EDTA System for Reducing Browning in Mycohide Materials

A system and methods for reducing browning in fungal materials and objects therefrom, and in particular to a method for reducing browning in processed fungal materials. Provided are particular methods for reducing browning in fungal materials via application of a chelating agents, heat, a combination of chelating agents and heat, and various other processes described herein. Reduction of browning is applied to mycelium sheets in various wet processing stages including fermentation, plasticization, and in temperature treated samples. Reduced browning allows for control of the appearance of fungal biopolymers while also impacting mechanical properties such as tensile strength, tear strength, and abrasion resistance.
