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, , , 이었고, 용해타르 및 작열잔사는 각각 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

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, and 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--glucopyranose, cyclopropyl carbinol, 5-hydroxymethyl-2 furancarboxaldehyde in aqueous phase.
