Summary
Tomato (Lycopersicon esculentum L) is one of the most widely consumed fresh vegetable. However, its highly perishable nature limits its postharvest life. Temperature and relative humidity management to extend shelf life and maintain postharvest quality of perishables is the main problem in tropical countries like Ethiopia. Though mechanical refrigerators are the best option to do, it is unaffordable for farmers and small retailers in developing countries to buy and run. So development of cheap storage is important task to overcome the problem. The current study conducted to determining the effect of different storage methods and ripening stages on shelf life and postharvest quality of tomato. A factorial CRD design was laid with two factors being storage methods (ZECC, pot in pot storage, desert cooler and the control), and two ripening stages (breaker and light red stage) with three replications. Average daily temperature, relative humidity, shelf life, deterioration and weight loss percentage, titratable acidity, total soluble solid, fruit firmness, Lycopene, beta -carotene, Chlorophyll A and B were evaluated as response variables. Result of the study showed that retaining of tomato postharvest quality and shelf life were much better inside evaporative coolers as compared to control. Weight loss and deterioration percentage, Total Soluble Solid, Lycopene and beta -carotene content increased with the storage period, but were faster on tomatoes stored at room temperature. Titratable acidity, fruit firmness, Chlorophyll A and B contents were decreased with the storage periods compared with control. In this study concluded that evaporative coolers gives an alternative approach on temperature and relative humidity management to mechanical refrigerator.
