Critical food and nutrition science challenges for plant-based meat alternative products.

A reduced reliance on animal-based diets with a move towards a more plant-based diet has driven the market demand for new generation sustainable plant-based meat alternatives. This review covers science and business perspectives relating to the development of plant-based meat alternatives. A conceptual framework to help inform the innovation pathway is provided. The market opportunity, consumer perspectives, the science that underpins the development of plant-based meat alternatives and patent information relating to these products are discussed. Careful navigation through the public domain science literature and patent landscape is necessary for informing the choice of ingredients, formulations and processes for producing plant-based meat alternatives. Attention to design of ingredient systems for optimization of flavor, texture, binding, color and nutrition is necessary for development of plant-based meat alternatives with desirable consumer attributes. Recommendations for further research for developing superior formulations for consumer-acceptable plant-based meat alternative products for improving sustainability outcomes are suggested.
