Abstract


Olive fruits (Olea europea. var. Surrany) treated with 0, 1, 2 and 3 kGy of gamma irradiation were debittered in distilled water for 8 days and stored in brine for 12 months at room temperature. Total dissolved and inorganic dissolved solids, Na, K, Ca, electric conductivity (EC) and pH values were evaluated in washing wastewater (daily), and in brine (after 6 and 12 months). The results showed that gamma irradiation increased the total and inorganic dissolved solids, Na and K in washing wastewater, and in brine throughout debittering and storage periods. Also, gamma irradiation had an effect on EC and pH values of washing wastewater and brine.
