Preparation of O/W Emulsions by High Pressure Homogenizer

Homogenizer Handbook Processing of Emulsions and Dispersions

2 From its very genesis APV has maintained an impeccable reputation for excellence worldwide. That standard is perpetuated in the field of homogenization and high pressure pumps. It's a tradition that dates back to our invention of the homogenizer in the early 1900's. That desire to excel in saving our customers is demonstrated today through innovative design, precision, engineering, quality ma...

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...

Numerical Analysis of Severe Plastic Deformation by High Pressure Torsion

High-pressure torsion (HPT) is a metal processing method in which the sample is subjected to a very high plastic shear deformation. This process can produce exceptional levels of grain refinement, and provides a corresponding improvement in mechanical properties. To investigate the stress and strain distribution due to HPT process finite element simulation were conducted to investigate effectiv...

O/W emulsions stabilized by whey protein: Influence of heat treatment and high pressure homogenization

The objective of this work was to study the physical properties of O/W emulsions stabilized by whey proteins. Coarse emulsions were prepared with 30% (w/w) soy oil and water phase containing 7% w/w of non heated and denatured whey proteins at 70 or 90oC. These emulsions were high pressure homogenized at 250, 450 and 600 bar in order to obtain fine emulsions. Creaming kinetics of the emulsions o...
