Nano encapsulation is a process in which tiny particles and droplets are surrounded by coating to give out small capsules that has useful properties. These small capsules often have diameters between micrometers to a few millimeters. This has been widely used in most foods. Each class of a certain food is encapsulated, mostly with flavors. The technique would often vary depending on the physical and chemical properties of the material.
There are several reasons why these methods has been further developed. Mostly, a specific core will be taken away and isolated from its environment same as isolating vitamins from the decaying effects that are caused by oxygen. Using such may further improve the handling property of a particular sticky substance. Pesticides also make use of such to minimize volatilization risks and leaching.
The walls must definitely be ruptured upon use even though its aim is just to isolate the core from the environment. This can be simply done by putting shear stress or pressure in it. Some enzyme attacks, solvent actions, chemical reactions and hydrolysis can even be considered in breaking it.
There are numerous techniques that could simplify the entire process. Currently, more and more techniques are constantly developed and innovated. A common technique would be pan coating. This is widely used in the world of pharmaceuticals. It is one of the oldest ways that is used to coat and make some tablets. All of the particles that will be needed are arranged in a particular pan or other device while a coating material will be applied slowly.
Another technique would be the centrifugal extrusion where all liquids will be encapsulated by using a certain rotating bump head. As it slowly rotates, a solvent might be released from the solution. Such process is applicable to particles that have smaller diameters. This is also limited for liquid substances as well.
This can also be used to release a certain drug slowly into the body. This can also decrease toxic side effects for various drugs by preventing high initial concentrations in the blood. There is often a desired pattern to release such. The more typical release pattern is first order where the rate decreases exponentially over time until the drug source is exhausted.
These processes offer different levels of complexity, capacity and operating cost with relative comparisons. These can all be applied in various areas such as pharmaceuticals, food and nutriceuticals, consumer and diversified products and some agricultural and industrial fields. This might also be used to embed a certain fragrance for some brands of perfume. It can also be used to further extend the shelf life and stability of various commodities such as vitamins.
A nanocapsule usually has several shapes and sizes. It could have many compositions as well. A certain encapsulated particle may take a uniform or regular appearance and it can also have an irregular and odd shape.
Nano encapsulation definitely made its way up to this time. Before, it was only considered a smaller process of microencapsulation. Still, it is similar to such particularly the techniques that are used in production. Because of technology, things has greatly improved and life became easier and simpler through the years.
