Description

In this study, the effects of γ-radiation on microbial load and efficient compounds derived from caraway seeds were investigated. Caraway seeds were irradiated at dosages of 10 and 25 kGy by a Co60 source. Then the efficient compounds were extracted and the composition and microbial load of caraway extracts were evaluated before and after γ-irradiation. The results showed that while decreasing the microbial content of caraway seeds, among the 22 oil fractions separated by GC-MS, only three components were markedly affected by gamma irradiation. Pre-treatment of caraway seeds with 10 and 25 kGy radiation also results in a significant (p<0.05) increase in flavonoids content of hydro alcoholic extract. These data may suggest that irradiation of caraway seeds without unfavorable changes on their effective components results in significant decrease in microbial content of this product.
