Abstract

The nutritional composition of Pleurotus nebrodensis fruiting body has been analyzed for medicinal and edible uses. Minerals of P. nebrodensis were found to be as follows potassium (1,612.96 mg/100 g), phosphorus (644.52 mg/100 g), magnesium (100.32 mg/100 g), sodium (97.84 mg/100 g), calcium (13.8 mg/100 g), iron (4.77 mg/100 g), zinc (4.32 mg/100 g), copper (0.88 mg/100 g) and manganese (0.55 mg/100 g) based on dry weight. Eighteen amino acids were found in P. nebrodensis. Among total amino acid, glutamic acid content was the highest (353 mg/100 g) and aspartic acid, leucine, arginine and alanine were followed. Concerning free amino acids, tryptophan, proline, alanine and isoleucine were dominant. The vitamin E content was the highest (285.31 mg/100 g), then vitamin C, niacin and vitamin $B_6$ were followed.

건강기능성 식품 개발을 위한 기초자료의 목적으로 백영고의 미네랄, 아미노산 및 비타민 함량을 조사한 결과 다음과 같다. 미네랄성분은 K, P, Mg, Na가 주성분을 이루었으며 이 중 K가 1,612.96 mg%로 가장 많이 함유하고 있었다. 유리아미노산의 총 함량은 659.86 mg%이며 필수아미노산 314.31 mg% 중 tryptophan이 93 mg%로 함량이 가장 높았고 isoleucine, valine, threonine, phenylalanine, lysine, methionine, leucine이 각각 50.06 mg%, 47.1 mg%, 43.5 mg%, 40.83 mg%, 23.62 mg%, 14.01 mg%, 2.19 mg%순으로 함유되었다. 구성 총 아미노산의 함량은 1,326 mg%이며 이 중 glutamic acid가 353 mg%로 전체 구성아미노산의 26.6 %을 차지하였고 필수아미노산은 426 mg%이었다. 또한 vitamin E는 285.31 mg%로 높은 함량을 보였고 칼슘보충에 도움을 주는 vitamin $D_3$는 0.06 mg%로 다른 버섯에 비해 함량이 높았다.
