| Abstract: |
| With low temperature hydraulic pressed Juglans sigillate oil as test object, the oxidative stability of Juglans sigillate oil and the effects of antioxidants on it were studied by Rancimat892 oil oxidation stability tester. The results showed that the shelf life of Juglans sigillate oil without antioxidant was 69 d at 20?℃. When adding the same amount of single antioxidant to Juglans sigillate oil, TBHQ had the best antioxidant effect, followed by PG, BHT, tea polyphenols and vitamine E. When added compound antioxidants to Juglans sigillate oil, the Juglans sigillate oil added with 100 mg/kg TBHQ and 100 mg/kg PG had the longest oxidation induction time, followed by 100 mg/kg TBHQ and 200 mg/kg tea polyphenols, 100 mg/kg PG and 200 mg/kg tea polyphenols, 100 mg/kg TBHQ and 100 mg/kg BHT, and 100 mg/kg BHT and 200 mg/kg tea polyphenols. |
