The study was concerned with the dehydration kinetics of aroids in mechanical dryer at different dryingcondition such as variable air dry bulb temperature and air velocity. Fresh aroids with 3, 5 mm slice and 8mm cube were used as raw materials for drying. The experimental results showed that drying rate constantand thickness can be expressed as power law equation. The exponent of the equation for aroids was 1.15indicating presence of significance external mass transfer resistance. Increasing loading density gavedecreased drying rate constant and when air velocity of dryer was increased, drying rate constant was alsoincreased, as higher air velocity reduces the external resistance to mass transfer and also highertemperature gave faster drying rate. The activation energy of diffusion of water from aroids during dryingas per Arrhenius equation was found to be 5.12 k cal/g-mole. The chemical compositions of fresh and driedaroids were determined and it was observed that all the constituent remained almost constant, only fatdecreased slightly possibly due to oxidation. Organoleptic taste testing showed that “chapatti” preparedfrom aroids powder (aroids powder: wheat flour = 1:4) were adjudged to be the best by the panelists using1-9 hedonic scale and ranked as like moderately securing score 7.3.Journal of Chemical Engineering Vol.ChE 24 2006 19-24

Konjac glucomannan (KGM) has been widely used in pharmaceutical, chemical engineering, food industry, drug carrier delivery, etc. The sol-gel transition kinetics of KGM dilute solution was studied by steady fluorescence spectroscopy in this article. The results showed that the gel point of KGM solutions depend on the concentration of KGM, pH value and temperature. The sol-gel phase transition activation energy, ΔE, was calculated to be 83.1 kJ/mol based on first reaction kinetic model.
