Abstract

To develop food additives from pyroligneous liquor, we first examined the physicochemical characteristics of volatile substances. The pH, gravity, acidity, solution tar, and scorched remains in the pyroligneous liquor were 2.50, 1.020, $0.8\%$ $2.31\%$ and $0.008\%$ respectively. The main compounds of pyroligneous liquor were 2,6-dimethoxyphenol (syringol), 2-hydroxy-2-cyclopenten-l-one, 1,2-benzenediol (catechol), phenol, 2 (5H)-furanone, 2-methoxyphenol (guaiacol), 5-hydroxymethyl-2 furancarboxaldehyde were found in organic phase, whereas catechol, 1,4 : 3,6-dianhydro-${\alpha}d$-glucopyranose, cyclopropyl carbinol, 5-hydroxymethyl-2 furancarboxaldehyde in aqueous phase.

목초액을 천연보존료로 이용하기 위하여 기계식전용 탄화로에서 제조된 목초액을 대상으로 이화적인 특성 및 휘발성분의 함량을 분석하여 다음과 같은 결과를 얻었다. 목초액은 pH, 비중, 산도, 굴절률, 투과률은 각각 2.40, 1.020, $0.8\%$, $1.354\%$, $89.05\%$이었고, 용해타르 및 작열잔사는 각각 $2.31\%,\;0.008\%$이었다. 한편 무기성분은 Al 0.11, Cu 4.13, Fe 2.92, Mn 0.15, Zn 4.37, Ca 3.49, K 5.89, Mg 0.43, Na 6.88 mg/L 함유하고 있었으나 유해중금속인 Pb, Cd, As, Hg, Cr 등은 검출되지 않았다. GC-MS에 의한 목초액의 성분을 분석한 결과 유기성 분획에 함유된 화합물은 ketones 및 diketone계 화합물이 5,472.3 ${\mu}g/100mg$, phenol류가 5,170.3 ${\mu}g/100mg$, methoxyphenol 화합물이 6,002.7 ${\mu}g/100mg$, dimethoxyphenol 화합물이 5,790.7 ${\mu}g/100mg$, furan 및 pyran 화합물이 5,604.5 ${\mu}g/100mg$, pyrocatechol류가 4,790.3 ${\mu}g/100mg$ 함유되어 있었다. 성분별로는 2, 6-dimethoxyphenol (syringol) 3,453 ${\mu}g/100mg$으로 가장 높은 함량을 나타냈고, 2-hydroxy-2-cyclopenten-1-one 2,480.3 ${\mu}g/100mg$, catechol 2,097.5 ${\mu}g/100mg$, Phenol 2,037.2 ${\mu}g/100mg$, 2(5H)-furanone 1,826.7 ${\mu}g/100mg$, 2-methoxyphenol (guaiacol) 1,812.9 ${\mu}g/100mg$, 5-hydro-2-furancarboxaldehyde (HMF) 1,636.8 ${\mu}g/100mg$함유되어 있었다. 수용성 분획에서는 catechol 501.2 ${\mu}g/100mg$, cyclopropyl carbinol 442.0 ${\mu}g/100mg$, 2-hydroxy-2-cyclopenten-1-one 270.0 ${\mu}g/100mg$, 5-hydro-2-furancarboxaldehyde 120.5 ${\mu}g/100mg$, 1,4:3,6-dianhydro-$\alpha$-d-glucopyranose 121.9 ${\mu}g/100mg$ 함유되어 있었다.
