16. Integration of transparency into packaging design
Master-uppsats, Lunds universitet/FörpackningslogistikSammanfattning : Transparency has become a key sales pitch for companies! It enables them to show their product and tell the consumers they do not have nothing to hide. But from a technical point of view, transparency implies many risks for product's quality such as photooxidation and other reactions leading to colour change and decrease of product's quality.

17. Critical factors for shelf life prediction of commercial fruit product
Master-uppsats, Lunds universitet/FörpackningslogistikSammanfattning : The study was carried out to identify critical factors for processed fruit shelf life in Tetra Recart packages. To investigate the importance of package volume and headspace volume, vitamin C was chosen to be the indicator. LÄS MER
18. Analysis of odourant compounds in wine : - With headspace solid-phase microextraction and gas chromatography- mass spectrometry
Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : Wine is a drink that can enhance the flavour experience of food, which is why it is important that the wine’s sensory profile is explained correctly to the consumers. In this study, headspace solid-phase microextraction gas chromatography mass spectrometry was used to characterise odourant compounds in wine to find chemical markers to explain wine sensory profiles instead of sensory analysis.

19. Methods of measuring GHG fluxes at a full-scale Swedish WWTP: : A focus on nitrous oxide, methane and carbon dioxide in the SHARON treatment
Kandidat-uppsats, Linköpings universitet/Tema MiljöförändringSammanfattning : The Stable high rate ammonia removal over nitrite (SHARON) at Nykvarnsverket in Linköping is a relatively new kind of biological treatment. Fluxes of nitrous oxide (N2O) has not been fully mapped at Nykvarnsverket and additional efforts are needed for increased knowledge about possible emissions. LÄS MER
20. Behavioural studies and collection of volatiles to identify the pheromone(s) of the great Capricorn (Cerambyx cerdo)
Kandidat-uppsats, SLU/Dept. of Plant Protection BiologySammanfattning : This work was aimed at identifying the pheromone component(s) of the great Capricorn longhorn beetle (Cerambyx cerdo). Volatile samples from beetles were obtained by means of collection of headspace volatiles from the animals, and by direct solvent extraction of body parts, and analysed by gas chromatography-mass spectrometry (GC-MS) and gas chromatography- Electroanntennography (GC-EAG).
