what is difference between nano-emulsion and nano-encapsulation? are these 2 completely different nanoformulation technique? how we can compare these?
Nano emulsions are biphasic liquid preparations with nano sizes droplets of one liquid solution of drug dispersed in a continuous medium. Nano encapsulation is a broad general term which may apply to all the nano solid and liquid preparations where core material is encapsulated in a coat or polymeric material with different techniques..
Dear Arezoo,
Nano-encapsulation offers great advantage for an improved stability of bioactive compounds in certain food formulations. Jelly as a staple food is considered to be a useful model to develop new generation of functional products, and to test the stability of nano-encapsulated bioactive compounds. In this study, bioactive compounds were encapsulated with dextran and added to jelly formulation to test their stability during the process. The results revealed that nano-encapsulation significantly improved the thermal stability of eugenol at elevated temperatures applied during process. Addition of the particles of encapsulated bioactive compounds at amounts up to 0.02 % in jelly formulation seemed reasonable in terms of general quality parameters and sensory properties. Presence of bioactive compounds in a formulation may bring important changes in the chemical reactions occurring in food during processing. The most bioactive compounds bear functional groups that may react with other compounds in food. These reactions may lead to the formation of processing contaminants especially in products in which processing conditions are severe. Therefore, prevention of the reactivity of bioactive compounds through their nano-encapsulation may also help preventing certain food safety risks

Yes !! JS Patil have already been answered, nanoemulsion is biphasic liquid system in which nanoglobules as dispersed phase in the dispersion medium. In addition, organic solvent is considered as oil phase in the development of nanoemulsion or microemulsion.
