Table 5 also showed that all hydrocolloids caused a significant (P ? 0.05) increase in the specific volume of cake when the frozen treatment was the same. This could be related to the inhibition of these hydrocolloids on the increase in D Hm and specific gravity, the decrease in viscosity and the damage on bubbles distribution of batter caused by frozen treatments, which were discussed above. After 4 weeks frozen storage or 3 freezeethaw cycles, the biggest specific volume of cake was observed at 1% CMC.
