| Abstract | ||
| The aim of this study was to evaluate the effect of chitosan and thymol postharvest dipping on maintaining fruit quality attributes of Sultani figs. Ripe fig fruits gently picked manually and treated with 0.3 or 0.6 mM thymol and 2.5 or 5 g/L chitosan in addition to water treatment then stored at 0°C and 85-90 % RH. A Samples of stored fruits were taken every week to estimate determine fruit quality and storability. The results of the study showed that chitosan treatments significantly reduced fruit weight loss and shriveling percent up to three weeks as compared with the untreated fruit. Thymol and chitosan treatments decreases the percentage of decay incidence and quantitative losses after one, two or three weeks of cold storage plus two days at room temperature especially at the high concentration. All treatments caused a decrease in the percentage of quantitative losses after two or three weeks of storage as compared to control and 0.3 mM thymol. Chitosan significantly maintained fruit firmness, SSC, total and non-reducing sugars up to 3 weeks. In addition, thymol and chitosan treatments had higher phenolic content than control after 1 or two weeks. | ||
