Using a Virtual Store As a Research Tool to Investigate Consumer In-store Behavior Kunalai Ploydanai1,2, Jos van den Puttelaar1,3, Erica van Herpen1,2, Hans van Trijp1,2 1Wageningen University and Research, 2Marketing Consumer Behaviour Group, 3Wageningen Economic Research This paper describes the use of a desktop virtual store to create virtual shopping environments to investigate in-store consumer behavior. A description of the protocol to build and run experiments, example results from an experiment concerning store layout, and important considerations when conducting virtual store experiments are presented.
Analysis of Fatty Acid Content and Composition in Microalgae Guido Breuer1,2, Wendy A. C. Evers1,2, Jeroen H. de Vree1,2, Dorinde M. M. Kleinegris2,3, Dirk E. Martens1,2, René H. Wijffels1,2, Packo P. Lamers1,2 1Bioprocess Engineering, Wageningen University and Research Center, 2AlgaePARC, Wageningen University and Research Center, 3Food and Biobased Research, Wageningen University and Research Center A method for the determination of fatty acid content and composition in microalgae based on mechanical cell disruption, solvent based lipid extraction, transesterification, and quantification and identification of fatty acids using gas chromatography is described. A tripentadecanoin internal standard is used to compensate for the possible losses during extraction and incomplete transesterification.
