Abstract
The emulsifying and foaming properties of the 2S albumins of four cult ivars of sunflower were studied. Kinetics of flocculation creaming, re sistance to coalescence, foam formation, and stability were determined . Results obtained indicated a cultivar dependence on emulsion stabili ty. The proteins associated with emulsion stability were the most hydr ophobic, as determined by RP-HPLC, and correspond to a group of methio nine-rich 2S albumins previously characterized. Conversely to 2S album ins from other species, those from sunflower produced foams with littl e or no stability.
