Abstract

In this study, the effect of heteroaggregation (HA) on the physicochemical stability and the formation of volatile substances of DHA emulsions was investigated. HA-DHA emulsions were produced by combination of lactoferrin (LF)-DHA and soy protein isolate (SPI)-DHA emulsions at pH 6.0. Zeta-potentials, droplet sizes, stability, and microstructures were measured as a function of different ratios of LF-DHA to SPI-DHA droplets. DHA oxidation of single and HA emulsions was determined through measurements of lipid hydroperoxides, thiobarbituric acid reactive substances, and the formation of volatile substances. LF-DHA to SPI-DHA droplets ratios of 5:5, 4:6, and 3:7 formed stable emulsions. The lowest zeta-potential, biggest droplet size, and optimum physical stability of heteroaggregated emulsion occurred at a 5:5 of LF-DHA to SPI-DHA droplet ratio. Microstructure behavior indicated that the HA emulsions (LF-DHA droplets/SPI-DHA droplets = 5:5) formed specific three-dimensional uniform networks. The formation of thiobarbituric acid reactive substances, lipid hydroperoxides, and volatile compounds including hexanal and ( E, E)-2,4-heptadienal decreased in HA compared to single emulsions. The results indicated that the physicochemical ...Continue Reading
