Method & Evidence

AimTo demonstrate the industrial-scale feasibility of producing transparent, flexible bioplastic films from soy waste byproducts for use in packaging.
MethodIndustrial-scale proof of concept and material characterization.
ProcedureAmyloid fibrils were self-assembled from soy whey and okara (tofu manufacturing byproducts). These fibrils were combined with methylcellulose and glycerol to create bioplastic films. A 500 L batch of soy whey was processed to produce approximately 1 km (27 kg) of film. This film was then industrially processed into transparent windows for paper-based packaging. Mechanical properties and water interactions were tested and compared to commercial plastic films.
Sample500 L of soy whey processed
