HAMBURG SCHOOL OF FOOD SCIENCE

The HAMBURG SCHOOL OF FOOD SCIENCE (HSFS) was founded in 2011 by Markus Fischer. The orientation of the HSFS is interdisciplinary and is characterized by the combination of classical food chemistry questions with modern biochemical / nutritional diagnostics amazon prime video film herunterladen. In the food sector, we mainly work on the development of analytical methods for the authenticity and quality control of food. In addition to methods for “in-field” analysis, we are interested in methods for routine applications, as well as technically very sophisticated fingerprinting methods herunterladen.

Food fraud is an increasingly critical issue in the very complex and global food supply chain. Consumers are deceived on the one hand, but so are honest food operators Download old pc games for free. Among the most relevant issues is the verification of the geographical origin and botanical identity of food raw materials.

By experimentally capturing all relevant molecular levels in a cell using classical omics technologies, which include genomics, proteomics and metabolomics, as well as the additional correlation of elemental analyses (isotopolomics), we create a system-wide and tamper-proof FOOD PROFILE of a sample and can thus unequivocally determine its authenticity siren to.

Our work is divided into the following areas: i.) The development of high-tech methods with the aim of obtaining high-resolution data (maxi-fingerprint) to extract the differences between different groups of samples wie kann man bloons td 5 herunterladen. ii.) The subsequent development of routine applications based on the identified differences (mini-fingerprint). iii.) The transfer of the developed protocols to other matrices and scientific questions whatsapp downloaden apple.

In order to address these issues, we are equipped with state-of-the-art analytical instruments. In the field of genomics, for example, we have the latest Next Generation Sequencing (NGS) technologies (MiSeq, Illumina; MinION, Oxford Nanopore Technologies) kalender mit feiertagenen. For the field of metabolomics, we mainly work with a high-resolution LC-MS unit (6560 Ion Mobility (IM) Q-TOF LC/MS, Agilent) and for the field of isotopolomics with various ICP-MS instruments coupled to an ablation laser (HR-ICP-MS Element2; ThermoFisher Inc.; ICP-Q-MS Agilent 7700x, Agilent Technologies Inc.; NWR 193, ESI) adventsbilder kostenlos herunterladen.

In addition to high-resolution technologies, near-infrared (NIR) spectroscopy in combination with chemometric evaluation methods has proven to be a very useful and comparatively simple method for the authentication of food raw materials

Below is a selection of publications that have been produced as part of the CNFP autogenes training zum downloaden.
