Japanese pear (Pyrus serotina var. culta "Housui") grown in Imari district of Saga prefecture has been used as specimen in the present study. The vibration test in the laboratory was carried out under identical conditions as those in high way trucks equipped with refrigeration units, which commute between Saga and Osaka. For the storage test, fruits were stored at 0, 10, and 90% relative humidity. The influence on Brix, acid, weight loss, mechanical properties and peel color were measured. Brix,m acid and mechanical properties were found to decrease with increased storage temperature and storage period. Under this condition weight loss was found to increase and peel color became darker. All of these properties significantly upon the whether they were subjected to vibration, were discriminated by the near infrared spectroscopy method
