Ultrafine Powderization Using Low Temperature Turbo Mill to Improve Water Solubility of Red Ginseng Powder

초록

Ultrafine powder of roasted red ginseng was produced, using a low temperature turbo mill, and then the particle size distribution, water solubility index and Rg3 content of coarse and ultrafine powder was investigated. The mean particle size of ultrafine powder is abruptly decreased from < 1250 mu m into about 30 mu m, and there is more than 20 times reduction in particle size, compared to that of control. The difference of particle size between d((0.1)) and d((0.9)) is about 50 mu m in ultrafine powder after milling. The water solubility index of ultrafine powder was about 17 % higher than that of control. Therefore, ultrafine powder can be applied in developing new capsule and tablet product.
