Abstract

This study analyzed Tuber melanosporum, Tuber aestivum,and Tuber magnatum, specifically the content of 𝛽-glucan, amino acids, nucleic acid-related substances, vitamin C, and ergosterol. The 𝛽-glucan content was highest in T. magnatum (20.54%). The free amino acid content was highest in T. aestivum, with the major amino acids being cystine, glutamic acid, and aspartic acid. The total amino acid content was the highest in T. magnatum, the primary amino acids being cystine, glutamic acid, and lysine. The content of nucleotide related compounds was the highest in T. magnatum (5.09 mg/100 g). The highest content of vitamin C (10.15 mg/100 g) and ergosterol (596.91 mg/100 g) was found in T. magnatum, which had the highest useful component content among the three truffles. Additional studies investigating the variation in useful components according to collection time and growth environment are needed.

트러플로 사용되는 T. melanosporum, T. aestivum 및 T. magnatum의 특성을 파악하고자, 𝛽-glucan, 아미노산, 핵산관련 물질, vitamin C, ergosterol 함량을 분석하였다. 𝛽-Glucan 함량은 T. magnatum이 20.54%로 가장 높게 나타났다. 총 유리아미노산 함량은 T. aestivum이 가장 높게 나타났으며 주요 아미노산은 cystine, glutamic acid, aspartic acid로 나타났다. 총 구성아미노산 함량은 T. magnatum이 가장 높게 나타났으며, 주요 아미노산은 cystine, glutamic acid, lysine으로 나타났다. 핵산관련 물질 함량은 T. magnatum이 1.64 mg/100 g로 가장 높게 나타났다. 3종의 트러플 중 vitamin C와 ergosterol 함량은 T. magnatum에서 각각 10.15 mg/100 g, 596.91 mg/100 g으로 가장 높게 나타났다. 따라서 3종의 트러플 중 T. magnatum의 유용성분 함량이 가장 높은 것으로 확인되었으며, 채취시기, 생장환경에 따른 트러플들을 수집하여 추가적인 유용성분 연구가 필요한 것으로 판단된다.
