referenssmaker

Referenssmaker are standardized reference taste samples used in sensory science to calibrate and train tasters and to anchor evaluation scales during taste testing. They provide a consistent benchmark that allows product samples to be compared reliably across sessions, panels, and laboratories.

They are typically used in panel training, product development, and quality control. Referenssmaker are prepared under controlled conditions in neutral matrices to minimize interference from texture or aroma. Common references include basic tastes such as sweet (sucrose solution), sour (citric acid), salty (sodium chloride), bitter (quinine sulfate), and umami (monosodium glutamate). Depending on the protocol, aromatic or more complex references like vanilla, lemon, or coffee can also be employed to calibrate aroma-taste perception.

Preparation and protocol for referenssmaker are defined by calibration standards and validated training procedures. Samples are coded and presented in a randomized order, with palate cleansers provided between samples. Panelists rate intensity and other attributes using anchors tied to the references, aiding consistency in scoring and interpretation.

Training and application: during initial training, panelists learn to recognize reference intensities and apply scales consistently. Ongoing checks such as discrimination tasks and reproducibility assessments help maintain panel performance over time. Referenssmaker are used to align evaluators, support product comparisons, and improve quality control, especially in multi-site studies or large-scale sensory programs.
