Biodegradable films from DDGS

Abstract

One or more embodiments of the invention are directed toward biodegradable films from distiller's dried grains with solubles (DDGS), especially sorghum DDGS, and methods of making the same. The films, which are suitable for use as packaging films, can be produced by directly conditioning the DDGS via a milling process, such as wet milling (e.g., colloid mill and ball milling) in water or a sodium hydroxide solution. The milled slurry is co-dissolved with plasticizers and stabilizers (preferably all less than 1% by weight) in a mixture of water and an organic solvent. The mixture is then used for film processing via pour-casting. The biodegradable films have significant antioxidant and antimicrobial activities related to their phenolic content.
