막장, 재래식 된장 및 막장과 재래식의 혼용 된장을 주원료로 제조한 쌈장의 일반 성분, 유리 아미노산, 향기성분 등의 품질을 검토한 결과는 다음과 같다. 쌈장은 수분 $51.2{sim}53.5%$, 염분 $11.47{sim}14.05%$, 총당 $20.38{sim}23.6%$, 환원당 $8.44{sim}9.29%,;pH;4.76{sim}5.53$의 범위로 총당은 막장구, 환원당은 혼용구의 쌈장에서 높았다. 쌈장의 유리 아미노산으로 glutamic acid가 $230.6{sim}310.9mg/100;g$으로 가장 높았다. 쌈장의 명도, 적색도, 황색도 값은 재래식 된장구 및 혼용구된장구의 쌈장에서 높았다. 쌈장의 휘발성 향기 성분으로 acid류 13종, alcohol 11종, ester 7종, aldehyde 3종, alkane 4종, phenol 4종, pyraine 3종 등 총 54종이 동정되었다. Ethanol, acetic acid ethyl ester, 3-methyl butanoic acid, 2,4-hexadienoic acid, acetic acid등은 면적비율이 높아 쌈장 향기의 주성분으로 추측된다. 막장구에서는 pentanoic acid methyl ester, 4-methoxy-2-buten-1-ol이 , 재래식 된장구에서는 2-methyl-1-propanol, butanoic acid, 3-methyl butanoic acid 등이, 혼용구에서는 ethanol, ethyl acetate, 2,4-hexadienoic acid 등의 향기성분이 각각 타시험구 보다 면적 비율이 높은 것으로 나타났다.
Samjangs (Korean-style mixture of soybean paste) were prepared using magjang, traditional doenjang (Korean style soybean paste), and mixture of traditional doenjang and magjang (a kind of Korean style soybean paste) as a main composition. Charateristics including volatile compounds were investigated. Total sugar in samjang by using magjang was higher than that of other treatment while reducing sugar of the mixed treatment was high. Glutamic acid $(230.6{sim}310.9;mg/100;g)$ was highest among free amino acids. Hunter color values of samjang with magjang was lower than those of others. Volatitle flavor components of smajang were identified with GC and GC-MSD. Fifty four components including 11 alcohols, 7 esters, 13 acids, 3 aldehydes, 4 alkanes, 4 phenols, 3 pyrazine and others were found in samjangs. Ethanol, acetic acid ethyl ester, 3-methyl butanoic acid, 2,4-hexadienoic acid and acetic acid might be major volatile components considering of high peak area. Pentanoic acid methyl ester and 4-methoxy-2-buten-1-ol were higher than other components in samjang with magjang while 2-methyl-1-propanol, butanoic acid and 3-methyl butanoic acid were in samjang with traditional doenjang and ethanol, acetic acid ethyl ester and 2,4-hexadienoic acid were in the mixed treatment.
