Berries were stored at 22˚C and 38% RH as received (no coating) and after coating with silk fibroin suspension (Dx-xx%). Dx stands for ‘x’ dip coating steps. xx% stands for relative content of beta-sheets structures in the silk coating. The
amount of beta-sheets was modulated by varying the exposure time to water annealing process. Thus, D1-58% refers to strawberries that were dip coated 1 time in silk fibroin solution and that were exposed to a water annealing process that yielded 58% of beta-sheets in the protein structure
