Fig. 7). The ice creams
made with NFDM and WPI and the ice cream made with NFDM and
procream at 8% protein had mean air cell sizes, ranging between
31.5 and 35.2 mm, significantly higher than the control ice cream.
Higher levels of surface-active components (proteins, emulsifiers,
etc.) generally promote smaller air bubbles. This trend was not
observed in either the ice creams containing single protein sources
or the protein blends
