Fast determination of Sudan I by HPLC/APCI-MS in hot chilli, spices, and oven-baked foods.
The Commission Decision of EC dated 20 June 2003, on emergency measures concerning hot chilli and hot chilli products coming into any EC member state, required that the consignments of such products should be accompanied by an analytical report showing that they are free of artificial dye Sudan I. The opportunity to set a confirmatory method is evident, and the paper proposes a HPLC/APCI-MS met...
متن کاملDetermination of Phylloquinone and Menaquinones in Foods by Hplc
High-performance liquid chromatographic (HPLC) methods for determining vitamin K contents in oils and margarines, vegetables, fruits and berries, cereals and animal products were developed. These methods were applied to analysing phylloquinone and menaquinone in a total of 87 food items. In addition, the 2 ́,3 ́-dihydrovitamin K1 contents of a few margarines and hydrogenated oils were determined,...
متن کاملDetermination of bisphenol A in canned fatty foods by coacervative microextraction, liquid chromatography and fluorimetry.
Decanoic acid reverse micelle-based coacervates were used to provide simple, rapid and almost solventless extraction of bisphenol A (BPA) from canned fatty foods. The procedure involved the extraction of 200-400 mg of homogenised food sample with an aqueous solution containing 20% THF and 200 mg of decanoic acid, conditions under which the coacervate (around 550 microl) formed in situ and insta...
متن کاملExtraction and Determination of Cyproheptadine in Human Urine by DLLME-HPLC Method
Novel dispersive liquid-liquid microextraction (DLLME), coupled with high performance liquid chromatography with photodiode array detection (HPLC-DAD) has been applied for the extraction and determination of cyproheptadine (CPH), an antihistamine, in human urine samples. In this method, 0.6 mL of acetonitrile (disperser solvent) containing 30 µL of carbon tetrachloride (extraction solvent) was ...
