| 采用Schaal烘箱法，以过氧化值和α-亚麻酸含量为指标，比较了3种脂溶性酚类及人工合成抗氧化剂对紫苏籽油的抗氧化效果。结果表明，当抗氧化剂添加量为100 mg/kg时，基于过氧化值的抗氧化效果为香芹酚＞百里香酚、丁香酚＞BHT、BHA。低添加量抗氧化剂(1~100 mg/kg)紫苏籽油中α-亚麻酸含量均高于不添加抗氧化剂的处理组。香芹酚的最适添加量为5 mg/kg，α-亚麻酸含量为6.399 mg/g，与4?℃保存的紫苏籽油含量相近；BHT的最适添加量为50 mg/kg，α-亚麻酸含量为6.987 mg/g，高于4?℃保存的紫苏籽油；分别添加100 mg/kg的香芹酚与100 mg/kg 的BHT的紫苏籽油中α-亚麻酸含量相近，说明二者抗氧化能力相当。研究结果证实了香芹酚、百里香酚、丁香酚对紫苏籽油具有较好的抗氧化作用，为安全高效的天然酚类抗氧化剂的筛选及其在油脂食品中的应用提供理论参考。 |
| 英文摘要: |
| The antioxidation effects of three liposoluble phenols and synthetic antioxidants on perilla seed oil were researched by Schaal oven-storage test with peroxide value (POV) and α-linolenic acid content as indexes. The results showed that the antioxidant effects of carvacrol was the strongest, followed by thymol and eugenol， BHT and BHA based on POV when the dosage of antioxidants were 100 mg/kg， and α-linolenic acid contents of all groups with low dosage of antioxidants (1-100 mg/kg) were higher than those without antioxidant. The optimal dosages of carvacrol and BHT were 5 mg/kg and 50 mg/kg with α-linolenic acid contents of 6.399 mg/g and 6.987 mg/g， respectively. The α-linolenic acid content in carvacrol adding group was similar to the content in the group conserved at 4?℃ while the BHT adding group was higher. When 100 mg/kg of antioxidants was added，the α-linolenic acid content of carvacrol adding group was close to that of BHT adding group， which indicated comparable antioxidant effect of the two antioxidants. The study confirmed that the antioxidation effects of carvacrol， thymol and eugenol on perilla seed oil were good，which provided a theoretical reference on screening of safe and efficient natural phenolic antioxidants and the relevant application in fatty foods. |
