Whey, a major by-product from dairy processing, is considered a promising source for biodegradable film and coating materials to replace plastics in food packaging. However, low strength and poor water barrier properties of whey protein-based films are major challenges that limit their industrial use. This project will use lignin, a natural plant polymer, to improve whey-protein film. The research team will also define how the film can be used in large-scale processing facilities. Grace Lewis is collaborating on this project and equipment from UW–River Falls and UW–Madison will be use to measure characteristics of the films.
