CK, untreated salmon slices group; G, salmon slices group treated with 2 kGy gamma radiation; C, salmon slices group treated with 1% (v/v) cinnamon oil; G + C, salmon slices group treated with2 kGy gamma radiation and 1% (v/v) cinnamon oil. Values were expressed as mean ± SD (n = 3). Bars with the different letter (A–C) are significantly different within the same treatment on different storage days (p < .05); Bars with different letters (A–D) are significantly different within the different treatments on the same storage days (p < .05)
