Table 3. Influence of emulsifier type on the mean droplet diameter (d ₃₂, d ₄₃) of 10 wt% canola oil-in-water emulsions (0.3 wt% emulsifier, 20 mM bis-Tris buffer, pH 7.0)

Sample	d 32	d 43
Purified surface-active substances	0.31±0.01b	0.64±0.01c
Surface-active extracts (not-purified)	0.73±0.05a	1.02±0.06b
Commercial lecithin from soybean	0.69±0.07a	2.79±0.21a

Values are mean±standard deviation (n = 3).
Means with different letters in the same column are significantly different according to Duncan’s multiple range test (p < 0.05).
