2.4. Specific gravity of batter
The specific gravity (SG) of the raw batter was determined
according to Ashwini, Jyotsana, and Indrani (2009). The SG was
calculated gravimetrically as the ratio of the weight of a known
volume of batter to that of the weight of an equal volume of water
at 28 ± 2 C using a standard container of known volume. The
measurements were made in triplicate for different batches of each
formulation.
