RESULTS AND DISCUSSION
Figure 1 shows the cumulated reflectance spectra of the tomato juice samples. The four varieties have similar spectra
with two reflectance peaks identified around 1080 and 1280 nm. The typical absorption bands related to the high
water-content of tomato samples can be seen around 980 (Flores et al., 2009), and two sugar-related peaks appear
also in the spectrum around 1200 and 1410 nm. Similar absorption bands were reported in the studies of apricot,
tomato, and passion fruit (Oliveira, 2014).
