A recent survey conducted in four European countries focused on consumer acceptance of various protein sources for meat alternatives. Plant-based options like potato, rice, and peas were most accepted, likely due to their familiarity in the European diet. Regional differences were also observed, with oats being well-accepted in Finland, lentils in Italy, and almonds in Germany and Serbia, reflecting local culinary traditions and exposure. However, some plant-based sources like rapeseed, sunflower, and soy were less favored, likely due to negative taste perceptions and associations.

In contrast, alternative protein sources like algae, cultivated meat, and insects were met with lower expectations across all countries. Consumers perceived algae as healthier and more environmentally friendly, but had low taste expectations, while cultivated beef was seen as more favorable in taste but less healthy and sustainable. Overall, the study suggests that product developers and marketers should strategically select and label protein sources already accepted by consumers to enhance the appeal of meat alternatives and encourage wider acceptance among consumers.
