Novel products produced from seed oil materials (TAG, phospholipids, and minor components such as tocopherols, sterols, stanols, and fatty acyl esters of the latter two) by enzyme-mediated purification or chemical modification are reviewed. The primary focus is on "value-added products" of current and potential use (particularly in the food, cosmetics, and pharmaceutical industries) that require the selectivity of enzymes and mild operating conditions, the latter being beneficial for polyunsaturated and oxygenated acyl groups. The paper briefly reviews the biochemistry of enzymes in lipid modification (lipases, phospholipases, and lipoxygenases) and discusses and assesses the current and future applications, current state of the art, and areas for future research for the following enzyme-mediated processes: isolation of polyunsaturated and oxygenated FFA; formation of structured TAG as nutraceuticals; formation of MAG, saccharide-FA esters, and other polyhydric alcohol ester as emulsifiers and surfactants; isolation and/or modification of tocopherols and sterols as antioxidants; formation of hydroperoxides as chemical intermediates; and modification of phospholipids for use in liposomes.

    The diacylglycerols (DAG) are emulsifiers with high added value used as functional additives in food, medicine, and cosmetic industries. In glycerolysis of oils for the production of DAG, the immiscibility between the substrates (glycerol and oil phases) has to be overcome, for example, by the...

    Background: Fatty acids are precursors in the synthesis of surfactant phospholipids. Recently, we showed expression of apolipoprotein C-II (apoC-II), the essential cofactor of lipoprotein lipase (LPL), in the fetal mouse lung and found the protein on the day of the surge of surfactant synthesis...
