Abstract

In order to improve the physical properties on moisture sorption of spray dried red ginseng extract powder (SD-RGEP), the various additives and coating agents were treated, and solubility, sedimentation rate and storage stability of RGEPs treated were investigated. For the moisture-proofing, additive itself was effective in the order casein>dextrin>starch>avicell, but RGEPs treated with additives were effective in the order cord oil+tween-40>starch>casein. But there was no significant difference between RGEP treated less than 1% additive and the moisture-proofing. The coating effect of AEA and CAP on RGEP could not be recognized for the moisture-proofing, whereas that of HPC, corn oil, lecithin and HPC+corn oil was proved to be very effective for the moisture-proofing of RGEP. Also it is required to control the initial moisture content of RGEP. The sedimentation rate of RGEP nontreated was 65.1 seconds, whereas that of RGEPs coated with 1% HPC, 1% corn oil, 1% lecithin and 1% HPC+0.5% corn oil was in the range of 96.2 to 114.3 seconds. The sedimentation rate of RGEPs coated was 1.5 to 1.8 times higher than that of RGEP nontreated, and there was significant difference between solubility and sedimentation rate. Therefore it was no matter for the keeping quality. The sorption rates of RGEPs coated with lecithin $(0.5{\sim}1.0%$), corn oil(0.8%) and cellulose acetate (0.8%) were ranged 54 to 56%, 51 to 55% and 52 to 54%, respectively, and it is found that the moisture-proofing effect of RGEPs coated was about 2 times higher than that of RGEP nontreated. From the result of storage experiment during 3 months under the maltreated condition of $48{\pm}2^{\circ}C$, 75% RH, the moisture sorption of RGEPs coated with corn oil$(0.5{\sim}1.0%$), cellulose acetate(DES, $0.5{\sim}0.8%$) and lecithin (DES, 1.0%) was not at all observed. Therefore it is considered that the circulating period of RGEPs coated with these coating agents could to give more than 3 years.
