“…3). The spectrum revealed a characteristic absorption peak at wavelength of 331 nm, which can be assigned to the intrinsic band-gap absorption of CeO 2 -NPs due to the electron transitions from the valence band to the conduction band (O (2p) to Ce (4f) in CeO 2 -NPs) [31,32]. The good absorption of the CeO 2 -NPs in the UV region proves the applicability of this material in such biomedical application such as sun-screen protectors or antiseptic in ointments.…”

“…The procedure for measuring viscosity has been described in previous studies (34). The zeta potential was measured using un Zetasizer Nano ZS90 (Malvern Instruments Ltd.,Worcester, UK) (35) and to avoid multiple dispersion effects and air bubbles presence, emulsions were diluted with deionized water in an emulsion: water ratio (1: 100). The stability index (SI) is based on the light scattering properties, which is related to the average droplet size and wavelength.…”

Background: Guacamole is a sauce or dressing composed of avocado pulp and other ingredients. Guacamole powder is an important advance in the generation of value added for the avocado chain, as it is an alternative product with the potential to be used by the final consumer. Objectives: The aim of this study was to standardize the spray drying process for guacamole powder using the response surface methodology. Methods: Four independent variables were taken into account for the experiment design: atomizing disk speed (ADS), air inlet temperature (AIT), air outlet temperature (AOT) and vacuum pressure (VP). In addition, the following dependent variables were considered: water activity (a w ), moisture (Xw), solubility (S), hygroscopicity (H), color (L

“…The zeta-potential is the electrical potential at the "shear plane" which is defined as the distance away from the droplet surface below which the oppose-ions remain strongly attached to the droplet when it moves in an electrical field [35]. In other words, the droplet surface charge is considered by measuring zeta potent.…”

Gum tragacanth (GT) exuded from an Iranian Astragalus species was γ-irradiated at 0, 0.75, 1.5, 3, 5, 7, 10 kGy and used to stabilize a model oil in water emulsion system. Stability and physicochemical properties of emulsion samples were investigated with respect to the effect of irradiation treatment on functional properties of gum tragacanth.Particle size distribution, interfacial tension, zeta potential, steady shear and oscillatory rheological measurements were used to characterize and evaluate the emulsion samples and obtain more information about the possible stability mechanism. Emulsions were prepared by homogenizing 10% w/w sun flower oil with 90% w/w aqueous gum dispersions and stored quiescently at 25ºC for 120 days. Results indicated that using 1.5 kGy irradiated GT was more effective in providing optimum values of apparent viscosity, number mean diameter, electrosteric repulsion and structure strength for getting maximum emulsion stability. GT significantly reduced the interfacial tension of the oil and water system, but no significant differences were observed among all irradiation treated and non-irradiated samples. This study revealed that, GT acts as a bifunctional 2 emulsifier and irradiation treatment has a great positive influence on its ability to reduce droplets collision frequency and stabilize oil in water emulsion.
