PurposeTo establishment an objective method for detecting the brittleness of Sichuan traditional pickled cowpea.MethodThe brittleness detection was carried out with the puncture mode of the TA.XT Plus texture analyzer, and the test conditions as follows: P/2N-2 mm stainless steel needle as test probe, pre-test speed was 1.0 mm / s, test speed was 3.0 mm/s, post-test speed was 10.0 mm/s, test distance was 6 mm, trigger force was 3 g, data acquisition rate was 400 points per second，room temperature as test temperature, seedless part as testing place , chewiness as detection index.ResultThe validation test showed that chewiness value reflected the strength of brittleness objectively, and its data ranged between 100 and 500 g?sec, consisting with sensory evaluation.ConclusionThe method has the advantages of strong objectivity, high sensitivity and good stability, and can meet the need of quantitative detection of brittleness of pickled cowpea.
