ReToast is a story about trash to cash, determined to unlock the potential value in food waste streams. It is a chemically leavened, hard-cookie snack product resembling the shape of a miniature slice of toast. The main ingredient of the cookie is a custom upcycled flour blend, this blend consists of 36.4% brewers spent grain flour (14.8% Kernza® and 21.6% barley) and 63.6% surplus toasted bread scrap flour. The concept of ReToast underlines two major values, that is, sustainability and health as the product contains 30% upcycled ingredients such as spent whole grains that have been found to increase fiber and protein content in baked goods.
