Studies on the Physicochemical Properties of Korean Ginseng (Panax ginseng, C.M. Meyer) Root Starch 1. Starch Cantent and General Feachures

This study was conducted to investigated the morphology and distribution of starch granule in ginseng root. The results obtained are as follows; The starch contents of main and lateral ginseng 1$.$cot were 23-32% and 14-16%, respectively, and it was varied significantly with growing season, namely 15-37% in Summer (May to August) and 3-6% in Winter (November to March). Thus the starch content of ginseng root was different depending on the portien of ginseng root and growing seasons, but a significant difference was not observed by a growing period of ginseng. The starch granules showed nearly round or oval shape having the diameter 2-8${\mu}$ and their size were increased with a growing period of ginseng. The crystalline structure of starch granules was found to be B-type by X-ray diffraction study.
