Minimizing carryover effects in triangulation tests is crucial to ensure that the results accurately reflect the panelists' sensory evaluations of the samples being tested. Mixing up the order sequence of samples is an effective method to achieve this, as it helps prevent bias that may arise from the order in which the samples are presented.

When panelists evaluate samples in the same order every time, they might subconsciously compare samples based on their preceding experiences, which can skew their perceptions and lead to carryover effects. By varying the sequence in which samples are presented, each trial is less likely to be influenced by previous evaluations, thus allowing for a more objective assessment of each sample's sensory characteristics.

This approach helps maintain the integrity of the test, as it minimizes the chance that one sample may favorably or unfavorably affect the evaluation of another based solely on their placement within the sequence.
