Abstract
Transportation of tomatoes on farm and market roads causes interfacial stresses of tomatoes due to truck dynamics
as affected by road and transportation conditions. These stresses may affect the shelf-life of tomatoes if they are high
enough to cause damage to the fruit. This paper describes a novel method for the in situ measurement of the stresses
during actual transportation of tomatoes, providing the producer information that can assist in taking decisions regarding
the use of alternative routes, maintenance of existing routes or changes in packing to prevent excessive stresses
onto tomatoes. The process involves measurement of the stresses using a stress-sensor that is recording the interfacial
stresses continuously during transportation. These stresses can be correlated to road conditions (quantified through
standard road-roughness statistics) and used to subject tomatoes in laboratory conditions to similar stresses to study
shelf-life effects of transportation stresses. The paper focuses on the measurement process and first-order data analysis,
and excludes a detailed study on the physiological effects of the measured stresses on tomatoes.
