Book Description :

Abstract: Nanoemulsions are of great interest in food industry finding various food applications. However, oil‐in‐water (o/w) nanoemulsions have been intensively investigated, but there are few studies on w/o nanoemulsions. In the present work the preparation of nanoemulsions with olive oil using non‐ionic surfactants (Tween 20, 40, 60, 80, Span 20, 80) without the addition of a co‐surfactant was studied and their emulsion properties and stability were examined. The stable nanoemulsions were presented in ternary phase diagrams (oil–water‐surfactant) for each surfactant and the emulsifying ability of the efficient surfactants was determined. The nanoemulsions properties were evaluated in relationship to compositional components. From the results of this study it can be concluded that stable olive oil nanoemulsions without use of a co‐surfactant were obtained and moreover the most efficient type of emulsifier and its ratio of addition in the system were determined.

Book Description :

Abstract: Açaí berry is the fruit of an Amazonian palm tree and rich in anthocyanins (ACNs). Scientific studies have proven the health benefits of açaí berry and declared this fruit as "super fruit". ACNs have high antioxidant activities, but they are unstable and can easily deteriorate during food processing. In order to protect ACNs and increase their applicability, food-grade water-in-oil (W/O) emulsions were successfully formulated with different concentrations of açaí berry extracts (AEs). The formulated W/O nanoemulsions were relatively stable, with no phase separation after 30days of storage. The average droplet size varied between 146.8 and 814.8nm, with higher values corresponding to samples without AEs. All W/O nanoemulsion samples exhibited antioxidant activity and high retention rates of polyphenols after 30days of storage. ACN retention followed first-order kinetics, with high protection of ACNs observed in emulsified samples. 2% AE encapsulated in a 30wt% W/O nanoemulsion had an estimated half-life of 385days. The results indicate that stable nanoemulsion systems with high ACN protection can be produced with possible applications in the food and pharmaceutical industries. Graphical abstract: Highlights: Successful formulation of anthocyanin loaded water in oil nanoemulsions. Probable surfactant properties of açaí extracts Smaller droplet size distribution for samples emulsified with açaí extracts. Water-in-oil nanoemulsions have good antioxidant activity after 30days of storage. Degradation rate of anthocyanins decreased significant after encapsulation.

Book Description :

The objective of this research work was to formulate and develop an intranasal oil-in-water nanoemulsion (NE) using spontaneous emulsification method. Based on ternary phase diagram, emulsification time, and drug solubility study, the composition ratio of surfactant:co-surfactant:oil was optimized to 2:1:1. The model antiepileptic drug chosen for loading was phenytoin. The NE preparation was evaluated for particle size, zeta potential, electrical conductivity, pH, % transmittance, polarized light microscopy, in vitro drug release studies using HPLC, sterility validation, differential scanning calorimetry (DSC), and in vitro nasal toxicity testing in bovine nasal mucosa. The nanoemulsion formulations were then subjected to stability studies for six months by storing formulations at 25±5°C and 5±3°C. The NE exhibited a clear and stable formulation with globule size less than 20 nm and neutral zeta potential. The absence of birefringence and high conductivity values indicated that the formulations were o/w NE. The pH measurements confirmed compatibility of such formulation for intranasal delivery. In vitro release study showed 100% release of the drug from NE over a period of 48 hours. The absence of any endothermic events in the phenytoin - self nanoemulsifying mixture (SNE) when analyzed in DSC conclusively indicated that phenytoin was completely solubilized in this mixture.The histopathological studies of optimized formulation did not show signs of damage on the nasal mucosa.The results of the sterility verification test demonstrated that the sterilization of the final formulation using aseptic filtration with 0.22μm filter was sufficient for rendering the formulation aseptic. The nanoemulsion was found to be stable in all the temperature conditions when particle size distribution, drug content, pH, and conductivity were taken as stability indicating parameters during the six-month study period. Based on the obtained results, the o/w phenytoin NE was found to be stable and desirable for use in intra-nasal delivery.

Book Description :

This SpringerBrief provides an overview of ultrasonic emulsification and an update on recent advances in developing stable emulsions for the creation of novel drugs and functional foods, with a focus on bioactive delivery in these products. Emulsification is the process of combining two or more immiscible liquids to form a semi-stable mixture. These two liquids generally consist of an organic (oil) phase and an aqueous (water) phase that is stabilized by the addition of an emulsifier. Most common emulsions are of the oil-in-water (O/W) type, but can also be of water-in-oil (W/O) or even multiple emulsion types (i.e. double emulsions) in the form of water-in-oil-in-water (W/O/W) or oil-in-water-in-oil (O/W/O) phases. The formation of an emulsion requires input of energy to distribute the disperse phase in the continuous phase in small-sized droplets that are able to resist instability. There is great interest in the use of ultrasound to produce emulsions, as it is able to do so relatively efficiently and effectively compared to existing techniques such as rotor stator, high-pressure homogenization and microfluidization. The interaction of ultrasound with the hydrocolloids and biopolymers that are often used to stabilize emulsions can offer advantages such as improved stability or greater control of formed droplet size distributions.
