Development of a technique for psyllium husk mucilage purification with simultaneous microencapsulation of curcumin

Abstract

This study focused on evaluating a technique for the psyllium husk mucilage (PHM) purification with simultaneous microencapsulation of curcumin. PHM was extracted with water and purified with ethanol. For the mucilage purification and simultaneous microencapsulation, an ethanolic solution of curcumin was used. After dehydration, the samples were analysed by instrumental techniques and evaluated for thermal stability. The presence of curcumin in the solution did not impair the yield of precipitated polysaccharide. Interactions of the dye and carbohydrates were confirmed by displacement of peaks in FT-IR and FT-Raman spectroscopy. The onset temperature of degradation of microcapsules was superior to that of curcumin. Thermal stability in solution at 90°C also improved. After 300 minutes of heating, the microcapsules had a remnant curcumin content exceeding 70%, while, in standard sample, the remaining curcumin content was 4.46%. Thus, the developed technique was successful on purification of PHM and microencapsulation of curcumin.

Enhanced bactericidal and in vivo wound healing potential of biosynthesized zinc oxide nanoparticles from psyllium mucilage

“…[24,25] PG is also widely used for constipation prevention, cholesterol reduction, intestinal regulation, film formation, wastewater treatment, and encapsulation of colourants (Figure S1). [26] The present research emphasized the green synthesis of PG-ZnO-NPs, which has not been reported. The PG-Zn-NPs are synthesized by evaporation and calcination and were characterized by various analytical techniques such as UV-Vis, FTIR, PL, and SEM-EDX.…”

Effective encapsulation of reuterin-producing Limosilactobacillus reuteri in alginate beads prepared with different mucilages/gums

“…The FT-IR spectrum of psyllium mucilage showed bands at 1726 cm −1 and 1649 cm −1 , whose are characteristics vibration of ester carbonyl group and carboxylic group [35] . The stretching vibration of C–O–C group was detected at 1049 cm −1 , suggesting the presence of arabinoxylans ( [35] ; Monge [42] ). In parallel, the konjac gum FT-IR spectra detected bands at 1730 and 1651 cm −1 with stretching vibrations that are characteristics assigned to acetyl groups (C=O) and the presence of amide groups (–CONH–), respectively [43] .…”

In Vitro/In Vivo Evaluation of Clomipramine Orodispersible Tablets for the Treatment of Depression and Obsessive-Compulsive Disorder

“…A rotary extractor was used to extract the ethanol from the precipitate. The spray drying technique was used for drying the samples [ 46 ]. After drying, the samples were stored in a well-closed container for further use.…”
