| 1) Alcohol extraction method |
An amount of ethanol is inserted into the raw material of propolis prior to entering the fermentation stage. Propolis contains
a lot of fat-soluble materials, which easily melt in alcohol, thereby allowing greatest amounts of extraction. Products that have
been created through the alcohol extraction method have a very high purity, which makes them highly effective. |
|
| 2) Water extraction method |
Water is inserted into the raw material of propolis for extraction. This method of extraction holds a great advantage in that it has
a smoother taste and smell than products that have been extracted with alcohol. However, propolis is composed mostly of oil ingredients, which makes it difficult for them to melt in water, thereby preventing effective extraction. |
|
| 3) Micellization extraction method (emulsification extraction method) |
| The method involves the addition of chemical additives that have been extracted into alcohol to propolis. The use of this method makes the taste of the propolis more smooth since chemical additives are included. |
|
| 4) Super critical extraction method |
| The method involves the addition of chemical additives that have been extracted into alcohol to propolis. The use of this method makes the taste of the propolis more smooth since chemical additives are included. |
