The specific volume was the most important physical property of cakes because of its determination on consumer preferences. Table 5 indicated how the specific volume changed as frozen treatments changed as hydrocolloids were added. Whether cake contained hydrocolloids or not, a significant (P ? 0.05) decrease in specific volume was present as frozen storage time and freezee thaw cycles increased, and the freezeethaw cycles appeared to give
all cakes a more significant decrease in specific volume. These results might be due to the increase in the batter specific gravity and deterioration of bubbles distribution caused by ice crystals grown up during frozen storage.
