摘  要:
比较天然迷迭香、茶多酚与复配BHA和BHT对油脂氧化稳定性的影响,通过Rancimat法快速测定了添加不同配比的迷迭香、茶多酚及复配BHA和BHT的棕榈油样品的诱导时间,结果表明:在棕榈油中抗氧化稳定效果分别为迷迭香150 mg/kg>茶多酚2 000mg/kg>迷迭香100 mg/kg>BHT 60 mg/kg+BHA 60 mg/kg>迷迭香50 mg/kg>迷迭香30 mg/kg>茶多酚500 mg/kg。迷迭香50 mg/kg的抗氧化性能与复配BHT和BHA效果相近,具备较好的应用前景。

摘  要:
This paper studied on the effect of anti-oxidation of rosemary,tea polyphenols and composite stabilizer of BHA&BHT on oxidative stability of palm oil by the method of Rancimat.The induction time of samples which have different ratios anti-oxidation of rosemary,tea polyphenols and composite stabilizer of BHA&BHT was determined,the results showed that the anti-oxidation of antioxidants in palm oil was rosemary150 mg/kg>tea polyphenols2 000 mg/kg>rosemary 100 mg/kg>BHT 60 mg/kg+BHA 60 mg/kg>rosemary 50 mg/kg>rosemary 30 mg/kg>tea polyphenols500 mg/kg.Rosemary 50 mg/kg had better selectivity in the comparison,it has great prospect of application.
