ANGULO, Ofelia  y  O'MAHONY, Michael. Food preference tests are more complex than it is thought. INCI [online]. 2009, vol.34, n.3, pp.177-181. ISSN 0378-1844.

Preference tests are widely employed for launching new products and in market studies in the food industry. Traditionally, they are applied to different products. However, the magnitude of the difference among products is not always evaluated before the preference tests are carried out. Difference tests using Thurstone model allow the estimation of the degree of difference between two products. Thus, it is of interest to know the similarities between preference tests and difference tests, so as to take advantage of the advances taking place in the latter and improve the use and application of preference tests.
