In military terminology, a “ration” refers to the daily food allotment for one service member. An “operational ration” is a broad category covering rations designed for use in combat zones and during field operations. Key considerations in developing such rations include healthfulness, nutritional value, and oxidative stability to ensure a long shelf life under adverse conditions. In the Iranian armed forces, dates are a common component of the operational ration. A primary concern with any food ration is extending its preservation period. Various techniques exist to enhance the shelf life of dates, including irradiation and modified packaging. This study examines the combined effect of packaging methods and gamma irradiation on the sensory properties of Shahani dates. The experiment followed a completely randomized design with three treatments and three replications: Treatment 1: Control (vacuum packaging only), Treatment 2: Vacuum packaging combined with gamma irradiation at a dose of 4 kGy and Treatment 3: Vacuum packaging combined with gamma irradiation at a dose of 6 kGy. Sensory evaluations were conducted on samples stored at room temperature at 6, 12, 18, and 24-month intervals. The results indicated that after 24 months, Treatment 2 (vacuum packaging with 4 kGy irradiation) received the highest sensory scores and demonstrated the greatest shelf life.
