Comparison of oil-in-water emulsions prepared by ultrasound, high-pressure homogenization and high-speed homogenization.

ABSTRACT: This study was designed to compare the properties of myofibrillar protein (MP) stabilized soybean oil-in-water emulsions fabricated by ultrasound-assisted emulsification (UAE), high-pressure homogenization (HPH) and high-speed homogenization (HSH). The emulsion properties, droplet characteristics, interfacial proteins, protein exposure extent, microrheological properties, multiple light scattering results, and 7 d storage stabilities of the three emulsions were specifically investigated. Our results indicate that UAE and HPH were better emulsification methods than HSH to obtain high-quality emulsions with higher emulsifying activity index (UAE 20.73 m²·g^-1, HPH 11.76 m²·g^-1 and HSH 6.80 m²·g^-1), whiteness (UAE 81.05, HPH 80.
