MCPD fatty acid esters in vegetable oils: formation, analysis and toxicology
3-monochoropropane-1, 2-diol (3-MCPD) and 2-monochloropropane-1,3-diol (2-MCPD) and glycidol esters (GE) have been known as food contaminants. These compounds are formed during high-temperature process of different food products such as coffee, edible oils, infant formula, potato based products, bakery products, malt, cooked meats, soy sauces and pickles. In vegetable oils, these compounds are ...
متن کاملAnaLYsIs oF Sucrose FattY AcID Esters
Supercritical uid chromatography (SFC) coupled with triple quadrupole mass spectrometry was applied to the pro ling of sucrose fatty acid esters (SEs). e SFC conditions (column and modi er gradient) were optimized for the e ective separation of SEs. In the column test, a silica gel reversed-phase column was selected. en, the method was used for the detailed characterization of commercial SEs an...
متن کاملDirect Determination of MCPD Fatty Acid Esters and Glycidyl Fatty Acid Esters in Vegetable Oils by LC–TOFMS
Analysis of MCPD esters and glycidyl esters in vegetable oils using the indirect method proposed by the DGF gave inconsistent results when salting out conditions were varied. Subsequent investigation showed that the method was destroying and reforming MCPD during the analysis. An LC time of flight MS method was developed for direct analysis of both MCPD esters and glycidyl esters in vegetable o...
متن کاملCrystallization Behavior of Fatty Acid Methyl Esters
Biodiesel from most agricultural feedstocks has flow properties that are prone to startup and operability problems during cold weather. Biodiesel from soybean oil is generally a mixture of long-chain fatty acid alkyl esters composed of 0.15–0.20 mass fraction saturated esters (melting point [MP] 0 C) mixed with unsaturated esters (MP \ 0 C). This work investigates the crystallization properties...
متن کاملAntimicrobial Effects of Fatty Acid Fructose Esters
Karlová T., Poláková L., Šmidrkal J., Filip V. (2010): Antimicrobial effects of fatty acid fructose esters. Czech J. Food Sci., 28: 146–149. Antimicrobial effects of various fatty acids and their esters have been extensively studied. Esters with saccharides (glucose, sucrose) have been found to have a broad spectrum of microbicidal activity. The objective of this study was to investigate the su...
