The objective of this study was to evaluate the mechanical quality of cultivars that could potentially be used to processed cooked rice. Proximate composition, amylose content, cooking quality, and the Toyo value, were higher in Jungsaenggold than in the other cultivars. The results showed that the crude protein contents of the rice cultivars were between 4.60 and 6.59%. The amylose content was the highest in the Haedam cultivar (21.36%), but was the lowest in the Jungsaenggold cultivar (17.11%). Cooking quality was the highest in the Haiami and Jungsaenggold cultivar. Texture analyzer test showed that Ilpum had the lowest hardness and highest stickiness. Significant differences in the palatability characteristics (Toyo results for glossiness quality) of the rice flour were recorded using a Toyo Meter Analyzer. Ilpum, Samkwang, Haiami and Jungsaenggold had low amylose contents and the highest Toyo values. Thus, the results of this study suggested that Jungsaenggold can be effectively used to produce processed cooked rice.

어린잎 채소는 조직이 연하고 부드러워 가공, 포장, 유통시에 물리적인 상해를 받기 쉬우며 수확 후 수분증발 및 성분 변화 등으로 품질이 급격히 저하된다. 본 연구는 어린잎 채소 중에서 다채의 수확 후 생리특성을 구명하고 적정 포장방법을 개발하고자 수행하였다. 공시재료는 연구소 온실에서 2007년 1월 29일에 다채 종자를 플러그 트레이에 파종하여 30일 정도 키운 다채를 사용하였으며, 수확 후 에서 12시간 예냉 처리한 후 P-plus 필름,

Typhoon "MAEMI", happened in September 2003, hit the great damage to Gyeongnam province area. Especially, rice plant was lodged or severe leaf damage was caused. This study was conducted to find out the extents of leaf damage among different rice cultivars, and to evaluate rice yield and eating quality due to leaf damage after typhoon. Rice cultivars torn off over half of the flag leaf length (FLL) were one medium-late maturing cultivar (Donginl), medium maturing cultivar (Yeonganbyeo), eight early maturing cultivars (Samcheonbyeo, Jounghwnbyeo, Munjangbyeo, Taebongbyeo, Odaebyeo, Samhaegbyeo, Sobaegbyeo, Sinunbongbyeo), two long-il type cultivars (Samgangbyeo, Namcheonbyeo), and three special use cultivars (Heukseonchalbyeo, Jinbuchalbyeo, Yangjobyeo). Cultivars torn off below 1/10 FLL were eight medium-late maturing cultivars (Chucheongbyeo, Daecheongbyeo, Saechu cheongbyeo, Donganbyeo, Daeyabyeo, Hwamyeongbyeo, 방eongsanbyeo, Dongjinbyeo) and two medium maturing cultivays (Donghaebyeo, Gumobyeo2). The rest cultivars were tore off by 1/10∼1/2 ELL. In yield components, the longer was flag leaf damage, the lower was ripened grain ratio, grain weight and brown/rough rice ratio, which was severly impacted to late than to ordinary season cultivation. However, rice yield did not decrease up to tearing by 1/10 ELL. Head rice ratio decreased from flag leaf tearing over 1/10 ELL in late season cultivation. The longer was flag leaf damage, the lower was eating quality, which could not show significantly different.

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 10~30분이 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.
