Abstract
The effects of gamma irradiation and ozone treatment on microbiologica l and physicochemical properties of bee pollen were investigated. Gamm a irradiation at 7.5 kGy reduced the total microbial loads below detec tion levels (>10(2) CFU g(-1)), but after ozone treatment of up to 18 ppm for 8 h the total aerobic bacteria were found in concentrations of more than 10(3) CFU g(-1) Physicochemical properties such as amino ac id and fatty acid composition, thiobarbituric acid value, mineral cont ent, and pigment were not significantly changed by gamma irradiation, whereas ozone treatment caused significant changes in fatty acid compo sition, thiobarbituric acid value, and pigment by lipid oxidation and decoloration (P < 0.05).
