Esta Tesis Doctoral es una contribución a los avances en formulación y procesado de emulsiones de aceites esenciales con diámetros medios de gota submicrónicos, utilizando un nuevo tensioactivo derivado de la biomasa del trigo. Se han preparado emulsiones de aceite de tomillo y romero mediante la técnica de homogeneización por microcanales,...

ACKGROUND: Nowadays, it is of great interest to develop stable and sustainable formulations that act as nanocarriers of active ingredients. In this work, the droplet size distribution, rheology and physical stability of nanoemulsions with improved properties containing rosemary essential oil and biopolymers as a function of the concentration of...

The objective of this work is to obtain a stable and natural antimicrobial delivery system. Thus, the effect of the addition of a natural polysaccharide such as welan gum on the linear viscoelastic properties, flow behaviour, droplet size distribution and physical stability of thyme oil/W emulsions formulated with a wheat-derived surfactant was...

BACKGROUND: Nanoemulsions formulated with citric essential oils are currently of interest because of their physical and chemical properties and multiple applications in areas such as the food industry or agrochemicals. These are thermodynamically unstable and have almost Newtonian flow behaviour, but a suitable formulation allows systems to be...

Este estudio se centra en el comportamiento interfacial del tensioactivo Appyclean 6548 en la interfase aceite de romero/agua. Se ha estudiado la tensión interfacial transitoria (γ) y la cinética de adsorción en función de la concentración de tensioactivo. Las curvas de tensión interfacial indican que a 0.5m/m% se alcanza la concentración de...

Background: New consumer habits are forcing the food industry to develop new and healthy products. In response to this tendency, in this investigation, we obtained nanoemulgels by microfluidization containing inulin fibre and omega-3 fatty acids. First, the influence of the number of microfluidization cycles on the physical properties of the...

El objetivo de este trabajo ha consistido en investigar cómo influye la presión aplicada en homogeneizador de alta presión con tecnología Microfluidizer® (2500, 5000, 7500, 10000, 12500 y 15000 psi) sobre la distribución de tamaños de gota y estabilidad física de una emulsión O/W formulada con aceite esencial de tomillo y un alquil...

Emulsions can be used as delivery systems for bioactive ingredients for their incorporation in food products. Essential oils are natural compounds found in plants that present antioxidant and antimicrobial activity. Therefore, the main goal of this work was to develop emulsions, containing mandarin essential oil stabilized by two food-grade...

El objetivo de esta investigación fue comparar tres tensoactivos ecológicos derivados del aceite de coco para la preparación de emulsiones aceite-en-agua concentradas formuladas con α-pineno. Los tensoactivos utilizados son ésteres polietoxilados de glicerina que presentan diferente número de grupos de óxido de etileno, que son responsables...
