                                Solein is a revolutionary food ingredient made from a naturally occurring, single-cell microbe that feeds on carbon dioxide and hydrogen, a groundbreaking process developed by Finnish company Solar Foods. This protein-rich powder offers a genuinely sustainable alternative to traditional protein sources, requiring only minimal land and water for production.
