Description
Plastic wrap harms the earth, so Peng Huang and co-authors built an edible film that can keep plums fresh, in a 2026 study. The film blends three natural gums: pullulan, konjac gum, and a low-acyl form of gellan gum, with glycerol to keep it soft. Films made from one gum tend to be weak or let too much water vapor pass. The team tuned the blend with planned tests and a surface-fit method to find the best mix.
The best film, at set levels of each gum, looked clear and smooth, with a tight, dense core. Scores for strength and vapor block were strong in tests. The film also slowed germs, broke down in soil, and kept plums fresh for longer in storage trials.
