Untreated and treated LWEs (54 samples) were centrifuged,
and supernatant was taken for UV–VIS measurements at 280 nm. Fig. 1
shows the UV–VIS absorbance measurements of untreated (0 min), treated LWEs at (a) 60 C, (b) 64 C and (c) 68 C for five min with a one-minute interval and the statistical differences of measurements within one temperature. The results of the ANOVA for these samples are also shown in Table 1S.
