Postharvest life of strawberry fruit is very short due to humidity and high metabolic activity. In order to extend the shelf life and quality of strawberry (cv. parous), effects of pectin coating enriched with different concentrations of lemon and orange peel essential oil were assessed at 20˚C for 6 days or 5˚C to 12 days. The experiment conducted based on a complete randomized design (CDR) in...
