The duration of whipping also influenced the foam expansion, it is observed from the table 1 that the foam expansion increased with increased in whipping time.
The egg albumin stabilized foams exhibited maximum upto 15 min of whipping and thereafter a considerable decrease in foam expansion was noticed.
(2006) also reported that expansion of foams increased with whipping time up to a maximum and decreased thereafter probably because excessive whipping (overbearing) could cause foam to collapse.
