Abstract
The effects of gamma irradiation and ozone treatment on the microbiolo gical and physicochemical qualities of aloe powders were compared. Gam ma irradiation at 10 kGy could reduce total aerobic bacteria, moulds a nd coliforms below detection levels, but ozone treatment up to 18 ppm for 8 h was not sufficient to achieve the same effect. The fatty acid and amino acid compositions, minerals, TBA value, barbaloin and pigmen ts were not significantly changed by gamma irradiation, whereas ozone treatment caused significant changes in fatty acid composition, lipid oxidation and the destruction of barbaloin and natural pigments.
