It is worth
noting that these characteristics are maintained even following storage of the films at 4 ◦C or −20 ◦C,
suggesting that our bioplastics can be tailored to protect food at low temperature. Moreover, gastric
and duodenal digestion studies conducted under the same conditions found in the human digestion
system have demonstrated that transglutaminase-containing films are regularly digested encouraging
an application of the proposed materials as food coatings.
