Aerobic biodegradation
60% disintegration rate (CO2 produced) in ~10 days; three-stage TGAs: first degradation ~61–63°C [68], second degradation ~257°C, and maximum disintegration ~280–290°C
Degradation time 6-12 days exhibited changes in tonality and breakdowns materials. Three-stage TGAs: first degradation ~100–150°C [68], second degradation ~180–60°C, and maximum disintegration ~250-350°C
Zein-chitosan-poly(vinyl alcohol)—PEF treated (between 60–70 kJ/kg and 600–620 kJ/kg)
In vitro degradation (enzymatic susceptibility)
Amine content: ~0.02 mM Scrine Eq in 30 min; amino acids increase between 60 and 260 min (0.02-0.04 mM Scrine Eq). Higher energy yielded higher amino acids
