Extensive documentation on the antimicrobial properties of essential oils and their constituents has been carried out by several workers. Although the mechanism of action of a few essential oil components has been elucidated in many pioneering works in the past, detailed knowledge of most of the compounds and their mechanism of action is still lacking. This knowledge is particularly important f...

A collaboration between WPI and ENSIC was undertaken to investigate the properties of emulsions as a drug delivery system. The use of biocompatible amphiphilic polymers as emulsifiers for controlled drug delivery is a relatively new technology. The emulsifier acts as a barrier between phases in oil-in-water emulsions to increase stability. Oil soluble drug substances can then be encapsulated wi...

*Correspo Engineer USA. E-mail: v We evaluate the feasibility of electrospinning oil-in-water type emulsions. The emulsions had an aqueous solution of polyethylene oxide (PEO) as the continuous phase, and either mineral oil or a polystyrene (PS) in toluene solution as the drop phase. The Taylor cones and electrified liquid jets were stable even when the emulsion drops were as large as a few-ten...

The aim of this study was to develop a stable hydrogel carrier system for thyme essential oil (TEO) that could protect its sensitive polyphenol compounds. impact wall material (soy protein and alginate) on encapsulation efficiency thymol release in simulated gastrointestinal conditions, investigated. ~ 80 % 20 gastric pancreatic solutions, respectively. Thyme plays an important role as antimicr...

In this study, cinnamon essential oil (CEO) nanocapsules were stabilized by means of bacterial cellulose nanocrystals (BCNCs) and encapsulated using fish gelatin as the main polymer phase. Emulsions prepared at pH 5 different CEO concentrations (0.03, 0.06, 0.12, 0.24, 0.36, 0.48% v/w) a fixed amount (3% w/w) BCNCs (0.06% w/w). The controlled release was assessed studies, which revealed that hi...

The anti-yeast activity of oil-in-water encapsulated nanoemulsion containing individual or a combination the three essential oils Tasmanian pepper leaf (Tasmannia lanceolata), lemon myrtle (Backhousia citriodora), and anise (Syzygium anisatum) against weak-acid resistant Zygosaccharomyces bailii in clear apple juice was investigated. effectiveness shelf-life extension Z. bailii-spiked (1 × 103 ...

a study was conducted to investigate the effect of different planting densities and nitrogen doses on essential oil content and yield in herb and leaves of basil (ocimum basilicum l.). the research was conducted during 2007 and 2008 using split-plot randomized complete block design with four replications. the experiment consisted of four plant densities (30×20, 40×20 and 50×20 cm) as the main p...

Cinnamon essential oil (CEO) was successfully encapsulated into chitosan (CS) nanoparticles at different loading amounts (1%, 1.5%, 2%, and 2.5% v/v) using oil-in-water (o/w) emulsion and ionic-gelation methods. In order to form active packaging, poly(lactic acid) (PLA) was used to fabricate PLA/CS-CEO composite fibers using a simple electrospinning method. The shape, size, zeta potential, and ...
