In the last few years there has been a tremendous development in the classical questions with regard to determination of molecular mass, identification amino acid sequence and structure of proteins. With these technical improvements, it is becoming more and more interesting to characterize the changes involved in proteins embedded in the food matrix as a result of their technological processing, especially in terms of the influence on their functional, nutritional and phsiological properties. Many such posttransational protein modifications occuring due to reactions with other food constituents (e.g. secondary plant metabolites) provide a series of possible fields for application of a sample preparation with a soft ionisation technique using mass spectrometry. The matrix assisted laser desorptions/ionisation ? time of flight ? mass spectrometry (MALDI-TOF-MS) and the surface enhanced laser desorptions/ionisation ? time of flight ? mass spectrometry (SELDI-TOF-MS) have become since than two of the most important methods of choice for solving of such questions and these both techniques have been described here with correponding examples.}, language = {de} } @article{KrollRantersRaweletal.2004, author = {Kroll, J{\"u}rgen and Ranters, Holger and Rawel, Harshadrai Manilal and Rohn, Sascha}, title = {Isoflavones as constituents of plant foods : Isoflavone als Bestandteile pflanzlicher Lebensmittel}, year = {2004}, abstract = {Vor dem Hintergrund der Diskussion {\"u}ber die ern{\"a}hrungsphysiologische Bedeutung von Isoflavonen befasst sich die vorliegende {\"U}bersichtsarbeit auf der Basis von 186 Literaturquellen mit der Struktur, dem Vorkommen, der Aufnahme, der Biosynthese, der Resorption, dem Metabolismus und der biologischen Wirkung dieser Untergruppen der Pflanzenphenole.
