temperature and barrier materials (Yu and others 2007). The water solubility ofbeta-cyclodextrin increased with increasing temperature (Astray and others 2009). It could be presumed that higher temperature < ()0 °C would be helpful to the reaction between 2 chemicals composed of barrier materials. Such a reaction results in an apparent change m the emulsion viscosity. The influence of high emulsifying temperature (> 70 °C) on emulsion viscosity is simply a physical effect. That is to say, viscosity decreases as temperature rises. Moreover, high emulsifying temperatures (60 to 70 °C) might disrupt the affinity of the barrier materials to each other and result in lower emulsion stability. However, emulsify
