Abstract

Sarcodon aspratus (Berk.) S. Ito is a wild mushroom commonly consumed in Korea due to its beneficial effects on health. However, only limited information on the volatile and nonvolatile constituents of S. aspratus is available. In the present study, the total concentration of mushroom soluble sugars, including glucose, trehalose, sucrose, and xylose, was found to be 202.5 mg/kg. The total contents of free and essential amino acids were 2,592.1 mg/kg and 1,249.5 mg/kg, respectively; arginine, lysine, methionine, and valine were the major amino acids present. The contents of total 5'-nucleotides and flavor 5'-nucleotides in S. aspratus were 2,510.7 mg/kg and 773.4 mg/kg, respectively. The volatile components of S. aspratus were collected by simultaneous distillation-extraction (SDE) and analyzed by gas chromatography-massspectrometry (GC-MS). A total of 27 volatile compounds were isolated and identified. The most abundant was l-octen-3-ol, which accounted for more than 68% of total volatiles; other important compounds were 2-octen-1-ol, 1-octen-3-one, and 2-octenol. Our results provide preliminary data for the development of S. aspratus as a food material.

본 연구는 능이버섯의 식품학적 이용성 증진을 위한 기초적인 연구로써 능이버섯의 휘발성 및 비휘발성 기호성분을 분석하였다. 단맛에 관여하는 유리당은 glucose, trehalose, sucrose, xylose가 검출되었고 총 함량은 202.5 mg/kg이었다. 단맛, 쓴맛 및 감칠맛에 관여하는 아미노산의 함량을 분석한 결과, 필수아미노산과 총 유리아미노산의 함량은 각각 1,249.5 mg/kg과 2,592.1 mg/kg으로 나타났다. 버섯의 5'-nucleotide 함량을 분석한 결과, 감칠맛에 관여하는 5'-nucleotide의 함량은 773.4 mg/kg으로 측정되어 총 5'-nucleotide의 30.8%를 차지하였다. 능이버섯의 향기성분을 분석한 결과, 6종의 alcohol류, 4종의 ketone류, 8종의 aldehyde류 및 3종의 함황화합물을 비롯하여 총 27종의 향기성분이 확인되었다. 이 중 1-octen-3-ol이 전체 향기성분의 68%를 차지하였고, 2-octen-1-ol, 1-octen-3-one 그리고 2-octenol 순으로 나타났다. 이러한 결과는 능이버섯을 이용한 기능성 식품 및 식품재료로서의 이용성 증진을 위한 기초 자료로 제공될 수 있을 것으로 판단된다.
