The objective of this work is to develop a novel coacervation process to produce microcapsules of polylactide (PLA) to encapsulate thyme oil that will be used in cosmetics. The novelty of this approach consists of dissolving PLA in dimethylformamide (DMF) which is a good solvent for PLA but in addition has high solubility in water. Upon contact with water, the homogeneous solution of PLA in DMF...
The microencapsulation of tuna oil in gelatin-sodium hexametaphosphate (SHMP) using complex coacervation was optimised for the stabilisation of omega-3 oils, for use as a functional food ingredient. Firstly, oil stability was optimised by comparing the accelerated stability of tuna oil in the presence of various commercial antioxidants, using a Rancimat™. Then zeta-potential (mV), turbidity and...
The method for preparation of vesicles, by evaporation of hydrophobic solvent from double emulsion (w/o/w) formed in the properly designed device is described. These method leads to multiple increase of encapsulation efficiency of aqueous solutions of drug in liposomes in comparison with other method. The w/o/w was passed through the glass sinter with the use of negative pressure to disrupt w/o...
A novel, bio-inspired templating platform technology is reported for the synthesis of biocompatible oil-core silica-shell nanocapsules with tunable shell thickness by utilizing a designed bifunctional peptide. Furthermore, facile encapsulation of an active molecule and its sustained release are demonstrated.
background: thymus daenensis is on e of the endemic aromatic species in iran that its essential oil is used in food and pharmaceutical industries. objective: in this study, the effects of plant growth stages and distillation methods on essential oil content and thymol percentage of this species were evaluated. methods: the aerial parts of th. daenensis were collected in three stages of plant gr...
Bioactive essential oil components, aldehydes, terpenes and phenols can be encapsulated into nanosized emulsified droplets. Nano-encapsulated bioactive oils emulsions were prepared by high amplitude ultrasonic homogenization with food grade ingredients. The effect of delivery system on the antimicrobial activity of different oils components, e.g., carvacrol, lemon grass and cinnamaldehyde, was ...
BACKGROUND Essential oil components (EOCs) are known for their antifungal properties; however, their high volatility limits their application as antimicrobial agents. Strategies used for controlling the volatility of EOCs include encapsulation or loading into porous materials. This study evaluated the in vitro antifungal activity of selected EOCs (carvacrol, cinnamaldehyde, eugenol and thymol) ...
in order to study the response of concentration and composition of essential oil of coriander (coriandrum sativum) to cattle manure and nitrogen fixing bacteria, an experiment was conducted as factorial experiment in the base of randomized complete blocks design with twelve treatments and three replications at homand research station in damavand of iran in 2010. the factors were cattle manure i...
