Studies on the Production and Optimal Drying Condition of Curcuma longa L.

Abstract

-We investigated the optimal cultivation system and dry processing method of rhizomes from Curcuma longa L.in Suncheon, the southern area of Korea. The experimental results are summarized as followings. Curcma longa rhizomes were transplanted on Apr. 30th, May 10th, and May 20th. The plant height, stem diameter, number of leaves and yield were highest in transplanted on May 10th. The fresh rhizome weight of Curcma longa was the heaviest in November 20 and the optimal dry temperature was 40℃. In sensory evaluations, there were significant differences among the Curcuma longa pills in terms of flavor, color, color and texture and overall acceptability, and honey added groups received significantly higher scores than the other groups.
