Irradiation is an effective alternative to other preservative techniques.This study aimed at assessing the effects of Diagnostic X-rayson some physicochemical properties and the shelf life of four mango Varieties (Broken, Dawshia, Julie, and the Peter variety) grown in Benue State, Nigeria. Mango samples at the green mature stage were subjected to X-rays within the range of 60-100 kVp and stored at room temperatures (27-30 oC). Data regarding Physicochemical properties and shelf-life were collected following laboratory guidelines. Results reveal an increase in density, moisture content, and pH with mango ripening. Ripening and increase in physicochemical properties were faster in controlled samples than in irradiated samples. Mass shrinkage was equally observed to be higher and faster in the controlled samples than in the irradiated samples. This resulted in higher shelf life (11 days) in irradiated samples than in controlled samples (7 days). Diagnostic X-rays can be used in mango preservation.
