摘要
采用水蒸气蒸馏法提取香茅精油,然后将精油加入花生油中,在65℃的条件下进行加速储藏试验,探究其对花生油储藏氧化稳定性的影响。结果表明:添加香茅精油0.08%(以花生油质量计)的花生油样品在储藏30 d后,其酸价、过氧化值、茴香胺值、硫代巴比妥酸值、共轭二烯值和共轭三烯值相较于对照组分别降低了0.50 mg KOH/g、78.4 mmol O_(2)/kg、12.2、0.91 mg/kg、11.06和9.78,表明香茅精油在花生油储藏过程中有良好的抗氧化作用。可为香茅精油作为天然抗氧化剂的开发提供理论参考。
Citronella essential oil(CEO)was extracted by steam distillation,and then the essential oil was added into peanut oil.The accelerated storage test was carried out at 65℃ to explore the effect of CEO on the oxidation stability of peanut oil.The results showed that compared with the control group,the acid value,peroxide value,anisidine value,thiobarbituric acid value,conjugated diene value and conjugated triene value of peanut oil samples supplemented with 0.08% citronella essential oil(based on the mass of peanut oil)decreased by 0.50 mg K0H/g,78.4 mmol O_(2)/kg,12.2,0.91 mg/kg,11.06 and 9.78,respectively,after 30 d of storage,indicating that the essential oil of citronella had good antioxidant activity during storage of peanut oil.It provided theoretical reference for the development of citronella essential oil as natural antioxidant.
