Propolis Extraction Using Vacuum Resistive Heating Method

Abstract

Indonesian raw propolis as herbal medicine is produced by many farms but the bioactive content is not yet known. An innovative propolis extractor based on vacuum ohmic heating emerged. Vacuum ohmic heating is an extraction technology that uses an electric current that is carried out in a vacuum. This study aims to determine the effect of the origin of propolis on chemical characteristics extract using propolis extractor machine and compared with commercial propolis. This study used completely randomized design method with the origin of propolis variations. The extraction process was carried out in two stages. The results were compared with commercial product. The highest total phenol and flavonoid in vacuum resistive heating method was obtained in Makassar propolis while the lowest was obtained from Bali. In conclusion, the origin of the propolis area affects the results of propolis extraction using vacuum resistive heating technology to the parameters of total phenol and total flavonoids. By knowing the difference in the yield of bioactive compounds in propolis, it can be seen which propolis is best for use in producing herbal medicine propolis as a source of antioxidants.
