摘  要:
为研究3种天然抗氧化剂(TBHQ、油溶性茶多酚和迷迭香)对云南核桃油稳定性的影响,通过在核桃油样品中添加不同浓度的抗氧化剂,以过氧化值(POV)和酸值(AV)作为油脂稳定性的评价指标,分别测定诱导时间并考察抗氧化效果。结果表明:在云南核桃油中添加单一抗氧化剂时,其抗氧化性能排序为0.02%TBHQ>0.08%茶多酚>0.06%迷迭香;在云南核桃油中添加复合抗氧化剂时,以0.02%TBHQ+0.08%茶多酚+0.06%迷迭香,抗氧化效果显著。

摘  要:
To study the effect of 3 natural antioxidants(TBHQ,oil-soluble tea polyphenols and rosemary)on the stability of Yunnan walnut oil,the induction time and antioxidant effect of these antioxidants were measured through selecting peroxide value(POV) and acid value(AV) as oil stability evaluation index after adding antioxidants with different concentrations.The results showed that the antioxidant performance was 0.02%TBHQ>0.08% tea polyphenol>0.06% rosemary when adding a single antioxidant in walnut oil.The antioxidant performance was 0.02%TBHQ+0.08% tea polyphenol +0.06% rosemary when adding compound antioxidant,and the effect was significant.
