Researcher Itsaso Leceta’s team of scientists at the UPV/EHU-University of the Basque Country published a paper entitled “Quality Attributes of MAP Packaged Ready-to-Eat Baby Carrots Following the Application of Chitosan-based Coatings,” which deems chitosan, made from crustacean shells, a potential petroleum food packaging substitute.

Made from the shells of prawns and king prawns, chitosan packaging achieves the same preservation goals as petroleum-based packaging, and is far more environmentally friendly, according to the paper,.

Last year, this unique material was explored by a European Union project called n-CHITOPACK and a 2011 Journal of Food Science study referenced chitosan-based edible coatings. As research in this realm continues, it becomes more likely that chitosan-based packaging will appear on the market in the near future.
