Abstract

In this study proteins extracted from prepupae of Hermetia illucens, also known as black soldier fly,are investigated as promising base for a new type of bioplastics for agricultural purposes. Designof experiments techniques are employed to perform a rational study on the effects of differentcombination of glycerol as plasticizer, citric acid as cross-linking agent and distilled water as solventon the capability of proteins to form a free-standing film through casting technique, keeping asfixed the quantity of proteins. Glycerol shows interesting properties as plasticizer contributing tothe formation of homogenous and free-standing film. Moreover, mechanical and thermalcharacterizations are performed to estimate the effect of increasing amounts of proteins on thefinal properties and thickness of the specimens. Proteins derived from H. illucens can be success-fully employed as base for bioplastics to be employed for agricultural purposes.
