Abstract

In this study, the effects of γ-radiation on physicochemical properties of Iranian Saffron (Crocus sativus L. ) such as crocin (Saffron color factor), kaempferol (polyphenol Bioactive Compounds) and safranal (the main component of volatile aromatic Saffron), color paramerters a*, b*, L* and Δ Eh indices and the Microbial Load were investigated. The Saffron samples were irradiated at dosages of 0, 1, 2, 3, 4, 5 and 6 kGy by a Gammacell 220. Then, the efficient compounds were extracted and the composition and Microbial Load of Saffron extracts were determined before and after the γ-irradiation. The results showed that in addition to decreasing the microbial content of Saffron, among the 21 bioactivie compounds separated by HPLC, crocin, kaempferol and safranal content in three regions of this study were affected by the Gamma Irradiation. Pre-treatment of Saffron with 4 and 6 kGy radiation also results in a significant (p<0. 01) increase, without changes in color and bioactivie compounds. These data may suggest that irradiation of Saffron without unfavorable changes on the effective componeents results in a significant decrease in the microbial content of this product.
