Conclusion
Pineapple shell extract (PSE) showed ability to reduce browning value in banana more
effectively than that of citric acid solution and distilled water. The increase of browning in banana
treated with PSE seemed to be less than that of potato, mushroom and apple during storage. It
suggested that the pineapple shell extracts have a potential to be used as a natural antibrowning
agent for banana.
