To determine the impact of IR heating on tomato skin, changes in biomechanical properties of tomato skin before and after IR heating were investigated using two mechanical tests, the skin adhesive test and the uni-axial tensile test of failure. The former test quantified the degree of peel loosening induced by IR heating, and the latter test reveals the mechanical behavior of tomato skin after IR heating. Comparisons were carried out on fresh tomatoes and the tomatoes subjected to 60 s IR heating for the two tomato cultivars. The average values of 10 fruits for each treatment are reported with outliers removed.
