Vegan spread applications of alternative protein from torula yeast: product development and consumer perception
Alternative protein sources are gaining attraction in food industry and consumers. Proteins obtained by single-cell organisms, such as torula yeast, are of enormous interest, as they are highly scalable, efficient, and sustainable, and the production costs are comparably low. Nevertheless, proteins...

Alternative protein sources are gaining attraction in food industry and consumers. Proteins obtained by single-cell organisms, such as torula yeast, are of enormous interest, as they are highly scalable, efficient, and sustainable, and the production costs are comparably low. Nevertheless, proteins obtained from yeasts are still mostly known and studied for feed applications, despite their nutritional, functional, and sensory benefits for various food applications. Testing consumer acceptance of products, especially products containing alternative proteins provides insights into, e.g., market success, consumer perception, and optimization potential. In this study, the development of two vegan spread powders, high in protein and containing torula yeast as an alternative protein source, is introduced. The result of food product development using torula yeast were “Leberwurst”-style (14.7% protein) and a “Balkan”-style (9.7% protein) spreads both meeting the criteria “at least 20% kcal from proteins of total product kcal” and thus claimable as “high-protein.” The application of the alternative protein from torula yeast within the final products was studied by a consumer acceptance test (n = 123) within three different countries (Germany, Iceland, and Sweden).
