초록
분포량이 많고 식용되고 있는 중요해조인 둥근돌김, 잎파래, 구멍갈파래, 미역, 톳, 모자반, 셀만모자반, 누운청각의 식염가용성 및 알콜가용성 단백질 추출에 영향을 주는 제 요소 즉 추출용액의 농도, 용매량, 시간, 온도, pH의 영향을 검토하고 pH에 따른 TCA 침전단백질을 정량한 결과를 요약하면 다음과 같다. 1. 식염가용성 단백질에 있어서 미역, 톳, 돌김, 잎파래, 구멍갈파래는 0.25M의 식염용액에서, 모자, 셀만모자반, 누운청각은 1.0M에서 가장 좋은 추출성적을 얻었으며, 알콜가용성 단백징 전시료(미역, 모자반, 잎파래, 둥근돌김)가
In present study, the effects of various factors including the solvent concentration, extraction time and temperature, the ratio of sample vs extraction solvent, (w/v) and pH upon the extractability of the NaCl and alcohol soluble proteins of marine algae were investigated. Eight species of fresh algae, the major ones in consumption as food, namely Porphyra suborbiculata, Undarie pinnatifida, Hizikia fusiforme, Sargassum, fulvellum, Enteromorpha linza, Sargassum kjellmanianum, Codium coarctatum, and Ulva pertusa were used for the extraction of NaCl soluble protein and dried materials of four species, Perphyra suborbiculata, Undaria pinnatifida, Enteromorpha linza and Sargassum fulvellum were used for the extraction of alcohol soluble protein. The frozen and mascerated samples were prepared by the same method described in previous paper (Ryu, 1977). And the dried materials were moistened with alcohol solution before freezing. The effect of solvent concentration on the extractability of NaCl soluble protein differed from species. The extractability of Undaria Pinnatifide, Hizikia fusiforme, Perphyra suborbiculata, Enteromorpha linza, and Ulva pertusa reached maxima at 0.25M NaCl solution while the 1.0M for Sargassum fulvellum, Saygassum kjellmanianum and Codium coarctatum. In case of alcohol soluble proteins, it was shown at
