Abstract: The handheld hardness tester, quality and structure analyzer and carbazole method test were used in determination of different kinds of hardness on the pickled pepper, at the same time, the sensory evaluation of pickled pepper was researched. The relevance of the sensory evaluation and the different testing methods result was further studied. To obtain the best measurement method with highly correlated to the sensory evaluation, and to provide the theory basis which could gain the optimal determination method of pickled pepper hardness. The handheld hardness tester results and carbazole method test results was not significantly negate correlation with sensory evaluation results. But through the quality and structure analyzer to measure the hardness of pickled pepper had significant positive correlation with sensory results. So using the quality and structure to measure the hardness of pickled pepper was feasible.
