fat content did not affect initial particle
size at similar protein-to-fat ratios, particle size was
plotted against protein-to-fat ratio. Increasing the
protein-to-fat ratio led to a rapid decline in d4,3, irrespective
of the whey protein material used in the
system. Thus, whey proteins in WPF and b-LGI were
very effective in covering fat surfaces and consequently, in
inhibiting immediate coalescence. Similar results were
observed by Klemaszewski et al. (1992) for emulsions
(40% peanut oil-in-water) prepared with pure whey protein
material (b-lg, a-la and BSA) and by Agboola and Dalgleish
(1995) for emulsions (20% soya oil-in-water) prepared
with b-lg.
