Abstract:
Propolis is a resin compound which is collected from different Plant sources by bees. It is processed by salivary enzymes and is combined with wax bee and is used in hives, Specially in entrance door. In this study Propolis is selected as a natural substance. The aim of this study is to change the substance to get use of in industry. For this, first, antimicrobial properties of it was proved and then for industrial use encapsulation was done to keep the capability of it. Since propolis extract was prepared with 70% ethanol, and the encapsulation was done with the polymer-effective material ratio of 5,0,1,2 by a proper polymer with no bad effect on the body. Later an appropriate powder was produced In terms of appearance. After checking antibacterial properties of samples and providing absorbance profiles and Acceleration test, best samples with the polymer-effective material ratio of 2 was selected. Potency of the best sample was calculated which was 66% than original extract
