BACKGROUND

In the present study, tara seed oil was obtained by supercritical fluid extraction and used to investigate the antioxidant strength of carnosic acid (CA) compared with conventional synthetic antioxidants.

METHODS

The antioxidants were added to the tara seed oil at 0.2 mg of antioxidant per gram of oil. The samples were then submitted to at 60 °C 15 days for an accelerated oxidation process, with samples taken regularly for analysis. After oxidation, the samples were analyzed to determine the peroxide value, thiobarbituric acid reactive substances, conjugated diene content, and free fatty acid content. CA was investigated at three purity levels (CA20, CA60, CA99), and compared with three synthetic antioxidants (butylatedhydroxyanisole, butylatedhydroxytoluene, and tert-butylhydroquinone).

RESULTS

The oxidation indicators showed that CA was a strong antioxidant compared to the synthetic antioxidants. The antioxidant activities decreased in the order: tert-butylhydroquinone > CA99 > CA60 > CA20 > butylatedhydroxyanisole > butylatedhydroxytoluene. These results show that CA could be used to replace synthetic antioxidants in oil products, and should be safer for human consumption and the environment.

背景

在本研究中，通过超临界流体萃取获得塔拉籽油，并用于研究与传统合成抗氧化剂相比，鼠尾草酸（CA）的抗氧化强度。

方法

将抗氧化剂以每克油0.2毫克抗氧化剂的量添加到塔拉籽油中。然后将样品在60℃下放置15天进行加速氧化过程，定期取样进行分析。氧化后，对样品进行分析以确定过氧化值、硫代巴比妥酸反应性物质、共轭二烯含量和游离脂肪酸含量。研究了三种纯度水平的CA（CA20、CA60、CA99），并与三种合成抗氧化剂（丁基羟基茴香醚、丁基羟基甲苯和叔丁基对苯二酚）进行比较。
