Evaluation of physicochemical properties of violet tree (Securida longepedunculata) root powder

Abstract

The evaluation of physicochemical properties of modified and unmodified Violet Tree Root Powder (UVTRP/MVTRP) were examined on, ash content, moisture content, volatile content, fixed carbon, and bulk density. Others include porosity, specific gravity, swelling ability and anti-swelling efficiency. The values for unmodified and modified VTRP biomass compared, were ash content 9.60 ±0.03 % - 7.30 ±0.25 %, moisture content 17.14 ±1.24 % - 8.95 ±1.00 %, volatile content 32.70 ±0.20 % - 40.50 ±1.45 %, fixed carbon 57.70 ±3.26 % - 52.20 ±2.25 % and bulk density 23.30 ±0.28 g/cm3 – 27.85 ±0.01 g/cm3. The value for porosity was 67.80 ±0.01 % - 83.30 ±2.34%, specific gravity 0.6909 ±1.50 – 0.9906 ±1.25, swelling ability 86.70 ±1.36 % - 33.50 ±1.50 % accordingly, while the anti-swelling efficiency modified VTRP gave 61.36 ±2.44 %. The improved physicochemical values were indications of a better behavior of the modified VTRP for various application.
