Composition of Genuine Cocoa Butter and Cocoa Butter Equivalents
Abstract The compositional variation of the fatty acid, triacylglycerol, tocopherol, tocotrienol and sterene composition of genuine cocoa butter (CB) due to different geographical growing regions and… Expand
Photochemistry of dibenzoyl methane UVA filters Part 1
Two dibenzoyl methane derivatives, 4-isopropyldibenzoyl methane (I-DBM) and 4-t-butyl-3′-methoxydibenzoyl methand (BM-DBM), have been found to be photolabile towards UVA light in non-polar solvents,… Expand
Degree of hydrolysis of some vegetable proteins used as fining agents and its influence on polyphenol removal from red wine
The increasing demand for economic and efficient wine fining leads to the search for alternatives to traditionally used proteins, preferably new products with the side effect of non-allergenicity. A… Expand
Determination of isopropylthioxanthone (ITX) in milk, yoghurt and fat by HPTLC-FLD, HPTLC-ESI/MS and HPTLC-DART/MS
AbstractTwo new HPTLC methods for quantification of isopropyl-9H-thioxanthen-9-one (ITX) in milk, yoghurt and fat samples have been developed. Extraction of ITX from milk and yoghurt was performed… Expand
Determination of free and bound carotenoids in paprika (Capsicum annuum L.) by LC/MS
Analysis of carbendazim, benomyl, thiophanate methyl and 2,4-dichlorophenoxyacetic acid in fruits and vegetables after supercritical fluid extraction.
Simple methods for the analysis of carbendazim, benomyl and thiophanate methyl in fruits and vegetables and of 2,4-D in citrus fruits are presented. Sample preparation involves supercritical fluid… Expand
Planar solid phase extraction--a new clean-up concept in multi-residue analysis of pesticides by liquid chromatography-mass spectrometry.
Efficient clean-up is indispensable for preventing matrix effects in multi-residue analysis of pesticides in food by liquid and gas chromatography coupled to mass spectrometry. As a completely new… Expand

The simultaneous determination of dithiocarbamate (DTC) fungicide residues on fruits and vegetables was performed by liquid chromatography (LC) on a ZIC-pHILIC column coupled to tandem mass… Expand
Coupling of planar chromatography to mass spectrometry
Coupling of planar chromatography to mass spectrometry (MS) and especially ambient MS is a relatively new field of great interest. The direct sample access at ambient conditions and the feasibility… Expand
Hyphenations in planar chromatography.
This review is focused on planar chromatography and especially on its most important subcategory high-performance thin-layer chromatography (HPTLC). The image-giving format of the open, planar… Expand
