| Abstract | Transport of tomatoes from farming areas to the different markets in the Bangkok area results in considerable mechanical damages due to the methods of handling a nd transport condition s. Mechanical damage in tomatoes, due to the vibration and impact effects was experimental ly done to compare the damages in 2 types of containers, bamboo and plastic baskets, and the 3 conditions of cushioning. In the vibration effects, performed by using a constructed vibrating table, the variables were frequencies and amplitudes, while in the impact effects, the variables were the number of drops and the drop heights. In the overall analysis, there was no significant difference between container types in the vibration tests while the impact tests gave significant effect by the container types. Prior to the above bulk tests, the physical properties of the individual tomatoes were determined in terms of firmness and maximum loading by means of compression tests. Significant differences among the tomato maturities were detected. The green stage of maturity was found to have the highest resistance to compressive loads. |
