Shibata et al. compared the catabolism rates of octanoic acid, palmitic acid, pentadecanoic acid and heptadecanoic acid in mice using stable isotope labelling and isotope-ratio mass-spectrometry. The mice were fed 13C-labeled emulsified fatty acids and triacylglycerols. The catabolism rates were quantified from the 13C to 12C ratio in the expired CO2. The results of this straightforward study showed that while fatty acids with an even number of carbons are oxidized easily, odd-numbered fatty acids, which are relatively rare in nature, are hardly oxidized. This finding is in agreement with the previously reported results indicating that fatty acids with an odd number of carbons are more likely to accumulate in the adipose tissue than even-numbered fatty acids.

Organogelation is a hot topic in the food industry because it enables development of products with reduced levels of saturated fat. Lupi et al. present an interesting study on the stabilization of meat spreads and sauces using organogelation. Two organogelators including lecithin and monoglyceride Myverol 18-04K were compared. The effects of the organogelators were investigated by destabilizing the suspensions by centrifugation and by comparing their rheological characteristics and oil loss. The rheological approach proved to be very useful for the determination of an effective type and amount of organogelator.

Concerns about the environmental impact of chemical transformations which require large amounts of organic solvents fuel the developments of “clean” chemical processes using water instead. However, this approach is not suitable for hydrophobic substrates due to the mass transfer limitation between the aqueous and the organic phase. Boulanger et al. describe the application of mesoporous activated carbon as mass-transfer additive in rhodium catalyzed hydroformylation of unsaturated fatty acid esters in aqueous media with excellent results. The obtained oxo-products can be used in many industrial applications including the syntheses of surfactants, polymers, and lubricants.
