geurtests
Geurtests are sensory evaluations that focus on odors. They rely on trained human assessors to measure odor strength, quality and hedonic value, and may be complemented by instrumental methods such as electronic noses or GC-olfactometry. The main purpose is to quantify and describe odors for regulatory compliance, environmental monitoring, product development, or quality control.
The core method in geurtests is dynamic olfactometry, where a panel is exposed to controlled dilutions of
Standards and guidelines support geurtests, with EN 13725 being a prominent reference for dynamic olfactometry. Additional
Applications of geurtests are wide, including assessment of odor impact from wastewater treatment plants, landfills, and
Limitations include subjectivity and inter-individual variability among panelists, adaptation effects, and the need for rigorous training,
