Studies on the storage of Egyptian Siwi date variety were con-ducted in order to lower the changes in chemical and sensory character-istics and to prevent the insect infestation. The following treatments were used to reach this target: preservation of dates by packing in sealed plastic containers, using polyethylene-polyamide bags for packing dates under vacuum and treating the dates by sulfur dioxide in the store. previous treatments were stored in tightly closed store for eleven months. The results revealed that treating Siwi dates of Kharja and Dakhla Oasis by sulfur dioxide led to the best color (10.36 and 11.82 ICUMSA respectively for the date extract) and total color density were very low for the same treatment (0.324 and 0.367 OD respectively). The unac-ceptable color appeared in the dates packed in plastic containers. No in-sect infestation was found in any treatments.
