THE APPLICATION OF MULTISTAGE COUNTERCURRENT EXTRACTION AND SPRAY DRYING IN THE PRODUCTION OF INSTANT POWDER FROM GANODERMA LUCIDUM.

Abstract

This research focussed on the multistage countercurrent extraction and spray drying in the production of instant powder from Ganoderma lucidum. The five stage extraction was considered as an optimal process. In spray drying, the optimal concentration of dry matters of feed was 35%, inlet and outlet temperatures of drying agent -18012°C and 722°C respectively and pressure for rotary atomizer - 3,8 bar. The product recovery yield of the spray drying was 91,7%. The moisture of the instant powder of Ganoderma lucidum was 4,2%. The qualitative test showed that the obtained product contained saponine. The determined technological parameters were fundamental references for the application of the two processes above in industrial scale.
