[obsah] => DEPARTMENT OF FOOD ANALYSIS AND NUTRITION is a part of the Faculty of Food and Biochemical Technology. The research projects are mainly focused on food and feed quality, authenticity & safety related issues; investigations concerned with the impact of environmental conditions on the human food chain are also included. Special attention is paid to studies concerned with food components interactions / breakdown which may result in changes of nutritional value and/or sensory properties. In the recent years, interdisciplinary ‘omics’-based research aimed at the assessment of in vivo / in vitro effects induced by biologically active compounds, both beneficial and toxic, has been initiated.

[obsah] => - Nicolet iS50 FT-IR Spectrometer (Thermo Fisher Scientific, USA)
Description
Fourier transform infrared spectrometer Nicolet TM iS50 (FTIR)
This instrumentation represents Fourier transform infrared spectrometer (FT-IR) with a built-in diamond ATR crystal for measurements using an attenuated total reflection technique. Measurements can be performed in UV-VIS, IR, NIR, and FAR area (without the need of blowing through the device). The instrument is also able to record Raman spectra without any replacement of the system components. Infrared spectroscopy is widely used in both qualitative and quantitative analysis. At the Department of Food Analysis and Nutrition UCT Prague, this instrument is mostly used for determination of the acid value or authentication of various foodstuffs and food supplements (such as oil, butter, margarine, spices, honey, lecithin, oyster mushroom, milk thistle).

- FCPC® A Kromaton (Rousselet Centrifugation)
Description
Fast centrifugal partitioning chromatography FCPC® A Kromaton coupled with peripheral system puriFlash®4250 (Interchim)
This instrumentation consists of a fast centrifugal chromatography (FCPC® A Kromaton) with a rotor volume of 1000 ml and a peripheral system puriFlash®4250 (Interchim), which includes a pump, injection valve, 50 ml injection loop, PDA detector (200 – 600 nm) and fraction collector. The separation is based on the different affinity of the analytes to the two immiscible solvent mixtures, which represent the stationary and mobile phase. The system is suitable for the separation and isolation of various bioactive compounds, such as phenolics, flavonoids, lignans, alkaloids, and many others.
Main benefits of the FCPC® A Kromaton system
• Large amounts of sample mass can be loaded (up to 50 ml)
• No extraction and purification of target molecules needed prior FCPC
• Suitable even for low-concentrated bioactive compounds • Applicable for a broad spectrum of compounds
At the Department of Food Analysis and Nutrition UCT Prague, this instrument is mainly used for the separation and isolation of bioactive compounds from Cannabis sativa L. extracts.
- Halogen Moisture Analyzer HG63 (Mettler Toledo)
Description
The halogen moisture analyzer is suitable for routine determination of moisture content. It is fast (results obtained within minutes) and efficient, and offers very good repeatability even if a small amount of sample is available. The fast speed and good repeatability of the measurement are achieved by a circular halogen lamp and a gold-plated reflector. The results are obtained with resolution of up to 10 ppm MC. The halogen moisture analyzer is mainly used for the determination of the dry matter in plant material.
