Bacterial cellulose for food packaging

A method of producing a biodegradable film, the method comprising:

• culturing a symbiotic colony of bacteria and yeast (SCOBY) in a cultivation medium under culture conditions suitable for synthesis of a bacterial cellulose matrix entrapping protein, wherein the cultivation medium comprises a sugar, a tea, and a protein mixture including the protein;
• harvesting the bacterial cellulose matrix;
• coating the bacterial cellulose matrix with a coating solution under conditions suitable for forming coated bacterial cellulose, wherein the coating solution comprises an ionic polysaccharide and a polyether;
• and
• contacting the coated bacterial cellulose with a crosslinking solution under conditions suitable for crosslinking the coated bacterial cellulose, wherein the crosslinking solution comprises a metal salt, thereby forming the biodegradable film.
