초록

표고버섯은 톱밥배지 재배기술의 발달로 세계적으로 가장 많이 생산되고 식용되는 버섯이며, 톱밥배지를 이용하여 재배된 표고버섯의 생산량이 늘고 있다. 본 연구에서는 톱밥재배 표고버섯의 품종별 식품학적 차이를 비교하고자 동일 조건에서 재배된 산조701호, 산조707호, 산조 715호, 참아람, L808 총 5품종 표고버섯의 일반성분, 영양성분 및 항산화 활성을 분석하였다. 동결건조된 표고버섯의 일반성분 함량은 회분 4.06~5.92 g/100 g, 조지방 0.75~1.02 g/100 g으로 품종별 차이가 크지 않았으나 조단백질은 21.24~29.15 g/100 g으로 품종간의 유의적 차이를 보였다. Trehalose는 산조701호에서 9.60±0.08 g/100 g으로 가장 높은 함량으로 확인되었다. 총 아미노산 조성은 glutamic acid>aspartic acid>leucine 순으로 높은 분포를 보였으며, 유의적 차이를 보인 아미노산은 glycine, alanine, valine, isoleucine, leucine, phenylalanine이었으며 산조707호, 산조715호, 산조701호, 참아람, L808 순으로 높은 함량을 보였다. 물 추출물의 총 폴리페놀 함량과 총 플라보노이드 함량은 산조715호가 3.49±0.04 mg GAE/g, 1.33±0.03 mg QE/g으로 가장 높게 나타났으며 다른 품종들과 유의적 차이를 나타내었다. 같은 톱밥배지와 환경에서 재배된 표고버섯 5 품종간의 유의적 차이가 확인된 성분은 조단백질, trehalose, 6종의 아미노산이었다. 하지만 한 곳의 임가에서 재배된 표고버섯 품종간의 비교 결과로, 품종별 시료 수를 확대한 추가실험을 통하여 품종간의 구별 가능성을 더욱 세부적으로 검토할 필요가 있다.

With the development of sawdust medium cultivation technology, Lentinula edodes (shiitake mushroom) has become the most extensively produced and consumed mushroom globally. In this study, the approximate composition, nutritional components, and bioactive compounds of L. edodes were analyzed and compared for the five sawdust-cultivated shiitake mushrooms cultivars namely Sanjo701ho, Sanjo707ho, Sanjo715ho, Chamaram, and L808. The approximate range of the composition of freeze-dried shiitake mushrooms was 4.06-5.92 g/100 g of ash, 0.75-1.02 g/100 g of crude fat, and 21.24-29.15 g/100 g of crude protein. Sanjo701ho had the highest trehalose content (9.60±0.08 g/100 g), total polyphenol content (3.49±0.04 mg GAE/g), and total flavonoid content (1.33±0.03 mg QE/g) among the other shiitake mushroom cultivars. The total amino acid content was as follows: glutamic acid>aspartic acid>leucine. Glycine, alanine, valine, isoleucine, leucine, and phenylalanine contents were significantly decreased in the following sequence: Sanjo707ho, Sanjo715ho, Sanjo701ho, Chamaram, and L808. Crude protein, trehalose, and six types of amino acids were identified as classification indicators for the five cultivars of sawdust-cultivated shiitake mushrooms.
