Tasting the Future: Sensory Evaluation and Perception of Insect-Based Products Among GenZ and Millennials

Insect proteins are suitable for human consumption and hold potential in the foodservice sector, where there is growing pressure to reduce traditional meat consumption, and this alternative could be explored through innovative gastronomy landscapes, such as by incorporating insect-based proteins into gourmet dishes. This study uniquely explored how young adults—specifically GenZ and Millennials (aged 18–30)—perceived and accepted insect-based products and whether their dietary habits aligned with sustainable principles. A mixed-methods approach was applied, including a cross-sectional study related to attributes of participants on insect products and sensory evaluation of insect and commercial products, to investigate awareness, acceptance, and sensory experiences. Key barriers included food neophobia and cultural resistance. The findings revealed a significant gap between awareness and behaviour: while 86% recognised insects as nutritious and 58% associated them with sustainability, only 18.6% have tried consuming them. This is a notable larger disparity compared to the adoption of other sustainable alternatives, such as vegetable meat based on peas, which have seen broader acceptance in recent years. Additionally, although 93.2% found products more appealing when their natural appearance is hidden, traditional insect-free products were still rated higher in taste, sweetness, and texture. Some insect-based products such as protein bars showed potential for greater acceptance than others. Bridging the awareness-behaviour gap requires targeted education, sensory improvement, and strategic marketing to emphasise nutritional and environmental benefits. Chefs could play a vital role by designing innovative menus that incorporate these products in familiar forms. This is demonstrated by successful examples where chefs have normalised unconventional ingredients, such as seaweed, overcoming cultural barriers and enhancing acceptance. Future studies should focus on expanding the diversity of participants, mapping gender differences, considering and improving the sensory properties of more products, and confirming the bioavailability of insects to promote wider acceptance of insect consumption.
