POTENTIALITY OF NEEM (AZADIRACHTA INDICA) POWDER IN RHEOLOGY MODIFICATION OF OIL-IN-WATER EMULSION

摘要

Rheology modification of the complex fluids has been addressed using the competencyrnof the selected natural materials. This article reports the efficacy of thernmicroparticles of the naturally available material neem (Azadirachta indica)rnpowder as rheology modifier, which in turn offers better consistency, firmness, asrnwell as nutrient value to the emulsions containing juice of Aloe barbadenisrnMiller, which can be effectively used for the preparation of foods, pharmaceuticalsrnand personal care products. These results showed that the oil–water emulsionsrncontaining aloe vera juice emulsified with coconut milk protein exhibitedrnuseful dynamic viscoelastic behavior, with improved consistency and rheologyrnbecause of the addition of microparticles of neem. Neem microparticles offeredrnhigher yield stress and apparent viscosity. This rheology modifier materialrncan potentially eliminate or reduce the use of synthetic chemical thickeners,rntexturizers, etc.
