EIT Food identifies barriers to precision fermentation adoption

EIT Food has published research examining how consumers respond to precision-fermented food ingredients, finding that curiosity about the technology is accompanied by questions concerning safety, authenticity and the characteristics of finished products.

The Consumer Observatory report, From Curiosity to Confidence: Developing effective messaging for products made with precision fermentation, identifies taste, texture and nutritional value as important factors in consumer acceptance. It also recommends clear explanations of how ingredients are produced rather than relying on broad claims about innovation or sustainability.

Published on 14 October 2026, the qualitative study involved 45 participants who explored their perceptions of precision fermentation before examining product concepts and communication approaches in three groups. The findings describe attitudes and reasoning within that research group, rather than providing a statistically representative measurement of European purchasing intentions.

Precision fermentation uses selected microorganisms, such as yeast or fungi, to produce specific substances under controlled manufacturing conditions. Depending on the biological system, the resulting ingredients can include proteins, fats and other compounds used to provide nutritional or functional properties in finished foods.

The process differs from conventional fermentation in which microorganisms transform an existing food substrate, as occurs in many traditional fermented products. Precision fermentation can instead use a microorganism as a production system for a defined ingredient, which is subsequently recovered from the fermentation mixture.

Following cultivation, the target substance may need to be separated, purified, concentrated and dried before it can be supplied to food manufacturers. The specific processing requirements depend on the organism, the compound being produced and the quality specifications required for the intended application.

Those manufacturing stages help explain some of the questions identified by the Consumer Observatory. Participants were uncertain about the role of microorganisms, the relationship between the process and conventional food production, and whether the resulting ingredients should be regarded as familiar foods or alternatives.

Some also expressed concerns about potential consequences for traditional farming and employment. These responses show that perceptions of a new food technology can be influenced by the wider production system as well as the characteristics of the product a consumer is considering.

The study found that many participants were willing to try products made using precision fermentation before forming a settled opinion. Interest in the technology was therefore present even among people who had reservations about the process or lacked detailed knowledge of how it works.

That willingness creates a particular requirement for product development because the first eating experience can influence whether curiosity develops into repeat purchasing. A consumer who is interested in the manufacturing technology may still reject a product if its taste, texture or other characteristics fail to meet expectations.

EIT Food identified an additional difficulty in explaining the process. Descriptions that were too vague sometimes made the technology appear less credible, suggesting to participants that important information might be missing.

Detailed scientific descriptions can present a different problem if they introduce unfamiliar terminology without establishing what the process produces or why the ingredient is used. The research therefore supports explanations that preserve technical accuracy while connecting the manufacturing method with properties that can be understood in the finished food.

Traditional fermentation provided a useful point of comparison. Participants recognised products such as bread, yoghurt and cheese, although some had not previously considered the role of fermentation in their manufacture.

Relating precision fermentation to those familiar examples helped some participants understand the concept, but the processes are not interchangeable. A microorganism producing a purified target protein presents different manufacturing and product characteristics from a fermented food in which microbial activity changes the composition of the original material.

Accurate explanations must therefore account for what is produced, whether the organism or its components remain in the ingredient, and how the recovered material is incorporated into the finished food. These details depend on the particular process and cannot be generalised across every precision fermentation application.

The research also found that product benefits associated with direct experience were more compelling than broader messages about environmental or ethical advantages. Taste, texture and nutritional value were prominent considerations, while sustainability and animal welfare generally acted as supporting reasons rather than the decisive factors in product choice.

These preferences connect with the technical work required during formulation. An ingredient may meet its analytical specification but behave differently from a conventional alternative when combined with other components or exposed to the conditions used during food manufacture.

Proteins, for example, can influence gel formation, viscosity, foaming and emulsification, depending on their molecular characteristics and the surrounding formulation. Achieving a specified protein content does not independently establish that a product will possess the intended mouthfeel or processing behaviour.

Heating, acidity, mechanical shear and interactions with salts, fats and other ingredients can alter those properties. Manufacturers therefore need to establish how a fermentation-derived ingredient performs under the conditions used to produce the intended food.

A dairy-style beverage may require a protein that remains stable during homogenisation and thermal processing, while another application could depend on a controlled increase in viscosity or gel strength. The same ingredient may consequently offer different advantages and limitations across product categories.

Downstream recovery is also relevant to consistency. A protein produced during fermentation must be separated from the process mixture and supplied at a specification that supports predictable use by the customer. Variations in recovery, purification or drying can influence manufacturing yield and the characteristics of the material available for formulation.

Where a new ingredient is intended to reproduce a familiar food characteristic, sensory testing is needed alongside analytical and functional measurements. The chemical composition of an ingredient cannot by itself predict the complete eating experience of a formulated product.

The Consumer Observatory cautions against presenting new products solely as replacements for established foods. Such positioning can encourage consumers to compare unfamiliar formulations directly with products whose flavour, texture and other characteristics they already know.

An ingredient offering a distinct functional or nutritional benefit may be better suited to a product developed around that characteristic, provided the benefit is supported by evidence and delivered consistently in the finished formulation.

Regulatory requirements remain separate from consumer acceptance. The status of a precision-fermented ingredient depends on the organism, production process, composition and destination market, with appropriate food safety assessment, authorisation and labelling obligations applying where required.

The study does not establish that consumers regard all precision-fermented ingredients as safe or that a particular formulation will achieve commercial acceptance. Its sample is qualitative, and the responses cannot be used to calculate population-wide demand or purchasing rates.

Nevertheless, the findings identify a close relationship between technical product development and the information used to introduce the resulting food. Commercial acceptance will require reliable ingredient manufacturing, appropriate regulatory compliance and finished products that deliver the sensory and nutritional characteristics described to consumers.
