A determination of rational parameters for drying plant extracts of wild and cultivated plants with antioxidant properties

Abstract

The article focuses on the drying of callus extracts of Ocimum basilicum and Eleutherococcus senticosus by pseudo-boiling bed method. During the study, rational conditions for the drying process were determined: temperature 90 ℃, aspiration 100 ± 0.8 m3/h and solution feed rate of 8 ± 0.3ml/min. It was possible to increase the antioxidant activity of the extract under the given conditions. The study of fluidized bed drying of the extract of callus cultures of basil (Ocimum basilicum) and Eleutherococcus senticosus (Eleutherococcus senticosus) allows to obtain extracts with higher concentration of biologically active substances. The results of the article can be useful for agro-, bio- and food industries. © The Authors, published by EDP Sciences.
