Sustainability of Key Proteins in Plant-Based Meat Analogs Production: A Worldwide Perspective

The market for plant-based analogs for meat is growing exponentially. In addition to motivations related to the search for health benefits, the consumption of such products is justified by the sustainability of their production since the use of non-renewable resources and the emission of polluting gases is lower than their animal-origin equivalents. However, little information regarding the global panorama of the sustainability of plant-based meat analogues is available, mainly due to the diffuse distribution of food matrices used across the planet. In this sense, this narrative review aimed to describe the state of the art regarding the use of resources and sustainability of the inputs used as protein sources in the manufacture of plant-based meat analogues. From the review carried out, it was possible to observe that the biggest problem in producing these plant-based alternatives lies in using inputs that are not native to the countries where the products are marketed, especially in the case of South American countries. Ingredients widely used in the production of these analogues find better cultivation conditions in the northern hemisphere, as in the case of lentils, peas and chickpeas; thus, South American markets depend on imports, reducing the sustainability of the products.
