2-Hydroxy fatty acids (2-OH-FAs) and 3-hydroxy fatty acids (3-OH-FAs) were recently identified at trace levels in dairy products and other food samples (vegetable oils and animal brains). Due to the asymmetric carbon bearing the hydroxy group, they are chiral. This study focused on the enantioselective determination of 2- and 3-OH-FAs ...

Several Mediterranean shrubs, both autochthonous and naturalized, have been traditionally used as food, flavouring and/or spicing agents, and as phytopharmaceuticals. The interest around 'natural' and 'biological' products is steadily increasing in developed countries. Therefore, it seems reasonable to screen some shrubs with regard to the actual information about their content ...

Many food products are claimed to be effective in controlling halitosis. Halitosis is caused mainly by volatile sulfur compounds (VSCs) such as H(2)S and CH(3)SH produced in the oral cavity. Oral microorganisms degrade proteinaceous substrates to cysteine and methionine, which are then converted to VSCs. Most treatments for halitosis focus ...
