RODRIGUEZ RODRIGUEZ, Luis Enrique et al. Optimization of the alcoholic extraction to obtain concentrated solutions of propolis. Rev. colomb. cienc. quim. farm. [online]. 2015, vol.44, n.1, pp.47-57. ISSN 0034-7418.  https://doi.org/10.15446/rcciquifa.v44n1.54237.

Introduction: There are different methods to obtain concentrated propolis solution that have used by different national and international authors. In this document a variant of Pichansky method is proposed to optimize the process for obtaining concentrated propolis in the Immunology and Blood by Product Center. Objective: To optimize the process of obtaining concentrated propolis alcoholic solutions through a sequence of steps of extraction/filtration to remove dissolved contaminants and increase the quality of the final product. Materials and methods: To obtain solutions, three experimental plots were performed. This process was executed with three successive extractions using alcohol intermediate to temperature controlled. The quality parameters were determined according to procedures implemented of management system. A comparison was performed between experimental batches and batches subsequently produced with the change. The information was processed statistically by means of (means t-test) with Medcal software. Results: The optimal values of volume of total solids concentration above 30% were obtained for all tested batches of concentrated solutions, the organoleptic properties were found according to the standard quality. Conclusions: It was possible to optimize the process of obtaining the propolis concentrated solution of maintaining product compliance, achieving a better recovery of the first product due to considering the addition of a third step in the process with a controlled temperature.
