ABSTRACT
Conjugated linoleic acid contains unsaturated fatty acids with multiple bioactivities, but it has poor oxidative and physical stabilities. Its emulsion was fabricated with glycosylated whey protein isolate and hydrolysates of glycosylated whey protein isolate to enhance its stability. An obvious decrease in peroxide value, thiobarbituric acid-reactive substances, particle size and creaming index of emulsion loaded by hydrolysates of glycosylated protein isolate with the increase of hydrolysis time. However, the absolute value of zeta-potential and interfacial adsorption rate of emulsion stabilized by hydrolysates of glycosylated whey protein isolate, were increased by 10.99 and 16.94% at hydrolysis time of 120 min, compared with emulsion loaded by glycosylated whey protein isolate. Thus, limited hydrolysis of glycosylated whey protein isolate as an effective method, remarkably improved the oxidative and physical stability of emulsion.
