Agricultural losses can be defined as reductions in the physical quantity of product available for consumption, often with a concomitant decrease in quality, reducing the product's commercial or nutritional value. In addition to extremely high quantitative losses is the product's qualitative loss, which reduces its life, its nutritional properties and commercial value, and its organoleptic attributes. The dimension of lesions is another aspect that affects the two types of losses and that can alter the product's lifetime. Healthy fruits (control) and fruits subjected to mechanical injury were used. These injuries were caused by perforation to produce a lesion in a few cells and up to many cells, using cylindrical stainless steel objects of different diameters (0.4, 0.8, 1.5, 3.5, 6.5 and 12.2 mm). The objective of this work was to evaluate the effect of the size of the injury on the respiration of tomatoes during storage. The size of the injury caused increased respiration of ripe tomato fruits. The fruits subjected to injuries with dimensions of 6.5 and 12.2 mm showed a significant increase in respiration starting from the fifth day of storage. Firmness decreased during storage, with the most pronounced decrease occurring in fruits subjected to 12.2 mm injuries. Source
