PREPARATION OF FLAXSEED OIL EMULSIONS

Multiple Emulsions – Preparation and Stability

Multiple emulsions (W1/O/W2) with a long-term stability of at least 12 months were prepared in order to encapsulate low molecular weight bioactive substances (Mr < 2000 g/mol). The influence of the emulsifying procedure, i.e. the variation in energy input for dispersing W1/O in W2, and the influence of the emulsion composition were investigated in relation to emulsion stability and encapsulatio...

Improved technique for the preparation of water-in-oil emulsions containing protein antigens.

Water-in-oil emulsions are commonly used to provide persistent release of antigens necessary for sustained stimulation of the immune system. Optimal response of an animal's immune system is dependent upon repeated, maintained exposure to the antigen. The sustained release of antigen, which delays catab-olism, is thought to be one of the major methods by which adjuvants enhance the immune respon...

On the preparation of lecithin-stabilized oil-in-water emulsions by multi-stage premix membrane emulsification

Preparation and Application of Water-in-Oil Emulsions Stabilized by Modified Graphene Oxide

A series of alkyl chain modified graphene oxides (AmGO) with different alkyl chain length and content was fabricated using a reducing reaction between graphene oxide (GO) and alkyl amine. Then AmGO was used as a graphene-based particle emulsifier to stabilize Pickering emulsion. Compared with the emulsion stabilized by GO, which was oil-in-water type, all the emulsions stabilized by AmGO were w...

Thermodynamic Stability of Water-in-oil Emulsions

It is well known that colloids can show phase transitions similar to the ones observed in molecular systems. Colloid-diluted and colloid-concentrated phases can coexist in thermodynamic equilibrium at certain conditions. In a previous work, the authors of this research have used this concept to study petroleum emulsions stability, applying thermodynamic perturbation theories to calculate a phas...
