Portion size selection as related to product and consumer characteristics studied by PLS path modelling
Nguyen, Quoc Cuong; Næs, Tormod; Almøy, Trygve; Varela, Paula (Journal article; Peer reviewed, 2018)Expectations of satiation and satiety have been increasingly investigated because of the interest in how they, along with liking, can modulate portion-size selection. Consumer characteristics can also be important when ... -

PSP with trained assessors as alternative for descriptive analysis of a product with a complex sensory profile
Moelich, E.I.; Muller, M.; Kidd, M.; van der Rijst, M.; Næs, Tormod; Joubert, E. (Journal article; Peer reviewed, 2022)Rapid sensory profiling of a product over time presents a challenge in quality control, particularly when the product has a complex aroma and flavour profile. Polarized sensory positioning (PSP), based on the comparison ... -
Sample-Specific Prediction Error Measures in Spectroscopy
