks must be understood at every stage.

The most interesting part of this message was cultural. Food safety management is often viewed as a cost, but in the gluten-free market it is the foundation of credibility. Without trust, the category cannot exist.

Gluten-free cereals: not all raw materials behave the same way

The discussion then moved to the raw materials used in gluten-free flours and products. One of the clearest messages was that gluten-free cereals and pseudocereals differ widely in function, nutrition, cost and risk profile.

Rice remains one of the most widely used gluten-free cereals because of its versatility, neutral flavour and broad applicability. Corn offers distinctive flavour and binding properties and remains highly relevant in pasta. Buckwheat is appreciated for its protein content and strong sensory identity. Millet was described as underutilised but potentially interesting for its mild flavour, fibre and protein. Teff and quinoa are more challenging industrially and often positioned as premium ingredients, although local European production could create new opportunities. Oat is familiar to consumers and valued for fibre, especially in beverages, but it raises contamination concerns and may not be suitable for all sensitive consumers because of specific protein fractions.

This variety shows why gluten-free formulation cannot depend on a universal recipe. Each raw material has its own hydration behaviour, flavour profile, processing response, nutritional composition and cost structure. Choosing a cereal is not only a matter of replacing wheat; it is a strategic decision that affects the whole product.

Nickel: an emerging variable in gluten-free formulation

One of the most specific and technically interesting topics addressed by La Veronese was nickel.

Nickel sensitivity and allergy are increasingly relevant, not only through skin contact but also through dietary exposure. For consumers who are both coeliac and nickel-sensitive, dietary restrictions can become particularly difficult. Some gluten-free cereals may accumulate significant nickel levels, turning raw-material choice into a new safety and quality consideration.

The presentation compared several gluten-free cereals in terms of nickel content, noting higher levels in ingredients such as buckwheat and oat, moderate levels in corn and rice, and very low levels in the sorghum varieties used in the company’s controlled supply chain.

This is an important development because it shows how gluten-free innovation is expanding beyond the original gluten question. Future products may need to respond to multiple sensitivities, contaminant concerns and dietary constraints. In this context, raw-material control becomes a competitive advantage.

Sorghum as a possible game changer

Sorghum emerged as one of the most promising raw materials discussed during the webinar.

It is one of the most cultivated cereals globally and a staple for millions of people, especially in Africa and Asia. It is also increasingly cultivated in Europe and Italy. From an agricultural point of view, sorghum is attractive because of its adaptability and resilience. From a gluten-free point of view, it offers potential in nutrition, sustainability and low nickel content.

La Veronese presented sorghum not as an exotic addition, but as a strategic platform. The company described work on a dedicated supply chain and patented processes, including the ability to produce pasta with only sorghum and water, without binders, as well as additive-free mixes.

This is significant because it addresses several market demands at once: gluten-free safety, clean label, nutritional improvement, agricultural sustainability and ingredient transparency. If the sector can develop products that rely less on additives and more on controlled raw-material functionality, gluten-free foods may move from compensation to genuine innovation.

Innovating tradition without gums

The short intervention by Oriana Pollio of GustaMente added an entrepreneurial example to the discussion. The company produces ambient gluten-free pasta with a process designed to remove as much water as possible and achieve a shelf life of six months. Its positioning focuses on gluten-free pasta without gums such as guar or xanthan.

This point is relevant because it reflects a wider market direction. Gums and hydrocolloids have played an important role in gluten-free development, and they remain useful tools. But many consumers increasingly prefer shorter ingredient lists and formulations that appear closer to traditional foods.

The challenge is that gluten-free products often need structural support. Creating pasta without gums requires process know-how, controlled formulation and dedicated production. This example shows that clean-label gluten-free innovation is not about removing functional ingredients casually. It is about finding alternative ways to deliver structure, shelf life and sensory quality.

Why pasta is one of the toughest tests

Biagio Sala of Anselmo Group brought the webinar into the field of process engineering, focusing on gluten-free pasta.

His central point was simple: there is not one technology for gluten-free pasta. There is one technological route for each recipe.

In conventional pasta, gluten helps bind starch granules and contributes to structure. Without gluten, pasta cannot be produced successfully unless the raw material is transformed in a way that creates an alternative structure. Early gluten-free pasta often performed poorly during cooking, releasing starch, becoming sticky and losing firmness. The advances of the last twenty-five years have been made possible by better ingredients and more precise technologies.

Sala also placed gluten-free pasta in a historical context. Rice-based pasta has existed in Asia for a very long time, but the industrial development of gluten-free pasta for coeliac consumers followed the scientific understanding of the relationship between gluten and coeliac disease. For many years, gluten-free pasta was treated as a special medical product. A turning point came when large brands entered the category and brought gluten-free pasta into mainstream supermarkets. At that point, quality expectations changed.

Today, gluten-free pasta can also be used as a nutritional carrier. Instead of focusing only on the absence of gluten, manufacturers can use pasta to deliver proteins, fibres and other nutritional benefits. This matches the broader shift from medical substitution to mainstream food design.

Gelatinisation: the core of gluten-free pasta technology

The most important technical concept in Sala’s presentation was starch gelatinisation.

Without gluten, the structure of pasta must be created by transforming starch. Under heat and hydration, starch granules swell, lose their crystalline structure and form a matrix capable of supporting the pasta shape. Once processed and dried, this structure allows the product to behave properly during cooking.

There are two main industrial routes.

The first uses pre-gelatinised ingredients. In this case, specialised suppliers treat the flour before it reaches the pasta producer. The producer can then hydrate, mix, knead and extrude it using equipment similar to conventional pasta lines. This route is relatively simple, but it has drawbacks: higher ingredient cost and less direct control over the gelatinisation degree.

The second route starts from native flours and performs gelatinisation inside the pasta production process. For easier raw materials such as corn and rice, steam treatment in an additional mixer may be enough. For more difficult ingredients such as legumes, which contain more protein and fibre, higher temperatures and more advanced systems are required. Cooker-extruders, including twin-screw systems with heated jackets, can reach internal temperatures above those possible with steam alone, allowing better management of complex raw materials.

This distinction is critical. A rice-corn pasta, a chickpea pasta, a lentil pasta and a sorghum pasta cannot be treated as the same product. Each matrix requires its own process conditions.

Gluten-free pasta as a nutritional vehicle

The comparison between traditional semolina pasta, whole wheat pasta, standard gluten-free pasta and legume-based gluten-free pasta showed how different the category can be.

A standard corn-rice gluten-free pasta may have higher carbohydrate content and lower protein density than semolina pasta. But a legume-based pasta can offer much higher levels of protein and fibre. Energy values may not differ dramatically, but the nutritional quality can change substantially.

This confirms the argument made by Prof. Martini: gluten-free products are not inherently better or worse. They depend on formulation.

The opportunity for pasta manufacturers is therefore clear. Gluten-free pasta can become a carrier for nutrition, not just a replacement for semolina. It can help increase legume consumption, improve fibre intake and create new value propositions for consumers who want healthier, more functional foods.

Conclusion: gluten-free as a design discipline

The webinar showed that gluten-free foods should not be understood as a simplified category. They are among the most complex products in the cereal-based industry.

They require medical reliability, nutritional awareness, raw-material expertise, process engineering, sensory quality and transparent communication. They must be safe for coeliac consumers, credible for mainstream consumers and technically robust for industrial production.

The next phase of the gluten-free market will depend on the ability to move beyond substitution. The goal is not merely to produce bread, pasta and flours without gluten. The goal is to design foods that are safe, nutritionally coherent, enjoyable and aligned with modern expectations around clean label and sustainability.

Gluten-free innovation begins with a constraint, but it does not have to end there. When supported by science, careful formulation and advanced processing, that constraint can become a platform for better food design.
