Abstract: Although TPA is one of the important methods for evaluating textural properties of fruit and vegetables, the selection of test parameters may potentially affect TPA results. The effects of compression degree and speed (in the ranges of 10% to 35% and 60 to 240 mm/min, respectively) on TPA results were investigated. Compression degree revealed remarkable influence on five textural parameters including hardness 1, hardness 2, springiness, cohesiveness and resilience, while compression speed affected only resilience. Therefore, compression degree should receive more attention in selecting test parameters for TPA measurement.

Key words: texture profile analysis, apricots, compression speed, compression degree
