4. Conclusion
This study demonstrated the effectiveness of chitosan coating containing LPOS in postharvest conservation of mangoes.
Chitosan has antimicrobial activity which was been strengthened by the LPOS.
A chitosan concentration at 1% containing LPOS was sufficiently effective against microbial contamination and enabled a delay in fruit ripening without altering quality.
If chitosan coating had an effect on the physico-chemical properties, the presence of the LPOS did not affect those parameters.
Use of chitosan–LPOS could thus be an effective approach in the preservation of tropical fruit, an alternative in limiting synthetic pesticide use.
