맥문동 열수추출물의 일반 성분함량과 관능적 특성을 조사하였다. 건조, 분쇄한 맥문동에 4배량의 물을 가하여 3시간동안 가열추출한 추출액은 가용성 고형물 15.95%, 전당 13.15%, 비환원당 6.54%, total saponins 1.73%를 함유하며, 회분함량은 0.33%, 단백질은 0.40% 함유하였다. 주요 유기산으로는 succinic acid 111.48 mg%, malic acid 23.67 mg% 및 acetic acid 18.36 mg%였다. 가장 많이 함유된 유리아미노산은 hydroxyproline으로 열수추출물에는 1,290.0 μg%, glutamic acid는 456.2 μg%였다. 주요 무기질로는 칼륨이 151.35mg%로 가장 많았다. 맥문동 열수추출물은 쓴맛이 없었으며, 보통 정도의 단맛과 신맛을 지니며 약간의 떫은맛을 띠었다. This study was conducted to analyze the general components and to investigate sensory evaluation of hot water extract prepared from Liriopis tuber. The extract was prepared by boiling at 100℃ for 3 hr with 4-fold water. The contents of total soluble solid, non-reducing sugar, total saponin, ash and total protein were 15.95%, 6.54%, 1.73%, 0.33% and 0.40%, respectively. The contents of succinic, malic and acetic acid in the extracts were 111.48 mg%, 23.67 mg% and 18.36 mg%, respectively. The major free amino acids and minerals of the extract were hydroxyproline 1,290.0 μg%, glutamic acid 456.2 μg% and potassium 151.35 mg%, respectively. Bitter taste in the extract was not observed, whereas sweet, sour and astringent taste were observed.

Major chemical components of sweet drink and vinegar prepared with Liriopis tuber were investigated sensory quality. The contents of total soluble solid, total sugar, non-reducing sugar, total saponin, ash and protein in the processed of Liriopis products ranged 7.71~10,67%, 4.94~9,77%, 1.98~4.67%, 0.80~0.59%, 0.40~0.36%, and 0.44~0.49%, respectively. In addition, levels of succinic, malic and acetic acid in the products ranged 78.9~96,3, 23.6~6.3 and 12.7 ~2686.0㎎/100㎖ respectively, Meanwhile, the sweet drink contained 1.89㎎%(w/v) of hydroxyprolin, 0,39㎎%(w/v) of glutamic acid, 0.22mg%(w/v) of arginine, 0.15㎎%(w/v) of citruline and 0.11㎎%(w/v) of potassium. The vinegar contained 2.89㎎%(w/v) hydroxyprolin, 248.2 ㎍/100ml glutamic acid, 99.2 ㎍/100ml arginine, 205,5 ㎍/100㎖ citruline and 143.46㎍/100㎖ potassium.
