Abstract

This experiment was carried out to determine the adequate machine peeling and retting time of peony roots, which are used as medicinal resources in Korea. When the roots were peeled for $10{\sim}30$ minitues in the peeling machine, the epidermis of root was removed, and higher yield was obtained and paeoniflorin content as compared with roots which were peeled for longer time. The paeoniflorin content of root varied with the different parts of root. The highest content was recorded in the upper part and the lowest in the middle part. The loss of paeoniflorin increased in the roots processed for expanded peeling and retting time. Lightness of peeled root was higher and ${\Delta}\;E$ was lower in the roots which were peeled by machine for longer time.

작약 수확후 건조과정중 양질의 약재 생산을 위한 기초자료를 얻고자 뿌리약초 박피기를 이용하여 껍질제거시 박피시간을 달리하여 시험한 결과를 요약하면 다음과 같다. 작약근의 기계박피시 표피 부분만 제거하고 피층부분의 수량손실과 paeoniflirin 함량의 손실을 방지하기 위한 적정 기계박피시간은 1회에 $10{\sim}30$분이 었다. 작약근 부위별 paeoniflorin 함량은 박피시간이 길어질수록 감소하였고, 상위부>하위부>중위부 순으로 노두부분과 인접한 상위부가 가장 높았다. 건조 작약 절단 전에 수처리시 박피 및 수침시간이 길어질수록 paeoniflorin의 유실량이 많았고, 색도 변화는 박피시간이 길어짐에 따라 적갈색의 표피 부분이 제거되어 명도가 증가하고 총 색도가 감소하였다.
