This innovative process not only caters to chefs and cooking enthusiasts but also contributes to waste reduction. ReSpices efficiently converts food waste, including leftover vegetables such as onions and carrots, into freeze-drying powder, ideal for enhancing the richness of dishes like curry. The reactor utilises the ultra-low temperature resulting from the reaction between ethyl alcohol and dry ice, eliminating the need for an ultra-cold storage freezer. This design ensures a streamlined conversion process with minimal power consumption.
