Abstract

Composition of fatty acids (FAs) in Pleurotus ostreatus were analyzed by gas chromatography and compositional changes according to cultivar, fruitbody section and developmental stage (days after primordia formation) were investigated. Major FAs in oyster mushroom were linoleic acid, oleic acid and palmitic acid. Unsaturated FAs were higher in pileus portion than upper- or lower-stipe portion. Oleic acid content was increased with developmental days but linoleic acid content was highest at $3{\sim}4$ days after primordia formation and then decreased after that. And ratio of unsaturated FAs/saturated FAs was decreased with basidiocarp maturation.

느타리버섯(원형1호 느타리) 자실체의 부위별로 지방산 조성을 조사한 결과 linoleic acid는 갓부위에서 가장 높았고 대부위로 갈수록 낮아지는 경향이었고 stearic acid와 palmitic acid는 대부위로 갈수록 증가하는 경향이었다. 생육시기별 지방산조성은 oleic acid의 경우 버섯원기형성 후 $11{\sim}12$일 까지는 점차 증가하다가 이후부터는 감소하는 경향을 보였고 linoleic acid와 불포화지방산대비 포화지방산의 비율은 원기형성 후 $3{\sim}4$일까지는 증가하다가 그 후부터는 감소하는 경향을 나타내었다.
