中文摘要 | 本研究利用固相萃取前處理及梯度移動相之高效液相層析方法,配合可見光檢測器,同時檢測食用油脂中四種蘇丹色素(Sudan I~IV)。檢體經過固相萃取匣(alumina材質)淨化,再經RP18層析管柱(4.6 × 150 mm)與乙腈及0.1%甲酸混合溶液之梯度移動相分離,於波長500 nm偵測。添加0.1~5.0 ppm蘇丹一號、蘇丹二號、蘇丹三號及0.13~6.5 ppm蘇丹四號之4種蘇丹色素回收率分別為,蘇丹一號74.17~98.33%、蘇丹二號91.28~106.73%、蘇丹三號87.01~91.35%及蘇丹四號83.01~102.58%。食用油脂之4種蘇丹色素最低檢出限量均為0.05 ppm。本計畫共檢測包括辣椒油、沙拉醬及食用油脂等60件檢體,均未檢出4種蘇丹色素。 |
英文摘要 | A HPLC method was developed for the simultaneous determination of four kinds of sudan dyes (I, II, III and IV) in edible oils. Samples were first applied into an alumina SPE cartridge and eluted with 75% ethyl acetate in methanol. HPLC was performed as follows: a RP-18 column eluted with 0.1% formic acid/acetonitrile mixture as mobile phase in gradient at a flow rate of 1 mL/min. Sudan I, II, III, and IV in edible oils were identified and quantified with absorbance at 500 nm. None of these sudan dyes were detected in 60 edible oil samples. |
