Food innovations offering new sources of protein as well as new urban food production aims to provide solutions for food production under restricted resources. The alternative protein sources and urban agriculture are not part of the daily lives in Germany. Involving the public in research on food innovations not only helps to increase consumer acceptance (Tuorila and Hartmann, 2020) but also can facilitate more responsible research and innovation. To date, only few studies have investigated consumer acceptance of new food solutions in Germany (Weinrich and Elshiewy, 2019) and little is known about the consumers’ perceptions of innovations with longer time horizons. Therefore, the present study investigates the public perceptions of selected food innovations (algae, crickets, halophytes, jellyfish) and urban food production in Germany.
