연근의 생리활성을 구명하기 위하여, in vitro에서 HMG-CoA reductase 저해능과 in vivo 에서 고콜레스테롤식이로 유발된 흰쥐의 고콜레스테롤혈증 개선효능을 실험하여 검토하였다. In vitro 에서 연근 에탄올 추출물은 HMG-CoA reductase 활성을 농도 의존적으로 저해하였다. In vivo 에서 고콜레스테롤 식이로 유발된 고콜레스테롤혈증 예방효과는 고콜레스테롤식이만을 급여한 HC군은 정상식이만을 급여한 NC군에 비하
Minimally processed lotus root was stored at 4 followed by dipping in distilled water, 3% ascorbic acid, 1% citric acid, 1% acetic acid, 1% EDTA, 2% lactic acid and 3% malic acid. The weight loss, color, soluble solids, pH, vitamin C and sensory characteristic were measured during storage period. The rate of weight loss decreased in the minimally processed lotus root. ΔL was changed slightly after 1 week storage and 1% acetic acid and 1% EDTA especially retarded a little retardation in browning during storage. Soluble solids was changed slightly, but decreased after 2 week storage in lotus root treated with 2% lactic acid and 3% malic acid. pH increased but vitamin C decreased during storage. The organoleptic quality of lotus root treated 1% EDTA showed the best by sensory evaluation.
