中文摘要 | 本研究建立了市售魚油膠囊中TBHQ(第三丁基氫醌,tertiary-buthyl hydroquinone)之快速氣相層析定量法。1-2滴(30-60 mg)之油脂樣品以1 mL乙酸乙酯溶解後,加入100 µL 0.01% (w/v)之8-quinolinol (8Q)內標準溶液,即可直接注入氣相層析儀之分析之。添加回收實驗中,TBHQ之回收率為95-108%,變異係數均小於7.5%。以本方法測定10件市售魚油膠囊之TBHQ含量為:0-259 µg/g。10件樣品中檢出含TBHQ者達7件,其中3件魚油膠囊之抗氧化劑含量達215-259 µg/g,超過CNS之標準添加量200 µg/g之規定。 |
英文摘要 | In this study, a rapid and simple method without a derivatization process for determination of the synthetic antioxidants, TBHQ (tertiary-butyl hydroquinone) in commercial fish oil capsules was developed. In 1-2 drops (about 30-60 mg) of the sample, 1 mL etheyl acetate and 100μL 0.01% 8-quinolinol was added and thouroughly mixed, and 0.1μL of the etheyl acetate solution was then direct injected to GC for TBHQ analysis. The recoveries of TBHQ from commercial fish oil capsule was at the range of 95-108%, with a coefficient of variation less than 7.5%. 10 samples of fish oil capsules were analyzed using the developed method. The contents of TBHQ were found to be 0-259 μg/g in ten capsule samples tested. These were severn capsules containing TBHQ. The TBHQ contents of three fish oil capsules were in the range of 215-259μg/g, which exceeded the Taiwan National Standard (CNS) regulation levels of 200μg/g in edible oil. |
