Consumer tests are classified in terms of the location of testing as laboratory tests or central location tests (CLTs) and home use tests (HUTs). CLT is generally used in sensory tests due to the ease of test control, whereas HUT has higher validity because of real consumption. However, the lack of test control in HUT is a major issue. In order to investigate the error occurrence and efforts required to minimize errors, three groups of tests were designed differing time and order control and evaluation was conducted using six snacks with texture differences. Errors related to time, order, and consumer or sample number were higher for more controlled conditions, however, most errors were recoverable using identification information except for cases of no response. Additionally, consumers preferred to consume all snacks in the evening at home, which differed from the typical 9 a.m. to 6 p.m. evaluation time in CLT. However, the timing differed for consumers with self-reported snacking time. The research title that included the term ‘home’ might have influenced the participants’ choice of location for evaluation. Overall, there was no significant difference between the results of groups despite different time and order controls, which could increase the applicability of HUT.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
