Figure 3

Surface temperature profile of lettuce and LDPE films after PUV treatment. The surface temperatures of lettuce leaves (a) and LDPE films (b) were measured at distances of 8.8 and 4.5 cm from the UV light source, before and after 20 or 10 s exposures. Values are presented as the mean ± SE of two experiments performed in triplicate. Columns mean, bars SE.
