Chapter 2: Consumer Perceptions of Food Proteins and Protein-enriched Foods

Protein ingredients are of great interest to consumers due to their nutritional value. Due to religious reasons and a rising concern about environmental impact, proteins from plants, algae, cultured meat, and edible insects are gaining interest. However, consumer acceptance of protein ingredients is hindered by off-flavors, undesirable textures and colors, and other cultural reasons. This chapter discusses the current knowledge on consumer acceptance of food protein ingredients, e.g., protein concentrate, isolate, and hydrolysate, and food protein-based and enhanced food products. Consumer acceptance from both survey studies and consumer sensory studies is included.
