摘要：The present study was carried out on dried chamomile powder to compare yield of extraction , physico - chemical characteristics and sensorial properties of extract s obtained fro m samples irradiated by gamma ray (GR) and electron beam (EB) at 10 kGy and 20 kGy. The results of the present stud y showed that radiation treatment with 10 kGy and 20 kGy of GR and EB did not affect significantly the yield of extra ction . Also , t he viscosity increased in the extract of samples treated with 20 kGy of GR and EB. However, both irradiation doses (10 kGy and 20 kG y) of GR and EB significantly increased the pH value, Mg concen tratio n and L* value of color (l ightness), and decrease the b* value of color (yellowness), but sensory qualities of all extract of the chamomile extract s samples were not significantly different depending o n irradiation types and doses.
