"A study at the University of Applied Sciences Northwestern Switzerland (FHNW) recently aimed to evaluate the environmental impact of burger patty production. A patty made with proteins sourced from brewer’s spent yeast (BSY) was compared with conventional beef and a vegan one as benchmarks. The ISO 14040 ff Life Cycle Assessment (LCA) showed that Yeastup's Yeastin can reduce the environmental footprint of a 113-g. burger patty by 74-81% depending on the indicator examined. With a neutral taste, Yeastin’s nutritional profile matches that of animal proteins. Formulations containing the ingredient may show promising functional properties in laboratory scale trials."
