3.4. Color properties of surimi gels
Table 4 shows the tristimulus color values (L*, a*, and b*), and
whiteness of surimi gels. Incorporating between 2 and 8 g/100 g oat
bran, lightness (L*) showed palpable decreases (P < 0.05). The
addition of oat bran to surimi, in all treatments, resulted in more
negative a* values, indicating a slightly greater green hue in these
treatments. It was found that with incorporating oat bran proportionally
from 2 to 8 g/100 g, while lightness decreases with
increasing greenness and yellowness, the overall whiteness of the
surimi samples decreases. However, no difference (P > 0.05) was
observed by addition of 6 and 8 g/100 g of fiber. The increase in
yellow color of the samples could be contributed to the carotenoid
pigments present in oat bran (Yılmaz & Daglıoglu, 2003). These
results tended to agree with the report of Yılmaz and Daglıoglu
