Despite growing environmental awareness, consumers still prioritize sensory experience when making food choices. Sensory satisfaction—taste, texture, aroma—plays a crucial role in consumer acceptance of sustainable products. Even when consumers are motivated by environmental concerns, if a product doesn’t deliver on sensory quality, they are unlikely to repurchase. Any deviation in flavor, texture, or aroma in a new, sustainable product can result in rejection. R&D teams use sensory science to carefully balance sustainability with sensory quality, ensuring that consumers don’t perceive a compromise when switching to a more eco-friendly option. This balance is essential because even the most sustainable product will fail in the market if consumers are dissatisfied with how it tastes or feels.

A clear example is cultured, or lab-grown, meat. Despite its benefits for animal welfare and the environment, consumer acceptance remains limited due to doubts about its flavor and texture. A study in Italy showed that while positive information about cultured meat’s safety and nutrition increased willingness to pay, it did little to change perceptions of its flavor. This indicates that, regardless of sustainability, sensory concerns are often the deciding factor for consumers.

This is where sensory science becomes essential. For new sustainable products like cultured meat to succeed, they must match or exceed the sensory experience of traditional options. Without this, even the best sustainability messaging will struggle to overcome consumer hesitation.

Developing sustainable food products, particularly plant-based meat analogs (PBMAs), faces significant challenges related to flavor. As demand grows due to health, ethical, and environmental concerns, the market share of these products must increase to support sustainable food production. However, undesirable flavors often limit their acceptability.

Plant proteins frequently exhibit off-flavors, including beany, bitter, and astringent notes. A review of 276 articles identified key factors contributing to these undesirable tastes, such as volatile compounds and the effects of thermal extrusion cooking, a common method for creating meat-like textures.

The review also explored measurement techniques for flavor properties and strategies to reduce off-flavors and enhance sensory appeal. Addressing these flavor challenges is crucial for the success of plant-based alternatives.

R&D teams can leverage sensory science to refine formulations and processing methods, using flavor-masking strategies to improve the sensory experience of plant-based products. By tackling these flavor issues, sustainable alternatives can be both environmentally friendly and enjoyable, leading to greater consumer acceptance.

The growing demand for PBMAs is driven by environmental, health, and ethical concerns. However, replicating the sensory attributes of animal meat poses significant challenges. Recent innovations in PBMA ingredients and methodologies highlight advancements in texture, flavor, and nutritional profiles, showcasing the evolution from soy-based first-generation products to more diversified second- and third-generation options.

Key to mimicking the sensory experience of animal meat is the careful balance of proteins, polysaccharides, and fats. Research is increasingly focusing on new plant-based sources to enhance product quality and sensory appeal. While taste is a crucial factor influencing PBMA purchasing decisions, significant challenges remain in replicating the texture of animal-based meat, particularly as many PBMAs lack essential amino acids and micronutrients. Addressing anti-nutritional factors (ANFs) is vital for improving the nutritional profile of these products, ensuring they meet consumer expectations for both taste and health.

Production costs for PBMAs currently exceed those of traditional meats, impacting affordability and consumer adoption. However, advancements such as Feature-Augmented Principal Component Analysis are revolutionizing the modeling of the extrusion process, leading to enhanced equipment setup, parameter adjustments, and quality control. As production scales up and technologies improve, costs are expected to decrease, making PBMAs more accessible while also minimizing their environmental impact.

Despite the progress, continuous improvement in taste, texture, and nutritional value remains essential for fostering consumer acceptance. Effective marketing and educational campaigns can further enhance consumer awareness, emphasizing the benefits of PBMAs as a sustainable alternative to traditional meat. By addressing challenges like undesirable flavors and nutrient deficiencies, the industry can improve perceptions and contribute significantly to a sustainable food ecosystem. Balancing sensory quality with sustainability is not just an innovation challenge; it is a pathway to ensuring that plant-based alternatives become a staple in our diets, marrying the best of tradition with the demands of a sustainable future.

In conclusion, as the food industry shifts toward sustainability, the role of sensory science in developing plant-based meat alternatives cannot be overstated. Addressing consumer expectations for taste, texture, and nutritional value is essential for fostering acceptance and encouraging the adoption of sustainable choices. Through innovative approaches to ingredient sourcing, processing techniques, and flavor enhancement, R&D teams can create products that not only meet but exceed the sensory experiences associated with traditional meat.

The journey from innovation to tradition highlights the importance of balancing sensory quality with sustainability. While significant challenges remain, including production costs and the replication of meat-like textures, advances in technology and an increased understanding of consumer preferences offer promising pathways for improvement. By prioritizing sensory satisfaction and nutritional adequacy, the plant-based industry can effectively position itself as a viable alternative to conventional meat, appealing to a broader audience concerned with health, ethics, and environmental impact.

As the demand for sustainable food products continues to rise, ongoing research, effective marketing, and consumer education will be crucial in reshaping perceptions and driving the success of plant-based alternatives. Ultimately, by embracing sensory science as a key driver of innovation, we can create a more sustainable food ecosystem that satisfies both consumer desires and environmental needs, ensuring a healthier future for both people and the planet.

Parents understand that the maintenance of their child’s health and wellness is their responsibility; however, many parents face various challenges when trying to do so. FMCG Gurus findings highlight that sugar is the ingredient that parents are most conscious about in food and drink products, with 74% of consumers concerned by sugar content in products. As children are typically drawn to sugary indulgences, parents are concerned by the link between obesity and diabetes and the hidden sugars in products.

Many parents believe that the complex labeling used by brands disguises ingredients. As a result, brands should ensure that nutritional labeling is made clear and simple for parents so that they are able to unpick the nutritional profile of products within seconds.
