Consumer Acceptance of Alternative Proteins: A Systematic Review of Current Alternative Protein Sources and Interventions Adapted to Increase Their Acceptability

Conventional meat consumption has triggered an environmental burden along with effects on different disease spectrums according to existing research. The dietary patterns adopted by consumers significantly impact both planetary and individual health. Interventions are needed to support the protein transition. However, there is not yet an overview of interventions towards acceptance of novel proteins available. This systemic review highlights different varieties of alternative proteins and interventions adopted to increase the acceptance of alternative protein sources. Educational intervention, persuasion, training, and modeling approaches are summarized in this review. Furthermore, behavioral models triggering the consumer’s response towards different alternative proteins are also discussed. The systemic review highlights that consumer acceptance varies among different alternative proteins. Food choice motives, familiarity, food neophobia, disgust, and cultural norms are among the various drivers of consumer acceptance. A comparison of these drivers indicates inconsistencies, presenting the need for future research.
