A comparison of generalised procrustes analysis and multiple factor analysis for projective mapping data

Tomic, Oliver; Berget, Ingunn; Næs, Tormod (Peer reviewed; Journal article, 2015)

Generalised procrustes analysis and multiple factor analysis are multivariate statistical methods that belong to the family of multiblock methods. Both methods are often used for analysis of data from projective mapping ...

A comparison of methods for analyzing multivariate sensory data in designed experiments - A case study of salt reduction in liver paste

Næs, Tormod; Tomic, Oliver; Greiff, Kirsti; Thyholt, Kari (Peer reviewed; Journal article, 2014)

This paper presents a comparison of different methods for analyzing designed experiments. The methods used are based on PCA, PLS and ANOVA, used either separately or in combination. Special emphasis will be on how to obtain ...

A comparison of two new take-away strategies and their relation to rating and ranking of extrinsic properties of dry cured ham

Næs, Tormod; Monteleone, Erminio; Segtnan, Anne; Hersleth, Margrethe (Peer reviewed; Journal article, 2013)

This paper is a study of the relationship between rating, ranking and take-away choices of dry cured ham. Extrinsic attributes related to country of origin, ageing time and price are considered and we study average population ...

A discussion of recent methodologies for combining sensory and extrinsic product properties in consumer studies

Asioli, Daniele; Varela, Paula; Hersleth, Margrethe; Almli, Valerie Lengard; Olsen, Nina Veflen; Næs, Tormod (Journal article, 2016)

Understanding the interaction of sensory and extrinsic product attributes in consumer preferences has been identified as one of the key pillars for raising the likelihood of food products’ success in the market. Over the ...

Application of sequential and orthogonalised-partial least squares (SO-PLS) regression to predict sensory properties of Cabernet Sauvignon wines from grape chemical composition

Niimi, Jun; Tomic, Oliver; Næs, Tormod; Jeffery, David; Bastian, Susan E.P.; Boss, Paul K. (Journal article; Peer reviewed, 2018)

Combining analysis of variance and three-way factor analysis methods for studying additive and multiplicative effects in sensory panel data

Romano, Rosaria; Næs, Tormod; Brockhoff, Per Bruun (Peer reviewed; Journal article, 2015)

Data from descriptive sensory analysis are essentially three-way data with assessors, samples and attributes as the three ways in the data set. Because of this, there are several ways that the data can be analysed. The ...

Common and distinct components in data fusion

Smilde, Age K.; Måge, Ingrid; Næs, Tormod; Hankemeier, Thomas; Lips, Miriam B.; Kiers, Henk A. L.; Acar, Evrim; Bro, Rasmus (Journal article; Peer reviewed, 2017)

In many areas of science, multiple sets of data are collected pertaining to the same system. Examples are food products that are characterized by different sets of variables, bioprocesses that are online sampled with ...

Comparison of different clustering methods for investigating individual differences using choice experiments

Development of enzyme cocktails for complete saccharification of chitin using mono-component enzymes from Serratia marcescens

Mekasha, Sophanit; Byman, Ida Roksvåg; Lynch, Catherine; Toupalová, Hana; Andera, Ladislav; Næs, Tormod; Vaaje-Kolstad, Gustav; Eijsink, Vincentius Gerardus Henricus (Peer reviewed; Journal article, 2017)

One potential strategy for biorefining of chitin-rich biomass entails enzymatic saccharification, which, so far, has been scarcely explored. Here, saccharification of chitin was explored using response surface methodology ...

Different liking but similar healthiness perceptions of rye bread among younger and older consumers in Sweden

Sandvik, Pernilla; Nydahl, Margaretha; Marklinder, Ingela; Næs, Tormod; Kihlberg, Iwona (Journal article; Peer reviewed, 2017)

Rye breads, especially those with a chewy texture and sour flavor, have shown several health benefits but their consumption is lower among younger consumers than older. This study explores liking of commercial rye bread ...
