다양한 침지 저장액에 의한 깐밤의 갈변억제에 따른 저장 효과를 비교하였다. 총 폴리페놀의 함량은 저장초기에 13.36 mg%로 매우 낮게 나타났으나, 무처리구는 저장 17일까지 59.12 mg%로 증가 후 다시 감소하였다. 전해산화수 처리구는 저장 8일에 61.02 mg%로 갑작스런 증가를 보인 후 감소하였고, 그 외의 처리구에서는 저장 초기에 미세한 변화를 보이다가 저장 11일에 갑작 스럽게 증가하는 경량을 나타내었다. Polyphenol ox

Ginseng was stored at a temperature lower than the freezing point after a treatment of freezing point depressing agents to extend its freshness. Respiration rate at freezing point of ginseng, -1.70.1, was inhibited 92% and 97% compared with those stored at 5or 20 , respectively. Sorbitol solution chosen as a freezing point depressing agent lowered the freezing point of ginseng to about -3.0. Ginsengs treated with the sorbitol solution and packaged with 0.06mm LDPE was stored at -2 , and the quality change was then compared with ginsengs stored at 0 and 5. Weight loss of ginsengs stored at -2 for 100days was 1.5%, which is about 2.6times less than those stored at 5. However, there were no significant difference between the ginsengs stored at -2 and at 0(1.9%). Spoilage rate of the ginsengs was 100% after 50 days of storage at 5 and 25% after 100days at 0respectively. but that of ginsengs stored at -2 was 13%, which was half than that of ginsengs stored at 0. Firmness and amount of monoscaccharides in ginsengs were decreased during storage at 5 or 0 but ginsengs stored at -2 showed better firmness and an increase in monosaccharides such as fructose and glucose. From above, when ginseng treated with freezing pont depressing agents were stored at -2, the shelf life was extended to 2 or 3 times longer than those that were stored at 5 or 0, respectively.
