Food analysis using artificial senses.
PublicationNowadays, consumers are paying great attention to the characteristics of food such as smell, taste, and appearance. This motivates scientists to imitate human senses using devices known as electronic senses. These include electronic noses, electronic tongues, and computer vision. Thanks to the utilization of various sensors and methods of signal analysis, artificial senses are widely applied in food analysis for process monitoring...

Green adsorbents and solvents in food analysis
PublicationGreen analytical chemistry aims to minimize the negative impact of analytical procedures on the environment and human health. This can be achieved through the use of non-toxic and environmentally friendly reagents. Classical green solvents include water, ethanol, acetone, and supercritical fluids. Water has been used for the extraction of water-soluble compounds (sugars, amino acids). Ethanol and acetone have been used for the...

Two-Dimensional Gas Chromatography Coupled With Mass Spectrometry in Food Analysis
PublicationThe development of instrumental analytical techniques provided the opportunity for in-depth characterization of many food matrices. In particular, the use of gas chromatography coupled with mass spectrometry gives impressive results in terms of quality and authenticity testing, conducting food freshness evaluations and contamination assessments. A new variant of gas chromatography, namely two-dimensional gas chromatography (GC...

Qualitative analysis of phospholipids and their oxidised derivatives – used techniques and examples of their applications related to lipidomic research and food analysis
PublicationPhospholipids (PLs) are important biomolecules that not only constitute structural building blocks and scaffolds of cell and organelle membranes, but also play a vital role in cell biochemistry and physiology. Moreover, dietary exogenous PLs are characterized by high nutritional value and other beneficial health effects, which are confirmed by numerous epidemiological studies. For this reason, PLs are of high interest in lipidomics...

Sample preparation methods used in food flavor analysis
PublicationJako, że żywność to skomplikowana matryca, a związki lotne w niej zawarte występują zazwyczaj na poziomie śladowym wymagane jest zastosowanie specjalnej procedury przygotowania próbek. W pracy zostały opisane niektóre metody przygotowywania próbek żywności, które łączą w sobie izolację i wzbogacanie analitów. Wśród opisanych metod znalazły się: PT, SPME, SDME, SBSE oraz SFE.

New analytical sample preparation techniques in food flavour analysis
PublicationIn this chapter sample preparation techniques were broadly characterized and their applications in field of food analysis were presented. Usefulness of three extraction methods: SPME, SAFE and SDE for isolation of aroma compounds from complex food matrices was compared. Additionally, requirements for sample preparation methods using in food flavour analysis were detailed.
