  1. 1. Development of an analytical method for the screening of meaty flavors in commercial foodstuff by SPME-GC/O-MS

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Ioannis Protopappas; [2021]
    Keywords : Gass Chromatography; Mass spectrometry; Meaty flavors; Aromas; Solid pahse microextraction; Mallaird; Lipid degradation; Food technology; Agriculture and Food Sciences;

    Abstract : The aim of the project was to develop a methodology for the chromatographic analysis able to identify the key odorants in meaty food products. The approach was based on the analysis of an already in market product and the theoretical background of the meaty flavors sensorially. READ MORE

  2. 2. Development of headspace solid phase microextraction gas chromatography mass spectrometry method for analysis of volatile organic compounds in board samples : Correlation study between chromatographic data and flavor properties

    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Author : Thea Zethelius; [2021]
    Keywords : Solid phase microextraction SPME ; method development; volatile organic compounds VOCs ; food contact material FCM ; flavor experience; design of experiment DoE ; multivariate analysis;

    Abstract : The purpose of this thesis work was to develop a headspace solid phase microextraction gas chromatography mass spectrometry (HS-SPME-GC-MS) method to detect volatile organic compounds (VOCs) in board samples and to statistically investigate potential correlation between chromatographic data and flavor data obtained from a trained panel. The developed method would hopefully serve as a complement to the already established routine analyses at Stora Enso and gain an increased understanding of which VOCs in the board influence its flavor properties.

  3. 3. SPME Method for Chemical Analysis of Heavy Organic Trace Compounds in Synthesis Gas

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Constancia Felise Elemia Freire; Simon Edin; Chang Ho Lee; [2020]
    Keywords : ;

    Abstract : There currently exists no commercialized method for rapid sampling and analysis of trace tar ingas streams. Solid phase microextraction (SPME) with a polydimethylsiloxane (PDMS) solidphase has been previously investigated as a possible candidate due to its solvent-free natureand reusability. READ MORE
