Abstract

Food-borne microbes from sweet orange, okra and pepper were homogenized and combined based on fruit type. The homogenized mixtures of the isolates were subjected to Ultraviolet radiation using a fabricated irradiation system to determine the total viable colony count post-irradiation. This was used in calculating the decimal reduction doses for the crops, which were found to be 2.589 Jm-2, 2.556 Jm-2 and 4.133 Jm-2, for Sweet Orange, Okra, and Pepper, respectively. These doses will be helpful in the sterilization and shelf-life extension of the selected fruits and vegetables.
