Abstract

Abstract This study aimed to examine the physicochemical changes in calliandra honey ( Calliandra callothyrsus ) induced by gamma irradiation treatment. Calliandra honey, produced by Apis mellifera bees, was subjected to gamma irradiation at doses of 0 kGy (non-irradiated) and 10 kGy. The study focused on evaluating parameters such as color characteristics, pH, water activity (AW), and moisture content. Additionally, functional groups were analyzed using Fourier transform infrared (FTIR) spectroscopy. The gamma irradiation process has no significant effect on the lightness (L*), pH, water activity (AW), or moisture content of calliandra honey. However, it notably decreases the redness parameter (a*) from -0.77 to -1.93 (p
