Characterization of glucose-crosslinked gelatin films reinforced with chitin nanowhiskers for active packaging development

[EN] To find renewable and sustainable alternatives to reduce the severe environmental impact of single-use synthetic plastic packaging, glucose-crosslinked gelatin films containing different amounts of chitin nanowhiskers (CNWs) were prepared. CNWs were first prepared by acid hydrolysis of chitin f...
