Changes in TVC in salmon slices treated with gamma radiation and cinnamon oil during storage. BF, salmon slices at the beginning without inoculating S. putrefaciens; AF, salmon slices at the beginning after inoculating S. putrefaciens; 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 with 2 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).

Effect on hepatic ROS production. ESR signal intensity of CMH-detectable ROS in liver of rats fed diets with either soybean oil or salmon oil with various vitamin E concentrations. (A) Bars represent total ROS using the spinprobe molecule CMH and are means ± SD from 8 animals per group; ^a,b values with different superscript letters differ significantly (P < 0.05). (B) Representative ESR spectra of samples are shown for 1 animal per group (A, diet with soybean oil and 25 vitamin E/kg; B, diet with soybean oil and 250 vitamin E/kg; C, diet with soybean oil and 2500 vitamin E/kg; D, diet with salmon oil and 25 vitamin E/kg, E, diet with salmon oil and 250 mg vitamin E/kg; F, diet with salmon oil and 2500 mg/kg vitamin E)

Changes in pH values in salmon slices treated with gamma radiation and cinnamon oil during storage. 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 with 2 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–b) are significantly different within the different treatments on the same storage days (p < .05).

Changes in total volatile bases nitrogen (TVB‐N) in salmon slices treated with gamma radiation and cinnamon oil during storage. 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 with 2 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).
