Abstract
Khalas and Sukkary dates varieties were treated with two doses of gamma irradiati0'l (0.5 and 1.0 kGy) in addition to control (untreated dates) were stored under relative moisture of (70-80%) and temperature ranged from (20-25 0c) for 36 weeks. They were used In this study to produce and evaluate its dibis (date syrup).
The results revealed that the date, which treated with 1.0 kGy for the two cultivars, produced the best quality of dibis. The highest reduction of moisture content was observed in untreated samples in each cultivar. The treated samples with (1.0 kGy) are succeeded in preserving total sugars of fruits during storage of both Khalas and Sukkary cultivars. The total soluble solids percentage was increased in fruits by prolonging the storage period In all treatments of date cultlvars under study. Also, the high irradiation treatment (1.0 kGy) succeeded to increase viscosity within to limited permission in fruit of all date cultivars under study. It also keeps the best flavor of dates dibis during storage of both Khalas and Sukkary, At last, the irradiation treatments succeeded to keep the best Ravor, texture and color of date dibis during storage of both Khalas and Sukkary.
