Abstract
Emulsions are thermodynamically unstable systems. In order to enhance the kinetical stability, monodisperse emulsions with small particle size are desirable. However, the conventional emulsification processes, such as the high-pressure homogenizers, do not allow controlling the drops diameter precisely. Besides, high energy input is necessary to promote shearing, break-off and formation of the drops. The high consumption of energy results in higher costs and in degradation of heat-sensitive compounds at high pressure conditions. Furthermore, regarding the multiple emulsions, in which one emulsion is dispersed in another emulsion, the high shear stress may result in the emulsion destabilization caused by the internal drop rupture. The use of microchannels for emulsification has the advantage of forming less polydisperse drops at low energy input. However, this technology is new and has not been fully explored yet, mainly with complex components, such as food ingredients. Thus, this study aims to evaluate the emulsification by microchannels comparing to a conventional method, the high-pressure homogenization. The effect of operating conditions and the different geometric characteristics of microchannels in the emulsification will be evaluated, as well as the formation of food-grade simple and multiple emulsions by microchannels.
