Abstract

Aloe vera powder was made from aloe vera clear gel (mucilage) which was dried with an oven blower at 70"C until a moisture content of between 8.0-10.00/o was reached.The previous research showed that aloe verapowder had high antioxidative activity. However, the use of aloe vera powder are less acceptable, because of low solubility and was needed special preparation to drink. The purposes of this research was to improve aloe aera powder solubilityby microencapsulation, thus increasing the acceptability.The microencapsulation was conducted by reconstituting aloe -oera powder in aqueous medium with ratio of powder/water 7/!20. The mixture was filtered and then the solution added with maltodextrin as an encapsulating agent with various concentration of, 2.5; 5.0;7 .5 and 70.0 o/o(w/v). Each preparation was fed into spray dryer at an iniet temperature of 130"C and an outlet temperature of 103"C with the air flow rate was 50.0 m3lh and the solution flow rate 350.0 mllh. fhe microencapsulated powders were determined their acceptability by hedonic test and were tested the colour with chromameter. The antioxidative activity of the acceptable microencapsulated-powder was analyzed by using DPPH (l,t-Diphenyl-2-picrylhydrazifl method. The experiment used completely randomized design with maltodextrin concentration as a factor. The research showed that microencapsulation of aloe vera powder with 7.50/o maltodextrin resulted acceptable product. The colour of the microencapsulated powder was light rather yellow and the ability to scavenge free radical DPPH indicated by the value of RS A (Radical Scar.tenging Actioity) was betwee n 78.70-L9 .720/o. Keywords: solubiliry maltodextrin, microencapsulated-powder.
