Apple Dye

Inten­tion:
The project’s goal is to extract and enzymat­ic­ally oxid­ize poly­phen­ols in a large-scale indus­tri­al pro­cess to receive nat­ur­al dyes for food. The poly­phen­ols would be derived from apple pomace, mean­ing the squeezed resid­ual mater­i­al obtained dur­ing the pro­duc­tion of apple juice.
