Effect of Controlled Atmosphere and Modified Atmosphere Storage on the Fatty Acid of Fresh and Red Ginseng

수삼의 CA 및 MA 저장이 홍삼의 지방산에 미치는 영향

Fifteen free fatty acids including myristic acid were isolated and identified from red ginseng processed from CA and MA stored fresh ginseng. Linoleic acid (80%) and palmitic acid (10.5%) content were the major components accounting for more than 90% of the total free fatty acid. The contents of free and identified fatty acids were not greatly changed in all the treatments. Especially when preservative was treated, the change of free fatty acid was quite stable over the control. Each fraction of neutral, glyco- and phospholipid was constant in terms of quantities before and after the treatment.
