Before fermentation, the viscosity of the beverage made with oat
flakes was 119.22 ± 3 Pa∙s. Following fermentation, it decreased for
all the beverages. The viscosity of LP09-OFB was lower (ca. 32%) than
that of Ct-OFB., The viscosity of E-OFB further decreased (Table 3). The
chromaticity co-ordinates L, a, and b of Ct-OFB were 73.44 ± 0.13,
1.66 ± 0.05 and 14.42 ± 0.02, respectively. Compared to Ct-OFB, the
fermented beverages had slight but significantly (P b 0.05) higher
values of lightness (L) (76.82 ± 0.25 and 76.62 ± 0.12 for LP09-
OFB and E-OFB, respectively), and lower values of a (1.37 ± 0.02,
and 1.45 ± 0.02) and b (13.04 ± 0.03 and 13.06 ± 0.02). Color differences
(ΔE) are reported in Table 3.
