Study of the Influence of Preparation Conditions of γ-PGA Ester as a Food Packaging Material on the Biodegradation Performance

As people enhance consciousness on food safety and environmental protection, the research of food packaging materials has been widely noted. Non-degradable disposable food packaging plastics as the most common food packaging materials have some disadvantage such as harmful substances migration, air pollution and waste of land resources. gamma-PGA ester is a new kind of food packaging materials which attracted the attention of the researchers due to its non-toxic and biodegradable. This study analyzed the influence of preparation conditions of gamma-PGA ester as a food packaging material on the biodegradation performance through the orthogonal experiment methods which provide references for the related researchers.
