Poly(lactide)(PLA) /cinnamaldehyde composite film was prepared to extend the shelf-life of freshcut apples.The changes in firmness,color,polyphenol oxidase(PPO) activity,sensory quality,and microorganism populations were monitored during 16 days storage at 5°C.The respiration rate,browning,the reduction of firmness,PPO activity,and the increase of microorganism were significantly inhibited by PLA-based films containing with cinnamaldehyde.The results showed that PLA /cinnamaldehyde composite film could effectively extend the shelf-life of fresh-cut apples compared to pure PLA film and low density polyethylene(LDPE) film.
