Tomatoes are listed as the most consumed vegetables around the world, with a profitable market into the peeled-canned tomato industry. In this sense, the lye method is commonly performed as peeling method, but with severe impact on the environment. Therefore, this study focuses on modifying the surface of tomato skin by using laser CO2 drilling under different pore size (127.92-194.39 mu m), pore density (2-9 pore.cm(-2)) and coupled with moderate electric field (MEF) at 1333 V m(-1) to facilitate its removal. The variables NaOH concentration, pore density and pore size were tested. As a result, the effective diffusion coefficient for the drilled skin ranged between 4.45 x 10(-11) and 24.95 x 10(-11) m(2) s(-1) at 60 degrees C (p-value < 0.05). Likewise, a decrease in total work, peak load and Young's modulus was noticeable compared to conventional treatment (p-value < 0.05). Therefore, the laser CO2 drilling might improve the skin removal with less energy and lower NaOH concentration compared to conventional treatment.
