Nano-encapsulation of fish oil in nano-liposomes and its application in fortification of yogurt.

Fish oils have many dietary benefits, but due to their strong odors and rapid deterioration, their application in food formulations is limited. For these reasons, nano-liposome was used to nano-encapsulate fish oil in this study and encapsulated fish oil was utilized in fortifying yogurt. Physicochemical properties of produced yogurt including pH, acidity, syneresis, fatty acid composition, peroxide value as well as sensory tests were investigated during three weeks storage at 4°C.

Application of nano-encapsulated olive leaf extract in controlling the oxidative stability of soybean oil.

Our objective was to evaluate the antioxidant activity of olive leave extract (OLE) encapsulated by nano-emulsions in soybean oil. The average droplet size one day after production was 6.16 nm for primary W/O nano-emulsion and, 675 nm and 1443 nm for multiple emulsions stabilized by WPC alone and complex of WPC-pectin, respectively.

Application of image processing to assess emulsion stability and emulsification properties of Arabic gum.

This paper focuses on the development of an effective methodology to determine the optimum levels of independent variables leading to maximize stability of O/W emulsions containing Arabic gum, as a natural emulsifier and stabilizer. Response surface methodology (RSM) was employed to determine the effect of Arabic gum content (2%, 5%, and 8% (w/w)), homogenization time (5, 12.5, and 20 min) and storage temperature (4, 22, and 40 °C).
