✦ Synopsis

Alphaltenes were selected on the basis of their capacity to form water-oil emulsions. They were characterized by electron microscopy, surface group analysis, g.p.c. and low-angle X-ray scattering. It appears that the high stability of water-oil emulsions is related to the 'structuring' capacity of asohaltenes at the water-oil interface. Some asDhaltenes are able to form regularly stacked layers, resembling the behaviour of surfactant liquid crystals.

Asphaltenes which differ in their abilities to form water/oil emulsions were analysed by acidimetry, infrared and nuclear magnetic resonance spectroscopies. Asphaltenes which easily form such emulsions are loosely packed molecules and exhibit a marked acid/base imbalance.

This work investigates the fundamental properties of emulsiÐers that may contribute to the fat-associated sensory attributes of emulsions. Model oil-in-water emulsions were prepared with 0, 12, 24, 36 and 48% oil and emulsi-Ðed with seven di †erent emulsiÐers ; two proteins ; sodium caseinate and wh
