병결점 부근의 저장온도에 따른 수삼의 내적 품질 변화 연구로 수삼을 각각 , 및 에서 16주간 저장하면서 저장온도에 따른 호흡률, 경도, 가용성 고형물함량, 전분함량, pH, 사포닌함량과 관능적 품질의 변화를 조사하였다. 수삼의 호흡률은 저장온도가 낮을수록 낮았으나 그 차이는 미미하였다. 수삼 표피층의 정도는 저장기간이 경과됨에 따라 증가하였고, 내부 조직의 경도는 감소하는 경향을 보였으나 저장온도에 따라 경도 변화의 차이는 뚜렷하지 않았다.
As a serial study to investigate optimum storing temperature of fresh ginseng (Panax ginseng C. A. Meyer), the respiration rate and internal quality of the ginseng was compared during storage for 16 weeks at , and . At initial storage period, respiration rate of fresh ginseng was lower at lower temperature, but thereafter it was negligible. Changes in the firmness of fresh ginseng were not significantly different by the storage temperature. The soluble solids content in fresh ginseng was rapidly increased in the early part of storage, and fresh ginseng stored at a lower temperature had a lower content of soluble solids. The iodine-stained color for starch of the main root was rapidly changed for 4 weeks, and L value of the color was the highest in the center, followed by the cambium and the cortex. pH were a little change depending upon the storage temperature, and as a whole, pH was the lowest at , followed by and . Although the content of crude saponin tended to somewhat increased as the storage period passed, the effect of storage temperature on changes in the content was not clear. In the sensory evaluation of 'unique flavor' of fresh ginseng using 5 point scale, higher than 3 point was marked for 8 weeks at , 14 weeks at and 16 weeks at during storage (p < 0.05).
