However, the specific gravity of batter containing hydrocolloids increased slower than that of control batter as frozen treatments continued. After 4 weeks storage or 3 freezeethaw cycles, the specific gravity of hydrocolloid-containing batters was lower than that of control batter, for example, the specific gravity of control batter frozen stored for 4 weeks was 0.47 g/ml, but that of batter containing 1% CMC, 1% LBG, 1% XG were 0.39 g/ml, 0.41 g/ml and 0.43 g/ml, respectively. This observation might be ascribed to hydrocolloids which prevent the release of air from batter caused by ice crystals
