Finishing Processes for Zein Biodegradable Films
… and coating processes of zein-oleic acid films provided films with range of tensile properties, gas barrier properties, and thermal properties. The range could make zein-based films potentially useful in packaging applications for fresh produce of different respiration rates.

Processing and Characterization of Extruded Zein-Based Biodegradable Films
The objectives of this study were to prepare biodegradable zein films by extrusion processing and to evaluate relevant physical properties of resulting films with respect to their potential as packaging materials. The manufacture of protein-based packaging films by extrusion has remained a …

Extraction and characterization of collagen from bovine hides for preparation of biodegradable films
… Secondly, to prepare and characterize biopolymer films from the extracted collagen. Methods of acid-solubilisation (AS), acid-enzyme solubilisation (AES1) and a modified method of acid-enzyme solubilisation (AES2) were applied to extract collagen from bovine hide off-cuttings of bull, calf, cow, …

Development of biodegradable microfluidic networks for tissue engineering
Biodegradable tissue engineering scaffolds currently suffer from poorly controlled geometries, lack of reproducibility, and severe mass transport limitations. Microfabrication is an ideal tool for attacking problems in tissue engineering due to its control of diverse size scales, from microns to …

Generation of sustainable active food packaging materials from agricultural wastes
… alternative food packaging materials that are biodegradable and/or environmentally friendly. Aim: This project investigated the utility of cassava waste (cassava peel) in producing sustainable active food packing materials using various plasticisers as well as the effects of supplementation of …

Characterization of zein extracted from beer solids, a coproduct of dry-grind ethanol
… for flavor encapsulation, in moisture barrier films, as chewing gum base. Most recently, it has been explored in biomedical applications as tissue scaffolding, to enhance cell spreading and viability. Coproducts of corn-to-ethanol processing remain potential sources of zein. Distillers’ wet …

Promoting pulp and paper mill material circularity: functionalised organic-inorganic cellulosic mulch films
… fossil-fuel-based synthetic mulch films have been used to mitigate soil water loss, as a matrix for the slow-release of fertiliser, and for UV-vis light blocking to retain water, limit nutrient loss and prevent weed growth, respectively. However, microplastics remaining from poorly …
