Abstract

Senzorski analitičari pomoću testova razlika utvrđuju da li se dva proizvoda razlikuju jedan od drugoga ili ne. U testove razlika ubrajaju se: upoređenje u paru, duo-trio test, test u trokutu, dupli standard, A-ne-A, kao i rijeđe korišteni ABX i testovi sortiranja. Tehnike analize podataka za ove testove opisane su kao binomna, χ-kvadratna, z-, i beta-binomna distribucija. Uvidom u znanstvenu literaturu, vidljivo je da se raspravlja o utjecaju statističke snage u senzorskim testovima, o potrebi za ponavljanjem u senzorskim testovima razlika te analizi tih podataka. Svrha ovog rada bila je, pregledom znanstvene literature, iznijeti spoznaje o testovima razlika u senzorskoj procjeni hrane, kao i neke uobičajene probleme koji nastaju iz interpretacije rezultata senzorskih testova razlika.

Abstract (english)

Sensory specialist using discrimination tests to determined that two products differ from one another or not. In discrimination tests we include: paired comparison, duo–trio, triangle, dual standard, and A-not-A, as well as less used ABX and sorting tests. Data analysis techniques for these tests are described as a binomial, chi-square, z-, and beta-binomial distributions. Insight into the scientific literature, it is evident that discusses the effect of statistical power in sensory tests, the need for replication in sensory discrimination tests and the analysis of these data. The purpose of this work was, a review of scientific literature, to share knowledge on discrimination tests in sensory evaluation of food, as well as some common issues arising from the interpretation of the results of sensory discrimination tests.
