“…In addition to common microencapsulation techniques explained above, there are limited oil encapsulation studies including single layer emulsions [164,165]; multilayer emulsions [166,167]; molecular inclusion [168][169][170]; use of particles from gassaturated solution (PGSS) process [171]; use of macroscopic beads [172] and miniemulsification-solvent evaporation technique [173]. In particular, new and expensive methods are evaluated to preserve volatile compounds of essential oils.…”

Heat, oxygen, moisture and light are the main causes of oxidation reactions in lipid containing foods. In particular, lipid oxidation is a major problem for unsaturated lipids. Until recent years, natural or synthetic antioxidants have been widely used in oils to retard oxidative deteriorations. Nowadays, encapsulation of oils like other sensitive materials such as vitamins, colorants, phenolic compounds or probiotic bacteria by various techniques have become increasingly popular as a promising preservation method. On the other hand, encapsulation improves handling properties of oils as well as protecting oils against oxidation. Spray drying is the most preferred encapsulation technique due to its lower operating costs and simplicity. Freeze-drying, coacervation and emulsification are the other well-known encapsulation methods. However, process parameters of these methods have extremely important effect on storage stability of encapsulated oils. As for encapsulated oils by drying, also the characteristics of powder products are greatly influenced by process variables. Many studies have been carried out to optimize process factors for encapsulation of oils with a maximum efficiency. In this review, common practices used for oil encapsulation and the oxidative stability of encapsulated oils are discussed in detail. Furthermore, effects of environmental conditions on storage stability of encapsulated oils during storage are also reviewed.

“…Many studies on the physical and chemical methods to control release in such a system have been conducted. Changes in temperature [14], pressure, and ultrasonic intensity [15] can control the release of molecules from the CD complex. The studies [16,17] published thus far suggested that modification of CD was very valuable in changing the rate of drug release.…”

A novel cyclodextrin (CD)-based controlled release system was developed in the small intestine to control the rate of drug release, on the premise of enteric-coated tablets. The system was designed based on the enzymes exogenous β-cyclodextrin glycosyltransferase (β-CGTase) and endogenous maltase-glucoamylase (MG), wherein MG is secreted in the small intestine and substituted by a congenerous amyloglucosidase (AG). The vanillin-/curcumin-β-CD complexes were prepared and detected by Fourier transform infrared (FT-IR), thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC), and host CD degradation was measured based on the glucose yield. The combination of β-CGTase and AG was also functional in the CD complex system. The variations in the concentrations of added β-CGTase, with AG constantly in excess, could effectively alter the rate of host CD degradation and guest release by monitoring glucose production and color disappearance, thus, demonstrating that guest release in the CD complex system could be precisely controlled by changing the amount of β-CGTase used. Thus, the in vitro simulation of the system indicated that a novel controlled release system, based on endogenous MG, could be established in the small intestine. The CD-based controlled release system can be potentially applied in drug delivery and absorption in the small intestine.

“…Then the resulting slurry was dried in the air dry oven for 48 h.Finally,it was pulverized after dried. Morphology of microencapsulation [6].The shape and surface characteristics of the microencapsules were examined using a scanning electron microscope at required magnifications with the secondary electron image (SEI) as a detector and an accelerated voltage of 14 kV.Put the conductive adhesive in SEM sample table and the microencapsule powder was spread on the double-sided adhesive. Then sprayed gold with vacuum-pumping.The microencapsules were magnified 500 and 200 times.…”

In this paper,the clove essential oil was combined with β-Cyclodextrin and chitosan using the method of envelope binding,thus clove essential oil microencapsule antistaling agent was prepared.To detect the exterior characterization of microcapsule using SEM;To analyze the antimicrobial properties of microencapsules using the inhibition zone method, and the slow release rate of microencapsule was detected in 0, 2,30 °C. The results showed that the microencapsule had irregular shapes and their surfaces were covered with many cracks;the inhibition zone diameter of Rhizopus sp. and Penicillium citrinum diameter were 1.2 cm and 1.6 cm partly; microencapsules showed a slow release state under the three temperature conditions,and it had the slowest release rate under 0 °C condition.
