CALIBRATION OF THE PEA TENDEROMETER AND A COMPARISON OF TENDEROMETER READINGS FROM THREE COUNTRIES

The validity of the Texture Test System (TTS) as a reference calibration instrument for the Pea Tenderometers has been evaluated. The factors influencing the results are discussed. A linear correlation between TTS values and tenderometer units has been obtained with a correlation coefficient of at least 0.98. Calibration of the Pea Tenderometers by means of the TTS is now the standard procedure in Sweden. A comparison has been made between Swedish, English and American tenderometer readings. The results show that Swedish and English tenderometer readings are quite similar, whereas the U.S. values differ by up to 9 TU depending on the sample tenderness.
