Abstract

The aim of this research was to study the effect of edible coating with alginate and calcium chloride on postharvest quality of strawberry fruits during low temperature storage. Strawberry fruits cv. Paratchatan 80 were harvested at 70-80 percent color break.  Strawberry fruits were cleaned by soaking in 100 ppm of ozonated water for 30 second and coated with single solution of alginate (0.25,0.5,1.0%), calcium chloride (2%CaCl2) or the combination coated with 2%CaCl2 solution and alginate solution (0.25,0.5, 1.0%). All fruits were air dried and packed in clamshell tray and stored at low temperature (5±2ºC,80%RH) for 15 days and then transferred to ambient temperature (25±2ºC,65%RH) for 2 days. Results showed that all coated treatments with alginate in single solution treated or combination treated had effectively delayed weight loss, mold development, maintained postharvest quality and extended shelf life of strawberry fruits during low temperature storage. Fruits coated with 0.5% alginate combination 2%CaCl2 showed the best quality and extended shelf life for 17 days while the control had 10 days shelf life.
