Colour attributesThe colour attributes results of fingers showed an obvious significant effect between treatments (P 0.05) than the frozen storage period (Table 2). To be more specific, the L* and a* values of both Tsp and Tc were significantly higher than those of Tsw during the whole storage, whereas the b* values of Tsw were higher than those of Tsp and Tc (P 0.05). Gines et al. (2004) reported that not only muscle structure characteristics but also pigment concentrations affect the colour. Therefore, such changes in the colour attributes of Tsw can be ascribed to the seaweed pigments as chlorophylls, betacarotene and xanthophylls, which contributed in the darkening of Tsw. seaweed pigments as chlorophylls, betacarotene and xanthophylls are ascribed to the the darkening of Tsw. Choi et al. (2012) observed similar results in pork patties incorporated with L. jacopina powder.
