Abstract

Guava is rapidly perish with higher weight loss, fungal decay which limits its marketability. So, this experiment was carried out to study the efficacy of post harvest coating henna leaves extract at (2% and 4%) and sodium alginate at (2% and 4%) on the quality attributes during cold storage and shelf life of "Maamoura" guava fruit. The fruits were stored at 7±1˚C and 90±5% R.H. for 21 days followed by shelf life period at room temperature under conditions (25±2˚C and 65±5% R.H. Fruit quality was evaluated at harvest, during cold storage and evaluate number of days that fruits suitable for market at shelf life. Results showed that, all of post harvest treatments of 4% alginate or 4% henna leaves extract had positively affected postharvest quality properties including decreased weight loss, decay percentage, keeping visual appearance, fruit firmness, total soluble solids, titratable acidity, vitamin C and total soluble sugars during cold storage compared to the control (untreated fruits), the coverage treatments also increased the number of days for the fruits to be marketable. The study suggests that coating treatments can be used for keeping quality for longer time in markets of guava fruits.
